Your pages are live, the content is better than what’s ranking, and the backlink profile is still nearly empty while competitors keep collecting links and mentions. Which SEO tools for backlinks actually find, earn or protect those links? Backlink work splits into three jobs: a link index for research, a contact and outreach step for earning the link, and a monitor for the links you already have. Google Search Console covers the free starting point.
I’m Fassih Fayyaz, an SEO specialist and web designer working in search since 2017 — agency first, then consulting and freelance projects for freelancers, small businesses and solo operators. Ahrefs, Semrush, Screaming Frog and Google Search Console are the backlink tools I open daily, and the rest of this list is written from vendor documentation and published pricing.
You’ll finish knowing what each tool is genuinely good at, what it costs, where it stops, and which backlink job it fits, so you can add them in the right order and start with the free layer. Nobody paid to be in this list. I don’t follow commission rates, every tool gets a real downside in writing, and I only claim experience I can back.
Quick Comparison / Summary
This table lines up each backlink tool with the category it belongs to, the one backlink job it handles best, and the score as a plain number — enough to shortlist a tool before you read its full entry.

Which SEO tools are actually worth using for backlinks?
Semrush runs backlink audit, competitor gap analysis and outreach from one account, Ahrefs holds the deepest backlink data for link-gap research, and Google Search Console is the free first-party report of the links Google counts. Pitchbox and Respona cover outreach, and a small site can start free.
- Semrush: backlink audit, competitor gap and outreach in one account.
- Ahrefs: the deepest backlink data for link-gap research.
- Google Search Console: the free first-party report of the links Google counts.
- Pitchbox: prospecting, sequencing and deliverability at volume.
- Respona: content-led personalized outreach.
Google Search Console is where the free path starts, because it reports the links Google has already counted rather than an estimate from a third-party crawl.
15 Best SEO Tools for Backlinks
Below are the 15 best seo tools for backlinks:
1. Semrush — Best for all-in-one backlink research and outreach
Semrush is an all-in-one SEO platform whose backlink half covers Backlink Analytics, Backlink Gap, Backlink Audit and a Link Building Tool. The same account also runs keyword research, site audits, rank tracking and content tools. What that removes is the hand-off between analysis and outreach: the platform that finds the domains linking to your competitors also holds the prospect list, the outreach emails and the monitoring that tells you when a placement disappears.
I open Semrush most days, and the reason is that a campaign never leaves the tool. You spot a gap, you turn it into a prospect list, you send the pitch, and you watch the link land and stay. Most stacks lose a week in that hand-off somewhere between a spreadsheet and three subscriptions.
Run Backlink Gap with your domain plus up to four competitors and switch to the Best tab to list the referring domains that link to them but not to you. Open Backlink Analytics on any profile in that list for referring domains, anchor text, and new and lost links over time.
Send the chosen prospects into the Link Building Tool, connect a mailbox, work the Prospects, In Progress and Monitor stages, and email from inside the platform. Run Backlink Audit on your own domain to read the toxicity score across the profile and export a disavow file for Google. The link monitoring view then shows a removed or broken placement as lost instead of letting it surface in the next audit by surprise.
The honest catch is freshness. Semrush’s backlink index updates more slowly than Ahrefs’, so the newest links can take a while to appear, and I trust it for the campaign view rather than for spotting a link the hour it goes live. The platform’s breadth also becomes the problem if all you want is a backlink check, because the backlink modules are not sold separately and there is no permanent free tier of the toolkit — the free Backlink Checker and Backlink Analytics are limited standalone tools. The published plans are Pro at $139.95 a month, Guru at $249.95, Business at $499.95 and a 7-day free trial, though Semrush has restructured its plans around newer lines, so confirm the current price and trial terms at checkout.
Key features
- Backlink Analytics and Backlink Gap against up to four competitors
- Backlink Audit with toxicity scoring and disavow-file export
- Link Building Tool with prospect stages and built-in email outreach
- Authority Score domain metric
- Link monitoring for active, lost and broken links
Pros
- Research, prospecting, outreach and monitoring in one workflow
- Backlink Gap builds a qualified prospect list quickly
- Doubles as a full SEO suite for keywords, audits and rank tracking
Cons
- A backlink index that updates more slowly than Ahrefs’
- Expensive if backlink data is all you need
- No permanent free plan, and the listed starting prices vary by plan
2. Ahrefs — Best for deep backlink data and link-gap research
Ahrefs is an SEO data platform built on its own crawler. Site Explorer reports any domain’s backlinks, referring domains, anchor text and link growth, and Backlink Gap compares your link profile against competitors’. It answers the question every backlink campaign starts with — who links to my competitors and not to me — from one of the largest live link indexes, and it reaches the same data through broken-link and unlinked-mention routes.
The index is the product. When I need to know how many referring domains a page has earned, which anchor text they use, or whether a link appeared this week, Ahrefs is the tool I reach for, because depth and freshness decide whether a gap list is worth pitching.
Type a domain or URL into Site Explorer to read its backlink profile: total backlinks, referring domains, anchor text distribution and link growth over time. Use Backlink Gap with your domain and up to five competitors to isolate the referring domains that link to them and not to you.
Search Content Explorer for the most-linked pages on a topic, then switch on the unlinked-mentions filter to find pages that mention you without linking. The broken-backlink view lists competitor pages that still attract links but no longer resolve, which is where a replacement page of yours earns a fast placement.
The limit is scope: there is no outreach, CRM or email sequencing anywhere in the product, so Ahrefs stops at research and you still need a sending tool. Credit limits also meter heavy bulk pulling and exports on the lower plans, which is a real cost once a campaign is running weekly. The depth of the reports is a genuine learning curve if you have not worked with backlink data before, and Ahrefs does not publish its tiers on the marketing site, so no vendor-confirmed price exists — the quoted Lite figures range from about $108 to $129 a month, with plans spanning roughly $99 to $999 a month, so confirm the current number at checkout. A free public Backlink Checker handles one-off lookups. Ahrefs suits deep backlink data and competitor link-gap research.
Key features
- Site Explorer backlink profile with referring domains and anchor text
- Backlink Gap against up to five competitors
- Content Explorer with unlinked-mention filtering
- New and lost backlink monitoring
- Broken backlink finder
Pros
- Among the largest and freshest link indexes available
- Competitor link-gap prospecting in minutes
- A free public Backlink Checker for one-off checks
Cons
- No outreach or CRM module
- Credit-metered usage on entry plans
- Steep for beginners, with quoted starting prices that disagree
3. Google Search Console — Best for free first-party link data
Google Search Console is Google’s own free reporting tool for site owners. Its Links report shows the external sites linking to you, your most-linked pages and the link text they use, taken from Google’s index. It is the only backlink data that comes straight from the search engine that ranks you, which makes it the reference point for checking what a paid index is missing and the cheapest way to start.
Every paid tool estimates a link profile from its own crawl. Search Console shows what Google counted, and for most small sites those two lists are not the same. Connecting it is the first thing I do on a new property, before any subscription.
Open the Links report for the verified property and read Top linked pages under External links to see which of your pages attract the most links. Use Top linking sites to spot unknown or spammy domains, and Top linking text to read the anchor text distribution Google records.
Export the report as CSV or to a Google Sheet using Latest links, which returns up to 100,000 of the most recently discovered links. Read the Internal links view alongside it to check whether your strongest pages pass equity to the pages you are trying to rank, and submit a disavow file from the same property when a paid audit flags links worth removing.
