Why it matters
They may help systems that choose to consume the convention retrieve cleaner context and navigate important documentation.
How to use it
Publish a root /llms.txt with curated links, keep canonical HTML available, maintain mirrors with the same facts, and prevent duplicate search results when appropriate.
Limits and interpretation
Google says it does not use llms.txt or special AI files for Search rankings or generative AI inclusion. The convention is optional and not a standard ranking factor.
Common mistakes
Publishing stale mirrors; hiding different content in Markdown; claiming Google benefit; placing every low-value URL in llms.txt; blocking the canonical HTML.
