Backlink Checker
Analyze any website's backlink profile. See total backlinks, referring domains, dofollow ratio, spam score, and link type distribution.
How to use this backlink checker.
Backlinks remain one of Google's top 3 ranking factors. Understanding your backlink profile - and your competitors' - is essential for any SEO strategy. Use this tool to audit link quality, identify toxic links to disavow, and benchmark your domain authority against competitors.
Focus on the referring domains count rather than raw backlink numbers. A site with 100 links from 80 unique domains will almost always outrank a site with 1,000 links from 10 domains. Breadth of endorsement matters more than volume from a single source.
Quality over quantity
10 links from authoritative, relevant sites outweigh 1,000 links from low-quality directories. Focus your link building on earning editorial mentions from real publications.
Monitor your spam score
If your spam score is above 30, audit your backlinks for PBNs, hacked sites, and irrelevant foreign-language links. Consider submitting a disavow file to Google.
Dofollow ratio matters
A natural link profile has a mix of dofollow and nofollow links. A 70-80% dofollow ratio is typical. An unnaturally high dofollow percentage can look manipulative to Google.
Fix broken backlinks
Broken backlinks are wasted link equity. Set up 301 redirects for any URLs that have moved, or reach out to linking sites to update the URL.
Frequently asked questions.
What are backlinks?
Backlinks are links from other websites that point to your site. They act as votes of confidence in search engine algorithms - the more quality backlinks a page has, the more likely it is to rank well in Google. Not all backlinks are equal; links from authoritative, relevant sites carry far more weight than links from low-quality or unrelated sites.
What is a referring domain?
A referring domain is a unique website that links to your site at least once. If site A links to you 50 times, that still counts as one referring domain. The number of unique referring domains is generally a stronger ranking signal than the raw backlink count, because Google values breadth of endorsement over repetition from a single source.
What's the difference between dofollow and nofollow?
Dofollow links pass PageRank (link equity) to the target page, directly helping its rankings. Nofollow links include a rel="nofollow" attribute that tells search engines not to pass ranking signals. While nofollow links don't directly boost rankings, they still drive referral traffic and contribute to a natural-looking link profile.
What does spam score mean?
Spam score is a metric (0-100) that estimates how likely a site's backlink profile is to be penalized by Google. A high spam score suggests many links come from low-quality, spammy, or PBN-like sources. Scores under 30 are generally healthy; above 60 warrants a backlink audit and potential disavow file.
How can I get more backlinks?
The most sustainable strategies are: creating link-worthy content (original research, tools, comprehensive guides), digital PR and outreach, guest posting on relevant authoritative sites, broken link building, and earning editorial mentions through expertise. Avoid buying links or participating in link schemes - these tactics risk Google penalties.
