Quick answer: Ahrefs’ free backlink checker lets you enter a domain or URL and see its top backlinks, referring domains, anchor texts and Domain Rating (DR). For deeper data on your own site, use Ahrefs Webmaster Tools, which is free once you verify ownership. Use the numbers to find link opportunities and risks, but remember that DR is Ahrefs’ own metric, not something Google uses.
Last reviewed October 21, 2026. Free-tool limits change, so confirm on Ahrefs. Details below come from Ahrefs’ own pages: free tools and Domain Rating.
What the free backlink checker shows
- The top backlinks pointing to the page or domain you enter (Ahrefs describes the top 100).
- Total backlinks and referring domains.
- Common anchor texts.
- Domain Rating (DR).
Ahrefs Webmaster Tools, free for sites you verify, adds a backlink overview, backlink reports, a crawl-based site audit and Search Console integration.
How to use it, step by step
- Enter a domain or URL into the free backlink checker, or add your own site in Ahrefs Webmaster Tools.
- Read the overview. Note total backlinks, referring domains and DR as a baseline.
- Look at referring domains first. Many links from one site count for less than links from many different, relevant sites.
- Check anchor texts. A natural profile has mostly branded and generic anchors. A long run of exact-match commercial anchors can look manipulative.
- Review new, lost and broken links. Lost links may be worth recovering, and broken links pointing to your site can be fixed with redirects.
- Study competitors. See who links to similar sites and ask whether you have a legitimate reason to be mentioned there.
- Repeat on a schedule and compare against your baseline.
Key metrics explained
| Metric | What it means | Caveat |
|---|---|---|
| Domain Rating (DR) | 0 to 100 score for the strength of a site’s backlink profile; logarithmic, so higher values are harder to gain | Ahrefs’ metric, not Google’s; formula is not public; it correlates with ranking potential but does not prove causation |
| URL Rating (UR) | Page-level strength | Same limits as DR |
| Referring domains | Unique sites linking to you | Relevance matters as much as count |
| Anchor text | The clickable words in a link | Over-optimized anchors can look unnatural |
| Dofollow vs nofollow | Whether a link is a standard or restricted-signal link | Per Ahrefs, nofollow links do not pass DR |
Good practice and what to avoid
- Earn links with useful content, original data and real relationships.
- Do not buy links or join link schemes. Google’s spam policies treat link spam as a violation.
- Do not chase DR for its own sake. Relevance and traffic from a link often matter more.
- Do not panic over a few odd links. Disavow is a last resort for clear manipulative patterns.
Alternatives
Semrush and Moz also offer backlink analysis, and Google Search Console shows links to your own site for free. Compare current pricing and limits on each vendor’s site. For lighter checks, see my notes on SmallSEOTools, and for planning content that earns links, read about content strategy.
Frequently asked questions
Is the Ahrefs backlink checker free?
Ahrefs offers a free backlink checker with limited results and free Webmaster Tools for sites you own. Full data requires a paid plan.
How often should I check my backlinks?
Monthly is enough for most sites. Check sooner if you run an outreach campaign or see an unexplained drop in traffic.
Does a higher DR mean higher Google rankings?
Not directly. DR is an Ahrefs score that correlates with ranking potential, but Google does not use it.
