Cloudflare enables opt-out of AI training while preserving search indexing

Cloudflare is introducing a new feature that allows website owners to differentiate between content indexing for search engines and content usage for AI training. Starting September 15, 2026, websites can opt out of AI training while still allowing search engine crawlers access, addressing a significant portion of web traffic that was previously blocked entirely if AI training was disallowed. This new control, integrated into Cloudflare's security settings and communicated via robots.txt or HTTP headers, also includes a separate option to manage access for AI agents acting on behalf of users. AI

IMPACT Allows websites to control AI training data usage without sacrificing search engine visibility, potentially impacting AI model development and search engine optimization strategies.