The report is a sample rather than a complete inventory: Google states that some URLs are omitted, and the on-screen tables truncate at 1,000 rows. Data is grouped by root domain, so protocol, subdomain and subdirectories are stripped and www and non-www merge into one line, and it covers only your own verified properties, so it cannot analyze a competitor’s links at all. The data also arrives with a lag of roughly 24 to 48 hours, which suits reporting and not catching a link the minute it goes live. It is free with a Google account, holds up to 1,000 properties per account, and suits anyone who wants free validation of the links Google actually counts.
Key features
- Links report with Top linked pages, Top linking sites and Top linking text
- CSV and Google Sheets export up to 100,000 rows
- First-party data direct from Google’s index
- Internal links view
- Free with any verified property
Pros
- The only first-party backlink data from Google
- Completely free
- Exports feed a spreadsheet or a Looker Studio report
Cons
- A sampled, root-domain-grouped list rather than a full index
- Data arrives with a lag of roughly 24-48 hours
- Your own site only, never a competitor’s

4. Pitchbox — Best for high-volume outreach with deliverability controls
Pitchbox is an outreach platform for link building. It turns a keyword, a competitor or an imported list into a prospect pipeline, finds and verifies contacts, and runs the email sequences that follow. It covers the half of link building a backlink index cannot: turning a list of domains into contacted people, and keeping sending reputation intact while doing it at volume.
Most outreach fails on deliverability long before it fails on the pitch, and Pitchbox treats that as the main problem rather than an afterthought.
Start a campaign from a keyword, a search-operator query, a competitor backlink pull through the Ahrefs or Semrush integration, or an imported CSV, and let the prospecting engine build the list. Filter prospects by domain rating, organic traffic, keyword count and referring domains using saved presets, and blacklist sites you never want to contact again.
Work the Inspection Queue to approve or reject each prospect with its page, metrics and contact on one screen, then run personalization before sending. Send with Smart Templates and conditional follow-ups, and watch inbox placement, blacklists and domain reputation in the Deliverability Center. Link monitoring afterwards shows which placements went live and which quietly disappeared.
The honest limit is scale. Pitchbox is built and priced for teams sending a serious volume of pitches — the vendor positions it for operations building 20 or more links a month — so it is expensive for occasional outreach, and the entry Pro plan leaves out the deliverability monitoring and bulk personalization that justify the platform for most teams. There is also no backlink analysis of its own, so a research tool still has to sit beside it. The vendor’s own pricing page lists Pro at $300 a month billed monthly or $210 a month billed annually, but the quoted figures elsewhere run from $165 a month to a $550-$1,500 a month range, so confirm the current plan and whether a trial is available before you commit. It suits agencies and in-house teams running high-volume link outreach.
Key features
- Prospecting engine with Ahrefs, Semrush, Moz and Majestic metric filters
- Contact discovery and verification
- Personalization and reply assistance
- Deliverability monitoring and blacklist checks
- Link monitoring after placement
Pros
- Prospecting, sequencing, CRM, deliverability and reporting in one platform
- The strongest deliverability tooling in the category
- Handles multi-client agency workflows
Cons
- Expensive entry point for low-volume outreach
- Steep learning curve
- Automated prospecting occasionally returns off-topic sites
5. Respona — Best for content-led personalized outreach
Respona began as content-first outreach software that finds relevant articles and podcasts, locates and verifies the right contact, and runs personalized sequences. Its current pricing page sells managed placements on publisher sites delivered by its own team. It starts from content relevance rather than a scraped domain list, which is how you find pages that would credibly link to something you have already written instead of emailing strangers.
That distinction matters more than it sounds. A domain list sorted by authority tells you a site is strong; a content search tells you the site already writes about your subject, which is the only reason an editor has to say yes.
Run a content-first search for articles, blog posts or podcasts on your topic, then filter the results by metrics such as domain rating. Pick a pre-built campaign template — Skyscraper, Product Review, Guest Post, Podcast Outreach or Resource pages — to generate the prospect list.
Let the contact finder pull a direct email and LinkedIn profile, then personalize each pitch with snippets drawn from the prospect’s own content. Track replies in the shared inbox and the Insights tab. If you would rather buy the result than run the campaign, order a managed placement by tier and the publisher relationship sits with Respona instead of you.
Two things have moved. The company has shifted its pricing and help content toward done-for-you placements, so self-serve software pricing is no longer published and the two products are easy to confuse — the managed tiers run $100, $160, $240, $400 and $500 per placement, against an older software subscription quoted from $99 to $399 a month. Contact lookups also consume credits with no published allowance, so costs escalate on a large campaign, and there is no API access while live templates cannot be edited. Managed placements run on a default 28-day turnaround, with 14 days as a paid extra, and no trial terms are published. Respona suits content-led outreach where relevance beats volume.
Key features
- Content-first prospecting across articles, blogs and podcasts
- Pre-built campaign templates
- Multi-source contact finder with verification
- Personalization built from prospect content
- Shared inbox, sequences and campaign analytics
Pros
- Finds prospects by content relevance rather than domain metrics alone
- Strong personalization and accurate contact data
- Available as either software or a managed placement service
Cons
- Credit costs escalate on large campaigns
- No API access, and live templates cannot be edited
- The pricing model has shifted to per-placement, so budgeting is harder
6. BuzzStream — Best for team-wide outreach relationship management
BuzzStream is an outreach CRM built for link building and digital PR. It stores contacts and their history, discovers contact details and site metrics from a list of URLs, sends tracked sequences, and monitors the links you earn. It stops outreach living in spreadsheets: one record holds the conversation history, the site metrics and the campaign stage, so nobody on the team pitches the same person twice.
The duplicate pitch is the quiet killer of a link campaign. Two people emailing the same editor a week apart reads as spam, and the damage lands on the domain, not just the campaign. A shared record is the fix.
Upload a list of URLs on the Research screen and let BuzzStream fill in contact details, website stats and social metrics, then segment the list by authority and outreach history. Build the sequence on the Email screen: choose a template, personalize from the contact’s history and recent posts, schedule the send and automate follow-ups for non-repliers.
Use the Manage screen to see who has been contacted, who replied and who needs a follow-up, and assign contacts to teammates so ownership is explicit rather than assumed. Save prospects while browsing with the Chrome extension, and use the Links report to check monitored links by domain authority, anchor text and link type.
Two limits are worth knowing before you buy. The built-in contact discovery returns generic addresses often enough that most teams pair it with a dedicated email finder, so budget for a second subscription. The interface also takes a few weeks to feel comfortable with, and capacity is capped by contact count and monitored links on the entry plan. The vendor publishes two different plan tables on its own site, with Starter listed at $49 a month for 500 contacts and 1,000 monitored links against a $24 a month figure, so confirm the tier names and prices on the signup page rather than trusting a summary. There is no free plan; a 14-day free trial carries the evaluation. BuzzStream suits teams that need an outreach CRM rather than a backlink index.
