crawler classification

The model edge providers adopted in 2026, Cloudflare from July with new-domain defaults changing on 15 September: verification confirms only who a crawler is, and access is then decided per behaviour class, Search, Agent, or Training, rather than per operator. A multi-purpose crawler is judged under every class it belongs to, which is how a rule that blocks Training can block a search crawler that also trains.

What crawler classification means

It is the industry name for the identity-versus-permission distinction that verified crawler already implies.

What crawler classification does not show

The classes are the provider's judgment of a crawler's purpose, and that judgment is not published in a form a site can audit.
