Backlink analysis is the diagnostic half of link building. Before you earn a single new link, you need to know who already links to you, how strong and relevant those links are, where your competitors get theirs, and whether anything in your profile looks manipulative. That is the work these tools do, and the honest starting point is that no single index sees the whole web.
We ranked them by the jobs that actually matter in a link audit: reading a full referring-domain list, judging link quality, comparing against competitors, monitoring new and lost links, and starting free for a site you own. If your goal is the outreach side, see our best SEO link building tools guide instead.
What a backlink analysis tool should do
See the full profile
A useful tool shows every referring domain and backlink with enough history to spot new, lost, and persistent links.
Judge link quality, not just count
Authority metrics, relevance, anchor distribution, and spam signals matter more than a raw backlink number.
Reveal competitor links
The fastest way to find link opportunities is to see who links to the sites already ranking above you.
Give you first-party truth
For your own site, Google Search Console shows the links Google actually counts—start there before paying.

Ahrefs
Best for: Anyone who needs the most complete picture of any site's backlink profile
Ahrefs built its reputation on backlink data, and Site Explorer is still the reference implementation of backlink analysis. You can see every referring domain, run a link intersect against competitors, audit your own profile for toxic links, and track new and lost links over time. Domain Rating and URL Rating give you fast, comparable authority signals for triage.
Where it shines
- Largest live backlink index with frequent crawler refreshes
- Link Intersect, best-by-links and new/lost link reports
- Domain Rating and URL Rating for quick authority triage
- Free Ahrefs Webmaster Tools tier for verified site owners
Consider before buying
- •Premium pricing relative to all-in-one suites
- •Credit-based limits on some reports and exports
Pricing: From $129/month. Confirm plan limits, index size, and current pricing before purchase.
Visit AhrefsSemrush
Best for: Teams that want backlink analysis inside a full SEO and competitor workflow
Semrush Backlink Analytics covers referring domains, anchors, referring IPs, and a toxicity score, then connects that data to keyword research, position tracking, and technical audits in the same platform. Backlink Audit turns a profile review into a prioritized disavow list, which is the part of link analysis most people actually need to act on.
Where it shines
- Backlink Audit with a clear toxic-link review workflow
- Links data joins directly to keywords, content, and PPC research
- Competitor backlink gap and bulk analysis tools
- Strong reporting for agencies managing many clients
Consider before buying
- •Link index is smaller than Ahrefs' on some niches
- •The suite's breadth means a steeper learning curve
Pricing: From $139.95/month. Confirm plan limits, index size, and current pricing before purchase.
Visit SemrushMajestic
Best for: SEO specialists who want a second, historically deep source of link data
Majestic is the original backlink database and still offers the deepest historical coverage for some sites. Trust Flow and Citation Flow rate link quality and quantity on separate scales, and Topical Trust Flow shows whether links come from genuinely relevant neighborhoods. It is a useful cross-check when one tool's index looks thin.
Where it shines
- Very deep historical backlink and referring-domain history
- Trust Flow and Topical Trust Flow for topical relevance checks
- Standalone link data without paying for an unneeded suite
Consider before buying
- •Interface and reporting feel dated next to newer suites
- •No keyword, content, or technical SEO features
Pricing: From $49.99/month. Confirm plan limits, index size, and current pricing before purchase.
Visit MajesticMoz Pro
Best for: Prospect vetting and quick relative-authority checks using DA and Spam Score
Moz Pro's Link Explorer is where Domain Authority and Page Authority originated, and it remains the quickest way to compare sites on a familiar 0-100 scale. Spam Score flags profiles that resemble known manipulative patterns, and the link-intersect and top-pages reports make it practical for prospecting as well as auditing.
Where it shines
- Domain Authority and Page Authority are widely recognized benchmarks
- Spam Score helps screen low-quality link prospects
- Link Explorer plus MozBar for on-page prospect review
Consider before buying
- •Index refreshes less frequently than Ahrefs
- •DA is proprietary, so treat it as relative rather than absolute
Pricing: From $49/month. Confirm plan limits, index size, and current pricing before purchase.
Visit Moz ProSE Ranking
Best for: Small teams and agencies that need backlinks, ranking, and audits in one affordable plan
SE Ranking combines a backlink checker with rank tracking, site auditing, competitor research, and client reporting for a fraction of enterprise pricing. The backlink module gives you referring domains, anchors, competitor comparisons, and a disavow file generator, which is enough for most day-to-day link work at an SMB or agency budget.
