Melhores ferramentas de verificação de backlink em 2026 (comparado)

A backlink checker is the difference between guessing at your link profile and actually seeing it. Backlinks still carry real weight as a ranking signal in 2026, and the only way to audit your own links, spot the toxic ones, and reverse-engineer what is working for a competitor is to query a tool that has already crawled the web and stored the results. This guide compares the best backlink checker tools available now, from the deepest paid indexes to the free options worth knowing.

Prices quoted below are each vendor's published monthly list rate in USD as of September 2026, taken from their own pricing pages. Annual billing is cheaper almost everywhere, taxes are usually excluded, and SEO vendors change their packaging often, so treat every figure as a starting point and confirm it on the vendor's site before you buy.

It pairs with our main best SEO tools guide and our best keyword research tools roundup, so you can cover links and keywords together.

Best backlink checkers at a glance

Tool	Best for	Standout strength	Entry price (monthly list)
Ahrefs	Overall link data	One of the largest live link indexes	Starter $29; Lite $129
Semrush	Links inside a full suite	Backlink Audit with a toxicity score	SEO plan $139
Moz Pro	Beginners	Domain Authority and Spam Score	Mid-market subscription; see Moz
Majestic	Link specialists	Trust Flow, Citation Flow, Historic Index	Lite $49.99
SE Ranking	Ongoing link monitoring	Backlink Checker plus Backlink Monitor	Core $129
Serpstat	Affordable all-in-one	Backlink analysis inside an SEO suite	Individual $50
Ubersuggest	Small sites and low budgets	Simple backlink overview	Entry plan $29
SpyFu	Competitor research	Backlink searches plus PPC history	Basic $39

Two notes on reading that table. First, the entry price is rarely the price you end up on, because link-heavy work burns through row limits and credits fast. Second, price tiers do not map cleanly to index quality: Majestic costs a fraction of Ahrefs and has a deeper historical archive, while a cheap all-in-one may be perfectly adequate if you only need a monthly sanity check.

What separates a good backlink checker from a bad one

Index size and freshness. The more links a crawler has found, and the more recently it revisited them, the more complete your picture. A tool that reports links that died six months ago is worse than useless for outreach.
Quality metrics. Authority, trust, and spam scores let you sort thousands of rows into a shortlist. Every one of these is a vendor's own estimate, not a Google metric, so use them to rank links relative to each other rather than as an absolute verdict.
Competitor comparison. Seeing which sites link to rivals but not to you is the single most actionable link-building report there is.
Toxic link detection and disavow support. Useful for spotting spammy patterns, though disavowing should be a last resort rather than a routine chore.
Monitoring and alerts. Links get removed, changed to nofollow, or buried. A tool that tells you when a link you earned disappears saves you finding out from a ranking drop.
Export limits. Check the row caps before you commit. A plan that shows you 100,000 referring domains but only exports 10,000 will frustrate any real audit.

The heavyweight link indexes

Ahrefs

Ahrefs is the default pick for serious link analysis, and the reason is the crawler. Ahrefs advertises an index in the region of 35 trillion live backlinks across billions of pages, and Site Explorer turns that into reports on referring domains, anchor text distribution, new and lost links, and link growth over time. If you are building a prospect list or reverse-engineering a competitor's campaign, this is the data set most agencies reach for.

Pricing runs from a Starter plan at $29 per month through Lite at $129, Standard at $249, and Advanced at $449, with an Enterprise tier at $1,499 per month on an annual commitment. The Starter plan is a genuinely useful entry point, but the row and credit limits mean anyone doing outreach at volume ends up on Lite or higher.

Semrush

Semrush pairs a large backlink database with a Backlink Audit tool that scores your profile for toxicity. It groups links by toxic markers, buckets your overall score as low, medium, or high depending on the share of suspicious links, tracks removal requests you have sent to webmasters, and builds an export you can upload to Google's disavow tool. That workflow, rather than raw index size, is the reason people pick Semrush for link cleanup.

Plans start at $139 per month for the SEO tier, then $199 for Starter, $299 for Pro+, and $549 for Advanced, with meaningful discounts on annual billing and a seven-day free trial. It is expensive if you only want links, and good value if you also need keyword research, rank tracking, and site audits in the same login.

Moz Pro

Moz Link Explorer remains the friendliest way into link analysis. Domain Authority and Page Authority give you a single 0-100 number for a site or a page, and Spam Score flags patterns associated with penalised sites, which makes triage fast for anyone who has never read a link report before. Just remember that Domain Authority is Moz's prediction of ranking strength, not something Google publishes or uses.

Moz sells Link Explorer as part of the Moz Pro subscription, positioned in the mid-market below the top Ahrefs and Semrush tiers, with a free trial and limited free queries available on a Moz account. Its published rates change often enough that the pricing page is the only figure worth trusting, so check it there rather than relying on a number in a roundup.

Majestic, the link specialist

Majestic does one thing. It has no keyword research module and no rank tracker, only backlink intelligence, and that focus shows in the depth of the archive. It publishes two indexes: a Fresh Index covering links found in roughly the last 120 days, and a Historic Index reaching back to 2006 that holds trillions of unique URLs. If you need to know what pointed at a domain three years ago, before a migration or an acquisition, Majestic is often the only tool that can answer.

Its metrics work as a pair. Citation Flow reflects the quantity of links pointing at a URL, and Trust Flow reflects their quality, based on proximity to a seed set of trusted sites. Reading them together is the point: a high Citation Flow with a low Trust Flow is the classic signature of a bought link profile. Plans start at $49.99 per month for Lite and $99.99 for Pro, with an API tier at $399.99, all excluding VAT.