Key features
- Outreach CRM with full contact profiles and history
- Automated email sequences and follow-ups
- Chrome extension for saving prospects as you browse
- Duplicate-contact prevention across campaigns
- Link monitoring and project reporting
Pros
- Purpose-built for link building and digital PR
- Prevents duplicate outreach across a team
- Monitors the links you earn in the same tool
Cons
- Dated interface with a learning curve
- Built-in contact data is inconsistent
- No backlink index of its own, and the vendor’s own plan tables conflict
7. BuzzSumo — Best for linkable content and journalist research
BuzzSumo is a content research and media-monitoring platform built on an index of billions of articles. Backlink Analyzer tracks the links a URL or domain picks up over time and alerts you when new ones appear. It shows what already earns links in a niche and who shared it, so the asset you pitch is built on evidence rather than a guess about what publishers might want.
Most link campaigns fail upstream of the outreach: nobody wants the page. BuzzSumo answers whether a topic has ever attracted links and shares before you spend a week writing about it.
Search a topic, keyword or URL in Content Analyzer to see the most-shared articles, then click through to top sharers to see who amplified each piece. Turn on Backlink Analyzer to track link growth for a domain or URL over time, and set a backlink alert so new links arrive by email or into Slack.
Search the journalist database by beat and open a profile for recent articles and contact details to build a media list. The Chrome extension pulls engagement and backlink counts for any article while you browse, which is useful when you are deciding in a browser tab whether a piece is worth pitching.
The useful outreach half is not in the entry plan. The media database, which is the part that turns research into a pitch, starts at the PR & Comms tier, and the vendor labels it beta on its own pricing page. Alert counts and historical depth are capped by tier even though searches are advertised as unlimited, and the platform is content research rather than backlink analysis, so it cannot replace a link index. Published pricing is Content Creation at $199 a month billed yearly, PR & Comms at $299, Suite at $499 and Enterprise at $999, against a $119 a month starting figure quoted elsewhere, so check the current tiers and the free trial length at signup. BuzzSumo suits finding linkable content and the journalists who cover it.
Key features
- Content Analyzer with engagement and backlink data
- Backlink Analyzer with link-growth tracking
- Journalist database and media lists
- Backlink, brand and keyword alerts
- Chrome extension for on-page metrics
Pros
- Connects content performance to link acquisition
- Journalist and influencer data in the same tool
- Question Analyzer surfaces real audience questions
Cons
- The entry plan excludes the media database
- Expensive for small teams
- Limited value in some B2B niches, and no link index of its own
8. Majestic — Best for deep historical link data with trust metrics
Majestic is a link-intelligence tool built on its own Fresh and Historic link indexes. Trust Flow scores link quality by proximity to trusted seed sites, Citation Flow scores raw link volume, and Topical Trust Flow breaks authority down by subject. It answers the quality question rather than the counting question: the ratio between Trust Flow and Citation Flow exposes profiles that look big but are built on low-trust links.
When a pitch looks too good, Majestic is where I check it. A site with a healthy referring-domain count and a Trust Flow that sits far below its Citation Flow is usually a link farm with good presentation.
Enter a domain or URL in Site Explorer, read the Summary screen, then move through the Ref Domains, Backlinks, New, Lost, Anchor Text, Topics and Related Sites tabs. Read Trust Flow and Citation Flow together and check Topical Trust Flow for subject relevance before you decide a site is worth contacting.
Use Clique Hunter and Compare Sites to find the domains that link to several competitors and not to you. Add targets to Backlink Campaigns to watch Trust Flow over time, or export the data and pull it through the API into your own workflow. The Link Context view shows where on the page a link sits, which separates an editorial mention from a footer link.
Majestic does no keyword research, rank tracking or outreach, so it sits beside a broader suite rather than replacing one, and the Historic Index is not continuously rebuilt, so older-link reporting can lag well behind the Fresh Index. Trust Flow and Citation Flow are vendor metrics rather than Google ranking factors, and each search is capped by data rows and analysis units, which bites when you export competitor lists in bulk. Plans are LITE at $49.99 a month, PRO at $99.99 and API at $399.99, with annual billing at $41.67, $83.33 and $333.33 plus a 7-day money-back guarantee. Majestic suits judging link trust and digging into a domain’s link history.
Key features
- Fresh Index and Historic Index backlink databases
- Trust Flow, Citation Flow and Topical Trust Flow
- Clique Hunter and Compare Sites link-gap tools
- Link Context showing placement on the page
- Bulk Backlink Checker across up to a million URLs
Pros
- The deepest historical link data of the tools compared
- Trust metrics no other tool in the group replicates
- Topical relevance scoring for prospect vetting
Cons
- No keyword research, rank tracking or outreach
- Dated interface and a narrow focus on links
- No organic traffic estimates, and the Historic Index lags
9. Hunter.io — Best for verified prospect email discovery
Hunter finds and verifies professional email addresses. Domain Search lists the addresses on a company’s site, Email Finder returns one person’s address with a confidence score, Email Verifier checks deliverability before you send, and Campaigns sends the sequence. It fixes the step most backlink campaigns get wrong — emailing a generic contact form or a dead address instead of a verified person — which is what turns a prospect list into placements.
A bounced pitch costs more than the email: enough bounces and your domain’s sending reputation drops, which affects every campaign that follows.
Run a domain through Domain Search to get every public address on the site with its source and confidence score, filtering by department. Use Email Finder with a name plus company domain for one person’s address, and the bulk finder for the rest of an exported prospecting list.
Check the list through Email Verifier before sending so invalid and risky addresses are removed rather than bounced. Load the verified contacts into Campaigns, or into BuzzStream or Pitchbox, and connect Gmail or Outlook to send. A Chrome extension covers one-off lookups while you are reading a site.
Credits are consumed per reveal and per verification and are shared across searching and verifying, so a large list can exhaust a plan quickly — budget the credits before you upload a five-thousand-row list rather than after. Accuracy also drops in Asia, Latin America and smaller markets, so coverage is uneven outside major English-language markets. Most importantly, it carries no backlink or authority data, so it can reach a prospect but cannot qualify one. There is a permanent free plan with 50 credits a month, one connected email account and 500 recipients per sequence; paid tiers are Starter at $49 a month ($34 billed yearly), Growth at $149 and Scale at $299, with Enterprise custom. Hunter suits finding and verifying the addresses behind a prospect list.
Key features
- Domain Search with confidence scores and sources
- Email Finder for named contacts
- Bulk email verification before sending
- Chrome extension for one-click lookups
- Built-in Campaigns with Gmail and Outlook
Pros
- High accuracy with confidence scores before you send
- A genuinely usable free plan
- A Chrome extension that fits manual prospecting
Cons
- Credits drain quickly on large lists
- Weaker coverage outside major markets
- No SEO or backlink metrics
10. SE Ranking — Best for multi-client backlink and ranking tracking
SE Ranking is an all-in-one SEO platform whose backlink module combines a Backlink Checker, Backlink Monitoring and a Backlink Gap Analyzer with rank tracking and site audits in the same account. It puts link acquisition and ranking movement side by side, so you can see whether a placement moved the target page instead of judging a campaign on link counts alone.
That pairing is the useful part for client work. A monthly report that shows three new referring domains and no position change tells a different story than one that shows the same three links and a page moving from position 12 to 4.
Run a domain or an exact URL through the Backlink Checker, set the match mode, and read Domain Trust, Page Trust, anchor text, dofollow versus nofollow and the toxicity score for each link. Add the links worth protecting to Backlink Monitoring by hand or by importing them from Google Search Console, and let the alerts flag links that vanish or lose their attributes.
