Check Your Site Backlinks Free

A backlink checker shows you which other websites point to yours, how strong those sites are, and which links might be dragging you down. This guide explains how to run that check with genuinely free tools, how to read the report line by line, and exactly what to do about every kind of link it surfaces.

What a site backlink checker actually does

A backlink is simply a link from one website to another. Search engines treat many of them as votes of confidence: when a respected site links to your page, it lends that page some of its credibility. Ahrefs describes backlinks as "trust signals or votes of confidence from other websites," and Google uses the surrounding anchor text to understand what your page is about.

A backlink checker crawls the web (or reads a pre-built index of it) and reports the pages that link to a domain you enter. No tool sees every link Google knows about, because no third party has Google's full index. That is why the honest approach is to cross-reference two sources: your own verified data inside Google Search Console, and one external crawler for the wider picture. If you want the underlying theory first, our complete guide to backlinks covers how link equity flows.

The free tools worth using

There is no 404Pulse backlink tool, and you should be sceptical of any blog that invents one. These are the real, free options, each with a genuine limitation:

• Google Search Console (Links report): free, and the only source that reflects links Google itself has recorded for your verified property. It lists top linking sites, top linked pages, and top anchor text. It does not score link quality.
• Ahrefs Free Backlink Checker: shows a capped sample of your top backlinks and a Domain Rating estimate without an account. Enough for a quick health read.
• Moz Link Explorer: a limited number of free queries per month, with its Domain Authority and Spam Score metrics.
• Ubersuggest: a small daily allowance of free lookups. For a fuller view of its limits and paid tiers, see our backlinks checker walkthrough.
• Bing Webmaster Tools: free, with its own backlinks report that sometimes surfaces links Search Console misses.

How to read the report without panicking

A backlink export can run to thousands of rows. Ignore the raw total. Focus on three signals per row:

1. The linking page and domain. Is it a real, topically related site, or an obvious link farm? Relevance and authority are what give a link value.
2. Authority. Domain Rating (Ahrefs) or Domain Authority (Moz) are third-party estimates, not Google numbers. Use them to compare links, never as an absolute grade.
3. Anchor text. Natural profiles show a mix of your brand, bare URLs, and descriptive phrases. A flood of identical commercial anchors ("cheap loans fast") is the classic footprint of a manipulated profile.

Google's own guidance on qualifying links explains the rel attributes you will see: nofollow is a hint, sponsored marks paid links, and ugc marks user-generated content. A followed link from a relevant, trusted page is the type worth celebrating.

Fixing what the checker finds

Sort every finding into one of four buckets and act only where it pays off.

Broken links pointing at your pages

If a strong site links to a URL on your domain that now returns a 404, you are wasting earned authority. Recover it: restore the page, or set a permanent redirect from the dead URL to the closest live equivalent. Google confirms that a 301 permanent redirect passes the signal on to the target. Our guide to broken links and their SEO impact covers the mechanics.

Lost links you want back

A link that disappeared usually means the linking page was deleted, edited, or moved. A short, friendly email to the site owner recovers more of these than people expect, especially when the link was editorial.

Toxic or paid links you did not earn

Google is far better at simply ignoring low-quality links than it once was, so most spam needs no action. Reserve the disavow file for a genuine, unnatural pattern (for example, a paid-link scheme you inherited). Disavowing good links by mistake does real harm, so treat it as a last resort.

Healthy links to leave alone

The majority of your profile. Do nothing except learn from it: note which content earned the best links and make more of that.

Mistakes that make a backlink check useless

Even with the right tools, it is easy to draw the wrong conclusions. Sidestep these traps:

• Treating one tool's count as the truth. Each crawler has a different index, so numbers will never match. Compare trends within a single tool over time, not raw totals between tools.
• Chasing quantity. A hundred links from unrelated directories are worth less than a handful from relevant, trusted sites. Google's John Mueller has said the total number of links is essentially irrelevant.
• Reading Domain Rating or Domain Authority as a Google score. They are third-party estimates. Useful for comparison, meaningless as an absolute grade.
• Disavowing on sight. Most spam is already ignored by Google. Reaching for the disavow file at every low-quality link does more harm than good.
• Checking once and forgetting. A single snapshot hides the trend. The value is in spotting change: new links, lost links, and newly broken targets.

Turning a one-off check into monitoring

Backlink profiles change constantly. Set a recurring review, monthly is plenty for most sites, and each time compare against last month:

• New referring domains: which content earned them?
• Lost links: worth a recovery email?
• New broken targets: any strong link now hitting a 404?
• Anchor-text drift: any sudden spike in identical commercial anchors?

Pair this with an authority check so you can see the trend, not just a snapshot. Our domain authority checker guide explains how to read those scores in context.

A simple monthly workflow

Put the pieces together into a routine anyone can follow:

1. Open Search Console, export the Links report, and note new top linking sites.
2. Run your domain through one free third-party checker for authority estimates and anchor text.
3. Flag any strong link pointing at a broken URL and fix it with a 301.
4. Send one or two recovery emails for valuable lost links.
5. Only if you see a genuine spam pattern, prepare a disavow file.

Fifteen minutes a month keeps earned authority working for you instead of leaking away.

Frequently asked questions

Can I check my site's backlinks completely free?

Yes. Google Search Console is free and shows the links Google has attributed to your verified site. Free third-party checkers such as Ahrefs Free Backlink Checker, Moz Link Explorer, and Bing Webmaster Tools add authority estimates and fill gaps, though each caps how much data it shows without a paid plan.

Why does each tool show a different number of backlinks?

Every checker has its own crawler and index, and none matches Google's full index. Search Console reports what Google recorded for your property, while third-party tools report what their own crawlers found. Treat the counts as directional rather than exact.

Should I disavow spammy backlinks?

Usually not. Google typically ignores low-quality links automatically, and disavowing good links by mistake can hurt you. Reserve the disavow tool for a clear, unnatural pattern such as a paid-link scheme, and leave ordinary spam alone.

What is the most important thing a backlink report tells me?

Which of your pages earn links and from where. That reveals your best content and your strongest relationships, and it flags valuable links now pointing at broken pages, which are the fastest wins to recover.

How often should I check my backlinks?

Monthly suits most sites. Backlink profiles shift as new links appear and old pages are removed, so a short recurring review catches broken targets and lost links while they are still easy to fix.