Mid-market and budget options

SE Ranking has moved upmarket and now sits alongside the heavyweights on price, with Core at $129 per month and Growth at $279, both about 20 percent cheaper on annual billing and backed by a 14-day trial. What you get for that is a full suite that includes both a Backlink Checker and a separate Backlink Monitor, which is the better fit if your priority is watching an existing profile rather than mining new prospects.

The genuinely cheap end is now Serpstat, Ubersuggest, and SpyFu. Serpstat bundles backlink analysis into an all-in-one starting at $50 per month for the Individual plan, rising through $100 and $169 to $410 for Agency. Ubersuggest starts at $29 per month, with larger plans at $59 and $99 and a lifetime purchase option, and gives a simple backlink overview that suits a small site. SpyFu is the competitor-research pick, offering backlink searches alongside its ad-history archive from $39 per month, or $33 when billed annually.

Strong backlinks compound over time, which is one reason domain age and authority matter so much for SEO.

Free ways to check backlinks

Google Search Console is the only source that tells you what Google itself has discovered pointing at your site, and it costs nothing beyond verifying ownership. It is the ground truth for your own domain, though the sample it shows is limited and it will not touch a competitor.

Ahrefs Webmaster Tools, now presented as Ahrefs Free, gives verified site owners a slice of the paid product: up to 1,000 backlinks at a time in Site Explorer with the full sorting and filtering, plus Site Audit crawls against a monthly credit allowance. For a site owner who only needs to watch one domain, that combination covers a surprising amount of ground.

You can also cover the basics without a subscription using free web tools. A general-purpose backlink checker gives you a quick profile snapshot, a domain authority checker is enough to triage a prospect list, and an anchor text analyzer will show you whether your anchor distribution looks natural. None of these replace a paid index for competitive research, but they answer a lot of one-off questions.

How to run a backlink audit

Buying a tool is not a strategy. Here is the sequence that turns link data into decisions, whichever checker you land on.

Pull your full referring-domain list. Work at domain level first, not link level. A thousand links from one directory is one decision, not a thousand.
Sort by an authority metric and skim the extremes. The top of the list tells you what your best links look like so you can find more of them. The bottom tells you what needs investigating.
Check anchor text distribution. A profile dominated by exact-match commercial anchors is a risk signal. Branded and naked-URL anchors should make up most of a natural profile.
Screen the suspicious tail. Run questionable domains through a link quality analyzer before you act. Most low-authority links are simply irrelevant rather than harmful, and irrelevant links need no action at all.
Disavow only what is genuinely toxic. If you find a real pattern of paid or spam links you cannot get removed, build the file with a disavow file generator and submit it in Search Console. Disavowing healthy links does more damage than leaving spam alone.
Find the gap. Compare your profile against two or three rivals with a backlink gap analysis to list domains linking to them but not to you, then dig into individual rivals with a competitor backlink analyzer. This is where your outreach targets come from.
Fix what you are already losing. Run a broken link checker over your own site so that equity flowing in is not dead-ending on 404s.
Set up monitoring and repeat. Put your earned links into a backlink monitor so you hear about removals within days, and rerun the whole audit quarterly.

Frequently asked questions

What is the best backlink checker in 2026?

Ahrefs is the most common pick for overall link data quality, with Semrush close behind and stronger on the cleanup workflow. Majestic is the specialist's choice, particularly for historical data, and Moz Pro is the easiest starting point for beginners.

Can I check backlinks for free?

Yes. Google Search Console shows the links Google has found to your verified site, and Ahrefs Free lets verified owners pull up to 1,000 backlinks at a time in Site Explorer. Free web tools cover quick lookups. Deep competitor research still generally requires a paid index.

How many backlinks do I need to rank?

There is no fixed number, and any tool that implies one is selling you something. Quality and topical relevance matter far more than volume: a handful of links from trusted, relevant sites usually outweighs hundreds of low-quality ones.

Are Domain Authority and Trust Flow real Google metrics?

No. Domain Authority and Page Authority are Moz's own predictive scores, Trust Flow and Citation Flow are Majestic's, and every other authority number is likewise a vendor estimate. Google does not publish a public site-authority score. Use these metrics to compare candidates against each other, not as a verdict.

Why do two backlink checkers report different numbers?

Because each vendor runs its own crawler with its own budget, priorities, and refresh cycle, and each applies different rules about what counts as a live link. Differences of 30 percent or more between tools on the same domain are ordinary. Pick one tool as your baseline and track the trend rather than chasing the absolute number.

Should I disavow low-quality backlinks?

Usually not. Google states that in most cases it can assess which links to trust without extra guidance, so most sites will never need the tool, and its own advice is to get spammy links removed at the source first. Treat disavow as an advanced, deliberate step for a genuine paid-link problem or a manual action, not as routine hygiene.

The verdict

For most people Ahrefs offers the best backlink data, Semrush is the better buy if you want links alongside keywords and audits in one subscription, and Moz Pro is the friendliest starting point. Link specialists and anyone doing historical research will get more from Majestic than its price suggests. SE Ranking is the pick if monitoring an existing profile matters more than prospecting, and Serpstat, Ubersuggest, and SpyFu now hold the genuine budget end of the market.

Whatever you choose, remember that the checker is only the measuring instrument. The links still have to be earned, and a quarterly audit that actually changes what you publish beats a more expensive subscription you log into twice a year. Combine your pick with the keyword and audit tools in our full SEO tools guide for a complete workflow.
