Context
Cloudflare’s announced defaults take effect for new domains: Training and Agent traffic is blocked by default on ad-supported pages while Search remains allowed; multi-purpose crawlers are governed by their most restrictive applicable purpose.
What changed
Blocking training can also affect multi-purpose crawlers that combine search and training behavior.
Why it matters
A publisher’s AI policy can now directly influence discoverability, agent access and potentially conventional search access when crawler purposes overlap.
Visibility OS interpretation
An actionable technical-GEO milestone: crawler policy must be audited as part of AI visibility.
What remains uncertain
No event-specific uncertainty note is recorded yet. This record may change as new evidence is reviewed.
