Powered by a third-party backlink index. Figures are estimates and vary between providers.

How to Use This Tool

  1. Enter the domain whose link profile you want to size up.
  2. Select Check links to query the backlink index.
  3. Compare total backlinks against referring domains — diversity matters more than raw volume.
  4. Look at referring IPs to gauge how spread out the linking sources are.
  5. Treat the rank score as a relative comparison against competitors, not an absolute.

What Is a Backlink Checker?

Backlinks are links from other websites pointing to a domain, and they remain one of the strongest off-page ranking signals. This checker reports four figures: total backlinks (every link found), referring domains (the unique websites those links come from), referring IPs (the distinct IP addresses hosting them) and a rank score summarising overall strength.

The gap between backlinks and referring domains matters most. A thousand links from one site usually count for far less than a hundred links from a hundred sites, because diversity signals genuine, independent endorsement. Referring IPs add another layer: a wide spread suggests links come from many independent networks rather than a single private blog network, which search engines treat with suspicion. Read together, they show how natural and broad a link profile is.

No tool sees every link on the web, so all figures are estimates from a crawler's index and differ between providers. This tool is powered by a third-party SEO API that the site owner must configure with credentials; until then it shows a setup notice rather than numbers.

Frequently Asked Questions

What is the difference between backlinks and referring domains?
Backlinks count every individual link pointing to a site, while referring domains count the unique websites those links come from. Links from many different domains usually carry more weight than many links from one.
What does referring IPs mean?
It is the number of distinct IP addresses hosting the linking sites. A wide spread of IPs suggests a natural, diverse link profile rather than links from a single network.
Why is the data an estimate?
No tool sees every link on the web. The figures come from a third-party crawler's index, so they approximate the real profile and will differ between providers.