Use the Overview charts to read gained and lost referring domains over a chosen range, and click a point to filter the backlink table below it. Compare against up to five competitors in the Backlink Gap Analyzer, and tick toxic links to generate a disavow file ready for Search Console.
The backlink index is smaller than Ahrefs’ or Majestic’s and refreshes monthly rather than continuously, so SE Ranking monitors better than it discovers — do not treat it as a prospecting index. There is also no outreach or prospecting tooling in the platform, and bulk API access to backlink data starts at the Growth tier while the plan comparison publishes no numeric backlink caps. Published pricing is Core at $129 a month and Growth at $279 a month with Enterprise custom, against a $65 a month figure quoted elsewhere, so confirm the current tiers and limits at signup. A 14-day free trial needs no card. SE Ranking suits agencies tracking backlinks and rankings across many client accounts.
Key features
- Backlink Checker with Domain Trust and Page Trust
- Backlink Monitoring with new and lost alerts
- Backlink Gap Analyzer against five competitors
- Toxicity score and disavow-file generation
- Rank tracking and site audits in the same account
Pros
- Backlink monitoring is genuinely useful for campaign verification
- Multi-client projects with white-label reporting
- Cheaper than Ahrefs or Semrush for monitoring work
Cons
- A smaller, monthly-refreshed backlink index
- No built-in prospecting or outreach
- Quoted starting prices disagree
11. Skrapp.io — Best for bulk contact discovery from domain lists
Skrapp.io is a B2B contact-finding tool that turns a domain list or a LinkedIn profile into verified work email addresses, with a bulk uploader, a verifier and a LinkedIn extension. It is built for the shape of a link-building prospecting list — many domains, many editors — so it finds contacts in bulk from an Ahrefs or Semrush export instead of one page at a time.
That is the difference between a list of 800 domains and an outreach campaign. Doing it by hand takes days and still misses the person who actually decides what gets published.
Upload a CSV of domains, or names plus domains, to the bulk finder and let the column mapper return contacts with an Email Status of Valid, Catch-All, Invalid, Unknown or Pending. Set the roles you will accept, such as SEO manager, content lead or editor, and cap the contacts per domain so the credit budget lasts the campaign.
Open a LinkedIn or Sales Navigator profile and click the extension to pull the person’s verified email, title and seniority into a list. Export the verified contacts to CSV or sync them to a CRM, then hand them to the outreach tool that sends the pitches.
It finds and verifies contacts but sends nothing, so it always needs an outreach tool beside it. Credits are charged only for valid or catch-all results, which makes budgeting unpredictable, and daily search caps apply on top of the credit balance. List exports and CRM sync start at Professional, and API access is Enterprise-only, which is the main reason a heavier user outgrows the cheap tiers. There is a permanent free plan with 50 credits and daily caps of 10 people searches, 5 company searches and 3 AI searches; Professional runs from $39 a month ($29 billed annually) up to $199 a month for 25,000 credits, and Enterprise starts at $349 a month. Skrapp.io suits bulk contact discovery from a filtered prospect list.
Key features
- Bulk email finder for uploaded domain lists
- Email Finder and verifier with status
- LinkedIn Chrome extension
- Role and seniority filters
- CRM integrations and REST API
Pros
- Built for bulk domain lists rather than one-off lookups
- Charges only for deliverable contacts
- Low entry price
Cons
- No outreach or sequencing of its own
- Needs a filtered domain list first or credits burn quickly
- Exports and API sit on higher tiers
12. Screaming Frog — Best for pre-campaign broken-link and internal-link audits
Screaming Frog SEO Spider is a desktop crawler for Windows, macOS and Linux that audits a site and reports every internal and external link with its status code, anchor text, crawl depth and source page. New links are only worth what the target page can pass on, so the crawler finds the broken links, redirect chains and orphan pages that would waste the equity you are about to build.
I run a crawl before any link campaign, because there is no point buying or earning links to a page Google cannot reach or that leaks equity through a redirect chain. It is also the tool that confirms the links already on the site point where you think they do.
Enter the site’s root URL and start the crawl, then work the External tab to see every outbound link with its status code and the page it sits on. Use the broken-link view to find pages that still hold links but return an error, which are the easiest replacement-link pitches to write because the page owner already has a problem to fix.
Check the internal linking metrics — link count, crawl depth and the calculated link score — to see whether equity reaches the pages you are promoting. Connect the Majestic, Ahrefs or Moz API under Configuration to pull external link metrics into the crawl, and schedule recurring crawls to compare changes over time. Custom extraction pulls specific elements off a page when you need data the default reports do not include.
It is a desktop crawler with no backlink index of its own, so it only analyzes sites you crawl yourself and cannot tell you who links to a competitor. Large crawls are bounded by the machine’s memory, the free version caps at 500 URLs per crawl and drops JavaScript rendering, custom extraction and API integrations, and the paid license is per user and renews every year at £199, shown as $279 per year in the currency switcher, with volume discounts from five licenses. Screaming Frog suits auditing broken links and internal link equity before a campaign.
Key features
- Site-wide broken link detection
- Redirect chain and loop reporting
- Internal link metrics and crawl-depth analysis
- External link metrics via the Majestic, Ahrefs and Moz APIs
- Scheduled crawls and crawl comparison
Pros
- Finds broken links at a scale browser extensions cannot
- Strong pre-campaign audit before building links
- The free tier is usable on small sites
Cons
- No outreach and no backlink database
- Steep learning curve and a dated desktop interface
- The license is per user and renews every year
13. WhitePress — Best for international placement buying without outreach
WhitePress is a link-building marketplace where you buy sponsored articles, guest posts and link insertions directly from publishers instead of emailing them. It covers more than 100,000 websites across dozens of countries and languages. It is the alternative to cold outreach in markets where you have no contacts: filter publishers by country, language, traffic and metrics, then buy the placement instead of pitching for it.
The trade is control for speed. You skip weeks of prospecting, and you accept publisher-supplied inventory in return, which means the vetting work is entirely yours and the price is the only quality signal the marketplace gives you up front.
Filter the publisher database by country, language, category, traffic and SEO metrics — the platform publishes more than 40 filters — to build a shortlist for the target market. Use the existing-link exclusion filter so publishers that already link to you are hidden and every purchase adds a new referring domain.
Order through the article flow: add or order the content, compare the offers and conditions, pay into escrow and set the publication date. Track what you bought with the free Backlink Manager and the Google Analytics, Search Console and Looker Studio integrations. The same account also sells link insertions, brand mentions and copywriting, so you can buy the content and the placement in one order.
Placement quality varies enormously by price tier and the inventory is publisher-supplied, so an expensive domain and a cheap one sit in the same interface with the same guarantees. Buying links for ranking purposes is against Google’s spam policies, whatever a marketplace’s visibility guarantee says, and the advertised 36-month visibility guarantee is conditional: interruptions under nine consecutive days do not count, and publishers may switch a link to nofollow without breaching it. WhitePress publishes no starting price; placements are pay-as-you-go with publisher prices visible only after sign-in, and the quoted range runs from around $100 for smaller niche sites to $20,000-plus for major outlets, so confirm each offer before ordering. It suits buying vetted guest-post placements in international markets.