Where it shines
- Backlinks, rankings, audits, and reporting in one subscription
- Competitive and cost-effective against premium suites
- Friendly interface for client-facing reporting
Consider before buying
- •Link index is smaller than Ahrefs or Semrush
- •Some deep enterprise reporting is limited
Pricing: From $65/month. Confirm plan limits, index size, and current pricing before purchase.
Visit SE RankingSpyFu
Best for: Competitor link research when cost matters more than index size
SpyFu is built around competitive intelligence, and its backlink reports show where rivals earn links alongside their paid and organic keywords. For the price, it is a fast way to build a backlink target list from competitors without committing to an enterprise contract, even though its link index is the smallest of the paid tools here.
Where it shines
- Combinable link and keyword intelligence on competitors
- Low entry price with unlimited search-history data
- Quick to learn for solo marketers and small teams
Consider before buying
- •Smaller, less frequently refreshed link index
- •Less editorial depth than link-first platforms
Pricing: From $39/month. Confirm plan limits, index size, and current pricing before purchase.
Visit SpyFuUbersuggest
Best for: Beginners and small businesses doing occasional backlink checks
Ubersuggest is a low-cost way to see who links to a domain, what anchors they use, and which of your pages attract links. It will not match Ahrefs on index size or freshness, but as a first paid tool or an occasional check, it removes the biggest cost barrier to doing any backlink analysis at all.
Where it shines
- Very low entry price, including lifetime deals
- Simple backlink and keyword reports in one dashboard
- Chrome extension for quick spot checks
Consider before buying
- •Noticeably smaller index and slower refresh
- •Limited depth for technical or agency-scale work
Pricing: From $29/month (lifetime options available). Confirm plan limits, index size, and current pricing before purchase.
Visit UbersuggestAhrefs Webmaster Tools
Best for: Owners of a verified site who want real Ahrefs link data for free
Ahrefs Webmaster Tools, now branded Ahrefs Free, gives verified site owners free access to Site Explorer data for their own domain, including backlinks, referring domains, organic keywords, and a site audit. It uses the same index as paid Ahrefs, so the free tier is genuinely useful rather than a token sample, though it is limited to sites you can verify.
Where it shines
- Same link index as paid Ahrefs, scoped to your verified sites
- Backlink, organic keyword, and site-audit data at no cost
- A natural first step before upgrading to full Site Explorer
Consider before buying
- •Only works for sites you can verify ownership of
- •No competitor backlink analysis and fewer export options
Pricing: Free. Confirm plan limits, index size, and current pricing before purchase.
Visit Ahrefs Webmaster ToolsGoogle Search Console
Best for: Every site owner: it is the only first-party link data Google will show you
Google Search Console is not a full backlink analysis suite, but its Links report is authoritative because it comes straight from Google. You can see your top linked pages, top linking sites, top anchor text, and whether Google has marked any links as nofollowed or as part of a manual action. Start here, then use a paid tool to fill in the competitor and toxicity gaps.
Where it shines
- First-party data direct from Google at no cost
- Top linking sites, pages, and anchor text for your own domain
- Pairs with performance and indexing data for a complete own-site view
Consider before buying
- •No competitor backlink data and limited link samples
- •No link-quality, toxicity, or trend metrics
Pricing: Free. Confirm plan limits, index size, and current pricing before purchase.
Visit Google Search ConsoleHow to choose a backlink analysis tool
If you only own one site: begin with Google Search Console and Ahrefs Webmaster Tools. They are free, and between them you get first-party link data plus real third-party link metrics for the domain you control.
If you do competitor research: Ahrefs is the default for its link index and Link Intersect report, with Semrush as the closest all-in-one alternative. Add Majestic as a second opinion when a competitor's profile looks unusually thin in one tool.
If budget is the constraint: SE Ranking, SpyFu, and Ubersuggest each deliver the core referring-domain and anchor reports at a much lower price. You trade index size and refresh frequency, not the basic workflow.
However you choose, record a baseline first: referring domains, authority trend, and anchor distribution. Compare that baseline against two or three competitors, and only then decide whether the gap is about link volume, link quality, or relevance. A tool is useful when it turns that comparison into a repeatable task rather than a one-off curiosity.
