THE SIGNAL
What this visit tells you
Ad review traffic belongs to campaign operations. Counting it as organic AI discovery would inflate acquisition reporting.

Review-time errors
Your next move
Match a visit to a submitted landing page and its review window before interpreting traffic as campaign demand.
The technical details
MarkdownHow to identify it
Look for the OAI-AdsBot identifier in a request’s User-Agent. This is a name match, not identity verification. Version strings may change.
How to check identity
Compare the request IP with the current operator-published ranges linked in the source. A matching name alone does not verify identity.
Access and robots.txt
The source describes submitted-ad review; no robots.txt behavior is asserted here.
Seeing 403 or 404 responses?
403 means access was denied; 404 means the resource was not found. Compare the public path, request time, edge security event and origin response to find the cause.
Separate intended restrictions and secret-file probes from pages that should work. A User-Agent name alone does not justify allowing a request.