Key features
- Publisher marketplace across dozens of markets and languages
- More than 40 publisher filters including existing-link exclusion
- Article publication, link insertion and brand mentions
- Copywriting marketplace for the content itself
- Free Backlink Manager with reporting integrations
Pros
- Skips cold outreach entirely in unfamiliar markets
- Strong international and multilingual coverage
- Per-publisher pricing is visible before you order
Cons
- Quality varies sharply by tier
- No monthly price to budget from, since every placement is bought separately
- Paid links carry ranking risk and the guarantee is conditional
14. Mangools LinkMiner — Best for budget backlink analysis
LinkMiner is the backlink tool inside the Mangools suite. It shows a domain’s backlinks with Link Strength, Citation Flow and Trust Flow, and previews where each link sits on the source page. It makes backlink analysis affordable and readable for someone who has never opened a link index, and it bundles the keyword research and rank tracking that make the link data actionable.
The interface is the feature. Most link indexes are built for people who already know what a referring domain is, and LinkMiner is the one that assumes you do not, which is why it is the sane first paid step for a freelancer.
Enter a domain or URL in the Find backlinks box to get the profile with Link Strength scores, then sort by Link Strength to prioritize targets. Switch between All links, New links and Lost links — a new link is one discovered in the past 90 days — and turn on one link per referring domain to clean up a prospecting list so you are not pitching the same site three times.
Click any backlink to preview the referring page inline with the anchor text highlighted, so placement can be judged without opening another tab. Mark the best prospects as favorites so they collect into lists, and use the same suite’s KWFinder and SERPWatcher for the keyword side, which is what makes the link data useful rather than a standalone number.
LinkMiner runs on the Majestic index rather than its own, and the headline backlink total is drawn from the Fresh Index while the browsable list mixes in historical data, so the two numbers on screen do not match and low-authority pages can be missed. It also has no backlink audit, spam scoring or disavow-file tool, so cleanup needs another product, and no outreach of any kind. Lookups are metered on a rolling 24-hour window. Pricing is Basic at $30.50 a month, Premium at $40.50 and Agency at $70.50, each including all five tools, with a vendor price test that has also published Basic at $24.50, so check the current figure. A permanent free plan needs no card and resets every 24 hours. LinkMiner suits affordable backlink analysis for freelancers and beginners.
Key features
- Backlink analysis with Link Strength, Trust Flow and Citation Flow
- Inline referring-page preview
- New and lost link tracking
- One-link-per-domain filtering
- A free 24-hour-reset plan inside a five-tool suite
Pros
- The clearest interface in the category for beginners
- Five tools bundled at the price of one
- A genuinely free entry plan
Cons
- Fewer referring domains than the big indexes
- No audit, spam score or disavow tooling
- No outreach features, and lookups are metered
15. Linkody — Best for low-cost link monitoring and disavow cleanup
Linkody is a backlink monitoring tool: it watches the links you and your competitors have, checks their status every 24 hours and alerts you when a link is removed, switched to nofollow or broken. Link building is wasted if placements quietly disappear, so a cheap watcher that flags a lost link the day it happens protects the spend a research tool helped you make.
Publishers rotate sponsored content, redesign pages and move to https without telling anyone. The link you paid for or earned can vanish, and the first you hear of it is a traffic dip three months later.
Add your own domains and up to five competitor domains per project, then set the email report to daily or weekly for new and changed links. Use Link Intersect to list the pages that link to several competitors but not to you, which is the shortest route to a prospecting list when you already know the niche.
Read Ahrefs DR, Moz DA and PA, Spam Score and Trust Flow on each link, and open the Link Visualizer to see where it sits on the source page. Send spam-flagged links to the disavow tool and export a file ready for Google Search Console, or pull the whole report as a white-label PDF when a client wants evidence of the work.
It monitors rather than discovers, and the index behind it is small, so links can appear late or be missed entirely, which makes it a poor prospecting tool. Checks run on a 24-hour cycle, so it is not real-time detection, and the trial withholds the CSV and PDF exports that make the reporting useful. There is no keyword research, rank tracking or outreach in the product either. Pricing is Webmaster at $14.90 a month ($11.20 billed annually), Advanced at $24.90 ($18.70), Pro at $49.90 ($37.40), Agency at $99.90 ($74.90) and Agency XL at $153.90 ($115.40), covering 2 to 100 sites and 500 to 50,000 monitored links, and annual billing includes three months free. Linkody suits backlink monitoring and disavow cleanup on a small budget.
Key features
- 24-hour backlink status checks with alerts
- Disavow-file generator
- Competitor monitoring for up to five domains per project
- Anchor text distribution and link metrics
- White-label PDF reports
Pros
- Very low entry price for constant monitoring
- Spots lost or nofollowed links quickly
- Disavow cleanup in the same interface
Cons
- Narrow feature set beyond monitoring
- A smaller index than the major platforms
- No published API, and a 24-hour detection window
Start with what is free and first-party, then pay for the one job genuinely eating your week — a link index when you need to find prospects, an outreach tool once pitches become regular, and a monitor once placements need protecting. If you buy placements instead of earning them, put the money into vetting the site first, because the placement itself is the smaller risk.
Which backlink tool is best for each job?
Each backlink job has one best-fit tool, and rarely the same one:
- All-in-one SEO platforms: Semrush at #1 — it runs the backlink audit, the competitor gap and the outreach campaign from one paid account, so you’re not stitching three subscriptions together.
- Backlink analysis and link indexes: Majestic at #8 — Trust Flow, Citation Flow and Topical Trust Flow judge what a link is actually worth, which is the question a raw link count never answers.
- Link building outreach and CRM: Pitchbox at #4 — prospecting, contact finding, sequencing and deliverability monitoring sit in one pipeline, which is what high-volume outreach needs to stay out of spam folders.
- Contact discovery and email verification: Hunter.io at #9 — Domain Search, Email Finder and Email Verifier turn a raw prospect list into verified people before a single email goes out.
- Content research and link prospecting: BuzzSumo at #7 — it shows which pages already earn shares and links in your topic and who published or shared them, so the asset you pitch is built on evidence.
- Backlink monitoring and audits: Screaming Frog at #12 — it crawls your site for broken links, redirect chains and internal link equity, the pre-campaign cleanup that keeps new links from being wasted.
- Link marketplaces: WhitePress at #13 — when you have no outreach contacts in a market, you filter publishers by country, language and traffic and buy the placement instead of pitching for it.
- Free backlink data and validation: Google Search Console at #3 — its Links report is the only backlink data that comes straight from Google, so it shows which of your links the search engine actually counts.
Which link building tools add SEO data to outreach?
An SEO link building tool adds qualification data — domain rating, referring domains, anchor text and toxicity — to a contact list a generic outreach platform would otherwise send to blind. Semrush, Ahrefs, SE Ranking, Pitchbox and Respona carry that data; Hunter.io and Skrapp.io find the contact but bring no link metrics with it.
Generic outreach software answers one question: who do I email, and when? It holds a contact, sends a sequence and tracks replies. It has no idea whether the domain is worth pitching, so the qualification has to arrive from somewhere else. An SEO-qualified link building tool carries the metrics into the prospect record, which is what turns a raw list into a ranked one.
