The Best Free Tools to Check Backlinks in 2025
There are more than a dozen reputable platforms where you can check backlinks for free — ranging from Google’s own webmaster tools to third-party SEO suites. Each tool has its own database size, data freshness, and feature limits. Below is a breakdown of the most trusted options, what they offer for free, and when to use each one.
How to Check Your Backlinks for Free Using Google Search Console
Google Search Console (GSC) is the most authoritative free backlink checker available — because the data comes directly from Google itself. It shows you every external link Google has discovered pointing to your site, which referring domains send the most links, and your most-linked pages. GSC is completely free with no daily query limits for verified site owners.
Follow these steps to access your backlink report in Google Search Console:
- Go to search.google.com/search-console and sign in with your Google account.
- Select your property (your verified website) from the dropdown at the top left.
- Click “Links” in the left-hand navigation panel (near the bottom of the menu).
- Review “External links” — here you’ll see your top linked pages, top linking sites, and top linking anchor text.
- Click “More” or “Export” under any section to download the full dataset as a CSV or Google Sheet for deeper analysis.
- Cross-reference your top linking domains against a free tool like Ahrefs or Moz to check the authority of those linking sites.
If your site isn’t yet verified in GSC, learn how to set up Google Search Console for your website — verification takes under 10 minutes.
“Backlinks remain one of the top three ranking factors used by Google. A single link from a high-authority domain can move the needle more than dozens of links from low-quality sites — which is why knowing who links to you matters as much as how many links you have.”

How to Check Competitor Backlinks for Free
Checking your competitors’ backlinks is one of the highest-leverage SEO activities you can do — it reveals exactly where they’re earning links so you can pursue the same sources. Since Google Search Console only shows data for your own verified domains, you’ll need third-party tools to analyze competitor link profiles. Fortunately, several platforms offer this for free.
Here’s how to run a free competitor backlink analysis:
- Identify 3–5 competitors ranking above you for your target keywords using a Google search.
- Go to Ahrefs Free Backlink Checker (ahrefs.com/backlink-checker) and enter a competitor’s domain.
- Review the top 100 backlinks shown — note the referring domains, anchor text, and DR (Domain Rating) of linking sites.
- Repeat with Ubersuggest for additional data points (3 free searches per day).
- Build a prospect list of sites linking to competitors but not to you — these are your highest-priority link-building targets.
- Prioritize by authority — target referring domains with a DR/DA above 40 first for maximum SEO impact.

Why Backlink Quality Matters More Than Quantity
Not all backlinks are created equal. According to Google’s PageRank algorithm, a link from a highly authoritative, trusted website passes significantly more “link equity” than dozens of links from low-quality or spammy sites. In fact, a study of over 11.8 million Google search results found that pages ranking #1 have an average of 3.8x more backlinks than pages ranking in positions #2–#10.
When reviewing your free backlink reports, look for these quality signals:
- Domain Authority / Domain Rating: Higher scores (50+) indicate more powerful links. For a deeper walkthrough, see our Checking Broken Links on a Website: Complete Guide.
- Topical relevance: Links from sites in your niche carry more weight than off-topic links.
- Anchor text: Natural, varied anchor text is healthy; over-optimized exact-match anchors can be a red flag.
- Do-follow vs. no-follow: Do-follow links pass SEO value; no-follow links are still valuable for traffic and brand visibility.
- Link placement: Editorial links within body content are more valuable than footer or sidebar links.
- Traffic of the linking page: A link from a page that actually receives visitors drives referral traffic in addition to SEO value.
💡 Pro Tip: If you find toxic or spammy backlinks pointing to your site, use Google’s Disavow Tool inside Search Console to tell Google to ignore those links. Free backlink checkers help you identify these harmful links before they damage your rankings.
Frequently Asked Questions
Can I check backlinks for free without creating an account?
Yes. Ahrefs’ free backlink checker at ahrefs.com/backlink-checker allows you to enter any domain and see the top 100 backlinks with no account required. Ubersuggest also offers limited free checks without signing up. For your own site, Google Search Console requires a free Google account but no paid subscription.
Is Google Search Console the best free backlink checker?
For your own site, yes — Google Search Console is the gold standard because it shows data directly from Google’s index, which is the search engine that matters most. However, GSC only works for domains you own and verify. For checking competitor backlinks or any domain you don’t own, Ahrefs’ free tool or Semrush’s free tier are better options.
How often should I check my backlinks?
For most websites, a monthly backlink audit is sufficient. If you’re actively building links, running a PR campaign, or have experienced a sudden rankings drop, check weekly. Google Search Console updates its link data roughly every few weeks, while third-party tools like Ahrefs crawl the web continuously and update more frequently.
Do free backlink checkers show all my backlinks?
No free tool shows 100% of your backlinks. Even Google Search Console doesn’t display every link — it shows a representative sample of the most significant ones. Third-party free tools show only a fraction of their full database (e.g., Ahrefs shows 100 links free vs. millions in the paid version). For a complete picture, combine GSC with at least one third-party tool, and consider a paid plan if backlinks are central to your SEO strategy.
What’s the difference between a backlink and a referring domain?
A backlink is a single hyperlink from an external page to your site. A referring domain is the unique website that hosts one or more of those backlinks. For example, if the New York Times links to you from 10 different articles, that counts as 10 backlinks but only 1 referring domain. Referring domains are a more meaningful SEO metric because Google values diversity of link sources — 100 links from 100 different domains is far more powerful than 100 links from a single domain.
If you’re asking where you can check backlinks for free, the answer is: start with Google Search Console for your own site’s data, then supplement with Ahrefs’ free checker and Ubersuggest for competitor research. Together, these three tools give you a comprehensive, cost-free view of your backlink landscape. Remember that backlink quality always outweighs quantity — a handful of authoritative, relevant links will outperform hundreds of low-quality ones. Make backlink auditing a regular part of your SEO routine, act on what you find, and your rankings will reflect the effort.
