Free tool
Score any site against the Five Signals.
Paste a URL. We fetch it, parse it, and grade it on the five signals AI platforms read before quoting a result. You get a score for each signal and a plain-English fix list. No sign-up. No email.
We do not store the URLs people check. No login required. The checker fetches your site once and discards the response.