The metrics that do the qualifying work are domain rating or Authority Score, referring-domain count, organic traffic estimate, anchor text distribution and toxicity. Pitchbox and Respona integrate with the research platforms rather than maintaining their own indexes, so their filters pull domain rating, organic traffic, keyword count and referring domains from an Ahrefs, Semrush, Moz or Majestic connection. Semrush and SE Ranking keep the index and the prospect list in one account, which removes the export step entirely. Ahrefs and Majestic carry the data but send nothing, so pairing them with an outreach CRM is the practical route. Both arrangements work, and the choice comes down to whether you prefer one subscription with a shorter workflow or two subscriptions with a deeper index.
Here is how the ranked tools split on this:
- Research and outreach in one account: Semrush carries Backlink Gap, Backlink Audit and the Link Building Tool, so the prospect record is created inside the platform that measured the domain.
- Deepest index, no sending: Ahrefs supplies the qualification data through Site Explorer and Backlink Gap and stops at research, so an outreach tool sits beside it.
- Index with outreach filters attached: Pitchbox pulls Ahrefs, Semrush, Moz and Majestic metrics into its prospecting filters and its Inspection Queue.
- Content-led qualification: Respona filters prospects by domain rating after a content search, so the metric sits on top of a relevance match rather than in place of it.
- Monitoring-first platform: SE Ranking carries Domain Trust, Page Trust and toxicity into the same account as rank tracking, with no outreach layer.
- Contacts without metrics: Hunter.io and Skrapp.io verify the address and return no domain rating, referring domains or anchor data, so they need a research platform upstream.
One more distinction matters if you are comparing an SEO link building platform with a plain prospecting tool. A link building platform holds the campaign state — who was contacted, what they replied, which link went live — and that record is the asset you keep between campaigns. A contact finder holds none of it. When a campaign is judged six months later, the platform that stored the sequence and the placement history is the one you can report from, which is why the sending side of the stack tends to outlive the research subscription.
Google Search Console is the free exception. It returns no domain rating and no toxicity score, but it is the only source that confirms the link Google counted.
Which link building platforms suit solo builders and agencies?
A solo builder runs the free layer plus one paid research tool and rarely needs more, while an agency needs multi-client projects, seat management and white-label reporting. The split lands on Google Search Console, Mangools LinkMiner, Linkody and Hunter.io for one person, and on BuzzStream, Pitchbox, SE Ranking, Semrush and Ahrefs for a team.
Best free and entry-level stack for a solo builder. Google Search Console reports the links Google counts for nothing. Mangools LinkMiner gives backlink analysis and keyword research in one account at $30.50 a month with a free plan that resets every 24 hours. Hunter.io finds and verifies the contact with a permanent free plan of 50 credits a month, and Linkody watches the placements you earn from $14.90 a month. That covers find, verify and monitor for the price of one mid-tier subscription elsewhere, and it is the honest stack for a freelancer with two or three sites.
Best first paid step for outreach. Hunter.io at $49 a month for 2,000 credits or Skrapp.io from $39 a month adds the contact layer to a list you already have. Outreach sending comes next, and it is the step where a solo builder should be honest about volume: BuzzStream starts at $49 a month with 500 contacts and 1,000 monitored links, which is plenty for a one-person campaign and not enough for an agency running several clients through the same account.
Best for agencies and in-house teams. BuzzStream and Pitchbox both handle shared prospect records, so two people never pitch the same editor, and Pitchbox adds deliverability monitoring and the Inspection Queue that make volume survivable. SE Ranking carries multi-client projects, white-label reporting and rank tracking beside the backlink data, which is what a monthly client report needs. Semrush and Ahrefs supply the research depth a team can bill for. The team features are the reason to pay more: seat limits, project limits and white-label output are the axes that separate a $49 a month plan from a $424 a month one.
Scale changes what you need long before it changes what you can afford. One site with a modest link profile needs an index, a contact finder and a monitor. Ten client sites need campaign separation, seat management and reporting that carries their logo rather than a screenshot. The platform that matters at ten sites is rarely the one that was cheapest at one site, so buy the free and entry tiers first and let the client list decide when to move up.
Which backlink tools find the links your competitors have?
Semrush and Ahrefs both run a competitor backlink gap, Ahrefs comparing up to five competitors and Semrush four, and both list referring domains rather than raw links. SE Ranking compares five, Majestic’s Clique Hunter covers several at once, and Linkody’s Link Intersect handles five per project; Google Search Console cannot analyze a competitor at all.
Backlink gap analysis is the fastest route to a qualified prospect list, because a domain that already links to three sites in your niche has demonstrated it links out on your topic. Every tool below does the same job in a different shape, and the differences are how many competitors they compare, whether they show referring domains or individual links, and what metrics come attached.
Here is how the gap views compare:
- Semrush Backlink Gap — enter your domain plus up to four competitors, then switch to the Best tab for referring domains that link to them and not to you, with Authority Score attached to each.
- Ahrefs Backlink Gap — the same view across up to five competitors, with referring domains, link counts per domain and the ability to sort by the strength of the domains you are missing.
- SE Ranking Backlink Gap Analyzer — five competitors against your domain, with Domain Trust and Page Trust on each referring domain and a toxicity score beside the list.
- Majestic Clique Hunter and Compare Sites — Clique Hunter queries several domains at once for the link sources they share, and Compare Sites returns the full link profile of each target for manual comparison.
- Linkody Link Intersect — up to five competitors per project, with the pages linking to several of them and not to you, plus Ahrefs DR and Moz DA on each result.
Two practical notes. First, the cheapest gap list is the one you already have: a domain that links to a competitor and mentions you without linking is a reclamation rather than a pitch, so check unlinked mentions before building a fresh prospect list. Second, gap data ages quickly, because the domains in it were qualified months ago, and a site that sold placements since then is no longer the same target. Re-check each domain’s trust metrics before you pitch it rather than trusting a list you exported last quarter.
What can free backlink and SEO tools actually do?
Free backlink tools do three things well: Google Search Console reports the links Google counted, public checkers score a profile you already have, and permanent free plans give you a fixed monthly allowance of analysis. Free tools cannot run bulk prospecting, send outreach at volume or monitor links continuously.
The ceiling is worth stating plainly. Google Search Console is the only wholly free backlink data source in this list, and its report is sampled and grouped by root domain. Everything else either gives you a small allowance of a paid product or a trial that expires. That is enough to check a profile, verify a contact and learn an interface, and not enough to run a campaign.
The permanent free plans, with their real caps:
- Google Search Console — no tiers and no card, up to 1,000 properties per account, 1,000 rows on screen and 100,000 rows per export.
- Hunter.io free plan — 50 credits a month for domain, finder and verifier lookups, one connected email account and 500 recipients per sequence, plus a free Chrome extension.
- Skrapp.io free plan — 50 credits with daily caps of 10 people searches, 5 company searches and 3 AI searches.
- Mangools LinkMiner free plan — no card required, with limits that reset every 24 hours inside the five-tool suite.
- Screaming Frog free version — 500 URLs per crawl on a desktop install, without saving crawls, JavaScript rendering, custom extraction or API integrations.
The free tiers that are trials rather than plans:
- Semrush — a 7-day free trial, with standalone free Backlink Checker and Backlink Analytics tools that sit outside the paid toolkit.
- SE Ranking — a 14-day free trial with no card, plus a metered public Backlink Checker that returns a snapshot.
- BuzzStream — a 14-day trial, with no free plan.
- Pitchbox — trials arranged through a demo, with no published length.
- Majestic — a 7-day money-back guarantee on Lite and Pro rather than a free plan, alongside free tools including a Backlink Checker and the Majestic Million.
