Bot equals human: why search engines must see the same thing
The check requests the page twice — once with a search engine identifier, once with an ordinary one — and compares what comes back. If the two versions differ substantially, that's a finding.
- Deliberately delivering different content to search engines is a policy violation with harsh consequences. The unintentional case is more common: a protection mechanism treats the search engine's request as suspicious and delivers a block page.
- Also common: geographic redirects. A request from a data centre lands on a different language version than a request from the target country.
- The finding names the difference, not the intent. Whether it's a protective measure or deception, a measurement can't decide.
FAQ
Does a block page for bots already count as cloaking?
Technically, it delivers different content, and that's exactly what the check reports. Whether that counts as a violation depends on the specific case — either way, the consequence is that the page doesn't get indexed properly.
May we show logged-in users more?
Yes. Differences based on login state aren't cloaking. What's meant are differences that depend solely on the requester's identifier.
