Backlink Checker to Analyze Any Website's Link Profile

Enter a domain and see who links to it: backlinks, referring domains, top anchors, new and lost links over the past year, likely toxic and broken links, and a link gap against any competitor.

A backlink is a link from another website to yours. Search engines treat links from relevant, trusted sites as a sign that your pages are worth showing, so the sites that link to you shape how well you can rank.

A backlink checker shows which sites link to a domain, how strong those links are and how the link profile changes over time. It works for your own site and for any competitor's.

  • Enter a domain — Your own site or a competitor's. One check reads the whole domain's backlink profile.
  • Read the full report — Totals, referring domains, anchors, link history and link types come back together, in sixteen sections.
  • Spot the problems — See likely toxic links, links that land on broken pages, and the links you lost this year.
  • Find new links — Compare with any competitor to see which of their strongest linking sites you are missing, and browse directories that don't list you yet.
  • Backlinks & Referring Domains — Total backlinks, the number of unique sites linking to you, the dofollow share and an overall spam score.
  • Link Profile Strength — An authority score for the domain's link profile, so you can compare sites at a glance.
  • New & Lost Links — Links gained and lost month by month over the past year, with the cumulative total and your link velocity.
  • Top Referring Domains — The strongest sites that link to the domain, ranked so you see which links matter most.
  • Top Anchors — The twenty most-used anchor texts, so you can spot an unnatural pattern before it becomes a problem.
  • Top 100 Backlinks — The individual linking pages, with search and sorting, ready to export as a CSV file.

A backlink checker looks outward: who links to your site and how strong those links are. An SEO audit looks inward: the technical and on-page issues on your own pages.

Use both. Fix what the audit finds on your pages, then use the backlink report to earn the links that help those pages rank.

Check any domain's backlinks, catch toxic and broken links, and find the links your competitors have that you don't.