Free tools also have a quality ceiling that has nothing to do with the allowance. A public checker returns authority and referring-domain counts without the referring-domain list, the anchor distribution or the toxicity detail you need to decide whether a specific site is worth a pitch, and it covers one domain at a time, which is not how a prospect list works. Read a free checker as a first filter and a paid index as the working data.
Three jobs never come free at volume. Bulk prospecting needs a crawl of the whole web, so it is metered by credits or analysis units. Outreach sending needs mailbox infrastructure, warm-up and deliverability monitoring. Continuous monitoring checks hundreds of thousands of links every 24 hours, which is why Linkody charges from $14.90 a month for it rather than offering it free.
What does automating link building actually look like?
Automating link building means handing four tasks to software: sequenced follow-ups, bulk contact discovery, scheduled crawls that detect changes, and monitoring alerts when a link breaks or disappears. Choosing who deserves a pitch and writing something worth answering stay with you.
Automatic link generation — software that manufactures backlinks without a person behind them — does not exist in any form worth buying, and the tools that advertise it produce links on sites built for the purpose. Google’s spam policies treat those links as link spam, which makes the shortcut a future cleanup job rather than a campaign.
The parts that genuinely automate:
- Send the follow-up sequence. Pitchbox, Respona and BuzzStream all automate conditional follow-ups, so a non-reply gets a second and third touch on a schedule without anyone maintaining a to-do list.
- Find and verify contacts in bulk. Hunter.io and Skrapp.io turn a domain list into verified addresses in one pass, and both return a status per contact so invalid entries never reach the sending tool.
- Crawl on a schedule. Screaming Frog’s scheduled crawls compare one crawl against the last, which surfaces new broken links, changed redirects and lost internal links without anyone clicking Start.
- Watch the placements. Linkody checks every link every 24 hours and alerts on lost, nofollowed or broken links, and BuzzSumo’s backlink alerts do the same for a domain or a single URL.
What does not automate is the judgment. Software can return four hundred domains that link to your competitors; deciding which twenty deserve a pitch still comes down to relevance, whether the site would credibly link to what you have, and whether the editor has published anything similar before. The pitch itself resists automation too, because personalization has to reference something specific about the page you are asking to be added to, and a template that fills in a first name and a domain gets filtered as bulk mail within a week.
The honest way to use automation is as a filter, not a replacement. Automate the forty hours of finding, verifying, sending and checking, so the two hours of choosing and writing get your full attention. Teams that invert that ratio send more pitches and land fewer links, and the cost shows up later as a damaged sending domain.
Which all-in-one SEO platforms cover backlinks and everything else?
Semrush, Ahrefs and SE Ranking each carry backlink data beside keyword research, rank tracking and site audits, and that breadth earns its price once you work on several sites or run regular audits. For a one-site owner, a specialist like Majestic, Mangools LinkMiner or Linkody does the backlink job for less.
An all-in-one SEO platform bundles several jobs into one subscription and one login. The trade is real: you pay for features you may never open in exchange for a shorter workflow and one data source across the account. The question is not which platform is biggest, it is which of its extra modules you will actually use twice a month.
Here is what each suite adds beyond links:
- Semrush — keyword research, site audits, rank tracking, content templates, PPC data and the Link Building Tool that connects the backlink half to outreach, which no other suite here does.
- Ahrefs — the deepest link index of the three, plus keyword research, rank tracking, site audits and Content Explorer for finding pages that already earn links.
- SE Ranking — backlink monitoring, rank tracking, site audits, white-label client reporting and multi-project management at a lower entry price than either of the other two.
Now the point where the suite stops making sense. If you own one site and all you need is a competitor gap list, Linkody covers Link Intersect and monitoring from $14.90 a month, and Mangools LinkMiner covers backlink analysis and keyword research for $30.50 a month with a free plan that resets daily. Neither replaces everything a suite does, and neither charges $129 a month to do the one job you actually have. Majestic is the same calculation for link quality: $49.99 a month for the deepest historical link data here, with no keyword research, rank tracking or outreach attached.
The moment the suite earns its price is when the modules start substituting for each other. If you would otherwise pay for a rank tracker and a site crawler and a backlink index, one subscription is cheaper and the data joins up across reports. If you would pay for one of those three, the suite is two subscriptions you did not need. A practical rule: count how many of the platform’s modules you opened in the last month, and let that number set the budget rather than the feature list. For a freelancer with one site, that number is usually one, which is why the specialist tools hold their place in this list rather than being folded into a suite recommendation.
Do you need a backlink app or a desktop tool?
Most backlink tools are browser apps, a few extend the browser with an extension for one-click lookups, and only Screaming Frog SEO Spider is a desktop install. A crawler of your own site needs desktop software; everything that queries someone else’s index works in a tab.
Form factor decides how a tool fits a working day. A desktop crawler can hold an entire site’s link graph in memory and keep it while you filter, which is why Screaming Frog runs locally rather than in a browser. Index queries are the opposite: the heavy data sits on a vendor’s servers and the browser only renders the result, so Ahrefs, Semrush, SE Ranking, Majestic, Linkody and Mangools LinkMiner all work in a tab.
Browser extensions do a different job from the web app they belong to. Hunter.io and Skrapp.io both ship an extension for the moment you are reading a site or a profile and want the contact without leaving the page. BuzzSumo’s extension pulls engagement and backlink counts on any article while you browse. BuzzStream’s extension saves a prospect to a campaign as you find it, which is the manual prospecting loop most outreach tools are built around.
Screaming Frog is the one tool in the list with no browser equivalent, and the reason is the crawl. Auditing a 5,000-page site means fetching every URL, following every redirect, rendering JavaScript pages and storing the result while you sort it by status code — work that needs local memory and a file system. The free version caps a crawl at 500 URLs and drops JavaScript rendering, custom extraction and the API integrations, which is enough to audit a small site and not enough to audit a client’s.
Everything else is web-first, so a phone or a tablet gets you most of the way.
Which analytics tell you whether a backlink campaign worked?
Six numbers decide whether a backlink campaign worked: the referring domains gained, the lost links replaced, the target page’s rank movement, the profile’s toxicity score, the anchor text mix and the reply-to-placement rate. No tool here tracks the pages you pitched and never won.
A campaign report needs two halves: what the link profile gained, and what the target page did about it. Link counts tell you the outreach worked; rank movement beside them tells you whether the link was worth having.
The numbers worth recording per placement:
- Referring domains gained, not total backlinks, because ten links from one domain are one link for ranking purposes.
- The target page’s position for the keyword the placement was meant to help, recorded before the link went live and again 30 days after.
- Link status, so a removed, broken or nofollowed placement shows up as a loss rather than a permanent line in a report.
- Toxicity score for the profile, checked whenever new links arrive from a source you did not choose.
- Anchor text distribution, because an unnatural concentration of exact-match anchors is a pattern rather than a link.
- Reply and placement rate per outreach wave, so you can tell a bad list from a bad pitch.
Here is where each number comes from:
- Rank tracking beside backlink monitoring — SE Ranking holds both in one account and reports gained and lost referring domains beside position movement.
- Link status and lost-link alerts — Linkody checks every link every 24 hours and flags removals, nofollow changes and broken links.
- Toxicity and disavow reporting — Semrush’s Backlink Audit scores toxicity across the profile and exports a disavow file, and Linkody generates one from flagged links.
