Free tool
Free Backlink Checker
See who links to any domain
Creates a free account with 1,000 credits — no card, and the result is waiting when you land.
Why this needs an account
Every one of these numbers is bought from a data provider per request. A checker that answered anonymously would be a bill anyone could run up, so instead you get a free account with real credits and the answer comes out of those. No card, and nothing expires on a timer.
The same credits open every other tool too, which is usually the more useful discovery.
The full tool
Every link pointing at a target, with its source page, anchor text, target URL, dofollow status and quality signals. Start on one link per referring domain to cut the noise, then expand any domain to see the rest.
