llms.txt Validator
We fetch the origin's llms.txt and count real links. A paragraph of brand copy with one homepage link is a brochure.
What this check covers
- HTTP success and a non-empty body
- Length vs a thin-file threshold (~120 characters)
- Markdown or raw http(s) links
Read it honestly
- Experimental / emerging: treating llms.txt as a ranking factor. We do not.
- Confirmed: the file is fetchable and either is or is not a map.
Questions
Do I need llms.txt?
If you care about answer engines that look for a URL map, yes. It is not a substitute for robots, schema, or indexable HTML.
