Backlink checker questions
What is a backlink?
A backlink is a link from another website to yours. Search engines treat links from relevant, trusted sites as votes of confidence, so backlinks are one of the strongest ranking signals.
Backlinks or referring domains — which matters more?
Referring domains. Ten links from ten different sites usually count for more than a hundred links from one site. Watch both, but grow the number of referring domains.
What does dofollow mean?
A dofollow link passes ranking value to the page it points to. Nofollow links (marked rel="nofollow", "ugc" or "sponsored") still bring visitors but pass little or no ranking value.
Is it really free?
Yes. You can run 3 free checks a day without an account. Create a free account when you need the full backlink list, referring domains, anchor texts and exports.
