Optional llms.txt Check
Understand FreeScan's informational check for an optional llms.txt or .well-known/llms.txt resource.
Check your websiteWhy this check matters
An llms.txt file can provide supplemental machine-readable navigation, but it is not a standard requirement and does not determine AI-search eligibility. FreeScan scores it as informational only.

HTTP 404 at /llms.txt and /.well-known/llms.txtPossible false positives
- Not having llms.txt is not an SEO failure.
- A file can exist while containing stale or unsupported claims.
How to fix it safely
- Only add the file when it can be maintained accurately.
- Link to canonical public resources rather than duplicating entire pages.
- Avoid presenting the file as a replacement for crawlable HTML or structured data.
How to verify the fix
- Request both supported locations and confirm the intended file returns plain text.
- Review every referenced URL for accuracy and public accessibility.
