Limitation: this test appends a labelled marker to our own honest User Agent, it never impersonates another agent. Rules keyed to an exact User Agent string, or to a vendor's IP ranges, are invisible to this method and are neither confirmed nor ruled out.

AEO Watch is an independent, factual monitor. It is not affiliated with, endorsed by or speaking for any crawler vendor. Every statement is an observation with the date it was made and the raw evidence behind it: a robots.txt line, an HTTP status code, a header. There are no scores, no grades and no verdicts here, and nothing on this page is advice. A site opts out at any time and the opt out is honoured automatically and permanently.
