Free backlink checker
See what is building your website's authority.
Check referring domains, authority movement and a sample of the strongest domains pointing at your site, using Lumina's open-web graph.
What this backlink check can tell you
Who is pointing at you
See distinct referring domains and a sample of the strongest domains in Lumina’s open-web graph.
Whether the profile is moving
When two graph releases are available, Lumina separates newly seen and no-longer-seen referring domains instead of hiding the movement inside one total.
What needs deeper verification
A signed-in Lumina account can verify a bounded sample of actual archived source pages, anchors, follow state and current live status.
Backlinks are not the same as referring domains
One website can link to you many times. Referring-domain count asks how many distinct websites are represented, which is why Lumina shows both link evidence and domain-level breadth instead of treating raw link volume as authority by itself.
