ai.txt policy

ai.txt policy failed at "Validate transport".

62 Fail

Needs attention

ai.txt policy

Failed check
01

Issue

ai.txt appears to be an HTML page or error document rather than a plain-text policy.

02

Why it matters

ai.txt is a fragmented emerging convention. It can communicate human-readable AI crawling, training, attribution, restriction, and contact guidance, but it is not a standard access-control mechanism and absence should not be penalized.

Category

Bot Access Control

Maturity

Emerging recommendation

Goal

Publish an advisory human-readable AI usage policy only when the site intentionally needs one.

Result

ai.txt policy failed at "Validate transport".

Validation steps

  1. Validate transport

    ai.txt appears to be an HTML page or error document rather than a plain-text policy.

  2. Parse ai.txt policy

    Transport validation failed before policy parsing could be trusted.

  3. Validate policy content

    ai.txt does not follow the AI Visibility section model; treating it as non-standard advisory text.