- First-party confirmation — Google Search Console’s Links report shows which of the new links Google actually counted, which is the only external check on a vendor’s own index.
- Anchor text mix — Ahrefs Site Explorer and Majestic’s Anchor Text tab both report the distribution, with Majestic adding the Trust Flow and Citation Flow split per anchor.
One gap is worth naming. No tool in this list reports the pages you pitched that never replied, or the placements that were promised and never published, because that record only exists in the outreach platform’s campaign history. If you want a true placement rate rather than a link count, keep the sent, replied, won and lost stages in the outreach tool and report from there. And keep the date on every number: a referring-domain count with no date attached cannot be compared to anything, which is what turns a monthly report into a trend.
What do Google’s own tools show about your backlinks?
Google’s own reporting shows the links Google has counted for your own verified properties: the external sites linking to you, your most-linked pages and the anchor text they use, all free in the Search Console Links report. It cannot show a competitor’s links, and it samples rather than lists everything.
First-party backlink data means the link list comes from the index that ranks you rather than from a third-party crawl. That makes Search Console the reference point when a paid index and reality disagree: if a link shows in Ahrefs or Semrush and not in Search Console after a few weeks, Google has not counted it yet, and no amount of reporting in the paid tool changes that.
The Links report gives you three tables. Top linked pages ranks your own URLs by the number of links pointing at them, which shows which content actually earns links and therefore what to write more of. Top linking sites lists the external domains, sorted by how many links each one sends, which is where an unknown or spammy domain shows up first. Top linking text reports the anchor text Google records, which is the distribution that matters for over-optimization checks.
The limits are structural rather than temporary. The report is a sample: Google states that some URLs are omitted, and the on-screen tables truncate at 1,000 rows, with the CSV and Google Sheets export returning up to 100,000 of the most recently discovered links. Data is grouped by root domain, so http and https, subdomains and subdirectories collapse into one line and www and non-www merge, which hides the exact URL that links to you. And it covers only your own verified properties, so it answers what links to you and never what links to a competitor. Data also arrives with a lag of roughly 24 to 48 hours, and the account holds up to 1,000 properties.
The one thing Search Console is genuinely for in a link campaign is closing the loop. A paid index finds the opportunity, the outreach tool wins the link, and Search Console confirms Google counted it. That confirmation is the difference between a placement and a result, and it is free. What it cannot do is show you who links to your competitors.
Where do on-page tools fit in a backlink campaign?
On-page SEO is a different job with different tools, and the only on-page task that belongs in a backlink campaign is the broken-link and internal-link audit that stops new links from being wasted. Schema, titles, content optimization and Core Web Vitals sit outside this list of backlink tools.
The boundary is worth holding because the two disciplines fail in different places. On-page work changes the page so it can rank for a query; backlink work changes who points at the page. A link to a page that does not answer its query, or that Google cannot crawl, spends money to amplify a fault, which is why the audit comes before the outreach rather than after.
Three on-page checks protect link equity directly. A broken-link crawl finds internal and outbound links that return errors, so the equity flow you are about to build does not pour into a 404. Redirect chain reporting finds pages that pass their authority through two or three hops instead of one, which is the most common silent leak on a redesigned site. And crawl-depth reporting shows whether your strongest page passes link equity to the pages you are trying to rank, or hoards it. Screaming Frog handles all three in a single crawl, and it is the only tool in this article whose job is auditing your own site rather than somebody else’s links.
For everything else on the page side — title tags, heading structure, schema markup, internal anchor text, image compression and page speed — the tools and the method are a separate subject with a separate stack. If that is the work you are doing next, the on-page SEO tools guide covers it. This article stays with links: finding them, earning them, buying them where that makes sense, and keeping them once they exist.
Frequently Asked Questions
Which backlink tool earns its price first?
Semrush and Ahrefs earn their price first, because backlink research is the job you cannot do for free at any scale — Semrush if you want the audit, the competitor gap and the outreach campaign in one paid account, Ahrefs if the depth of the link index is what decides a pitch. The free path still starts with Google Search Console.
Semrush carries the campaign from Backlink Gap through the Link Building Tool to link monitoring, which is the shortest route from a prospect list to a placement. Ahrefs supplies the deepest index and the fastest gap list, and then stops at research. If your budget covers one subscription, Semrush does more of the job; if it covers two, Ahrefs plus an outreach CRM reaches further into the gap data.
Do backlink tools still earn their keep?
Yes — links are still work worth tooling for in 2026, because earned links and the outreach that produces them decide who gets cited in both classic search and AI answers. Search interest in backlink tooling has not faded: practitioner communities keep asking what people actually use for backlink work, and search suggestions keep returning the same requests for backlink tools for beginners and for free options. The honest evidence is the behavior of the people doing the work, who keep paying for link indexes, contact data and monitoring.
Which five tools cover a backlink campaign end to end?
Semrush, Ahrefs, Google Search Console, Pitchbox and Respona are the five tools that cover a full backlink campaign — one research platform, one deep index, one free confirmation layer and two outreach systems for the sending half. Four of the five need a paid plan. If you want only the free path, Google Search Console plus the permanent free plans in Hunter.io, Skrapp.io and Mangools LinkMiner cover the research, contact and monitoring steps at small volume.
Has AI search changed how you build links?
No — AI answers absorb some clicks, but earned links and the outreach that produces them still decide which pages and brands get cited, so link building remains the work rather than a legacy tactic. The tooling has moved with the change rather than against it: link indexes now track brand mentions and how a brand appears in AI answers, content research tools report which pages earn links before you commission anything, and the automation layer handles the finding, verifying and sending. What changed is the surface a link supports, not the reason to earn one.
Which SEO tools should a backlink campaign start with?
A backlink campaign starts with Google Search Console for the free first-party view, then adds one link index for prospecting and one contact or outreach tool once pitches become regular. Google Search Console reports the links Google already counts and takes a disavow file, so it establishes the baseline before any subscription. The link index comes next, because prospecting is the job you cannot do by hand at any scale, and the outreach layer follows when the prospect list outgrows a manual send.
How far do free backlink tools actually go?
Free backlink tools go as far as checking, verifying and monitoring at small volume — Google Search Console for first-party link data, Hunter.io and Skrapp.io at 50 credits a month, Mangools LinkMiner’s free plan that resets every 24 hours, and Screaming Frog’s 500-URL crawl — and they stop at bulk prospecting, outreach sending and continuous monitoring. That ceiling is structural rather than stingy: each of those three jobs needs a web-scale crawl or sending infrastructure somebody maintains. Plan the free layer for the first month of a small site and budget for one paid tool as soon as the prospect list passes a few dozen domains.
Conclusion
The problem you started with has not changed: the pages are published, the content is doing its job, and the backlink profile is still thin while competitors collect links and mentions. It comes down to the right SEO tools for backlinks matched to the job you are actually stuck on — research, outreach or protection — and not to the biggest brand in the category.
If I were starting today, I would connect Google Search Console first, because it shows the links Google has already counted and costs nothing. Then add one link index for prospecting — Semrush if you want the audit, the competitor gap and the outreach campaign in one paid account, Ahrefs if the depth of the link data is what decides your pitches. Add a contact or outreach tool once pitches become regular, and add a monitor when placements need protecting rather than hunting. The free layer carries the first month; the paid spend follows the job.
