Who's actually linking to you? Or to them.
Type a domain, get the real backlink profile: how many links, from how many unique domains, how much of it is trustworthy, and how much is risk you didn't know you had. Works for your own site, a competitor's, or a prospect's, whether or not it's a tracked project.
The moments this actually gets used.
New prospect, unknown site
- An agency needs a link profile fast, before the first call, with nothing set up.
A guest post offer lands
- Someone offers a link. Is the domain worth it, or is it a spam farm with a nice template?
Something changed, cause unclear
- Rankings slipped and a toxic backlink is one of several suspects worth ruling in or out.
Look up any domain's backlink profile in seconds, without adding it as a tracked project first.
Matches the domain against a live index of 7.5 trillion pages discovered and 44.7 trillion links tracked, and returns the profile directly, no crawl wait.
