From an overseas check point we look at crawler access, static readability, structured data, the accessibility tree and real-user performance. Every conclusion comes with its evidence and its limits — and no overall score.
No account, no email, no phone number. Each result gets a permanent link you can share.
It is free and needs no account. No email, no phone number. Each run produces a permanent link you can share with a colleague or client.
Crawler access via robots, static readability, structured data, the accessibility tree and real-user performance, plus whether each AI crawler can fetch the page on its own. The deep pass also runs a user-agent differential matrix and WAF vendor fingerprint, which separates "the site has no content" from "the site blocks crawlers at the door".
An overall score blends prerequisites, outcomes and guesses into one number that looks precise but cannot be acted on. This tool reports pass rates per group and states the limits of each finding underneath it, so you can see why something was judged that way and what it does not imply.
The light pass returns in about half a minute. The deep pass and the probe stage run in the background in parallel and usually complete within a few minutes, on the same permanent link — you can close the page and come back.
Testing an overseas site from mainland China changes latency, the TLS handshake and which CDN edge answers; some sites also apply regional policies to mainland IPs. An overseas check point is closer to where ChatGPT, Claude and Perplexity actually fetch from.
No. The deep pass visits with the browser's default identity so the site does not serve different content because it detected a crawler. Performance and real-user data come from Google PageSpeed Insights.
Visitors are identified by a salted hash; raw IP addresses are never stored. The checked URL and its results are kept so the permanent share link keeps working.
