This page reports how many observations moved, by check and by observation. It never names a domain that started or stopped allowing a crawler. A change is a fact about one site's own file, and publishing a named list of them would be a list of accusations; the counts are the useful part and the only part we publish.

Check your own site
The same checks, run on your domain now: what robots.txt tells each AI crawler, whether the edge answers them, and whether the text is readable without JavaScript. Free, no signup.
Limits: 8 checks and 5 different domains per address per hour; a repeat of the same domain inside 7 days is answered from what we already hold.
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.
