llms-txt

Adoption verdict: llms-txt is reasonable to try for a public documentation, knowledge-base, or content site that wants to expose a clearer reading entry for language models. For now, it is better treated as a low-cost information-architecture experiment than as required growth infrastructure. The official GitHub project supports the basic idea of a file intended to help language models use website content, but the supplied evidence does not show that major models consistently read it or that publishing it reliably increases traffic, citations, or rankings.

Its practical role is to place a /llms.txt file at the site root and organize important pages into a machine-readable map, generally using Markdown or plain text with site guidance, page groupings, and links. A more accurate analogy is a website directory or reading guide for models. It is not an SEO ranking tool, not robots.txt, not a crawler-permission controller, and not an AI-traffic switch. It cannot replace crawl access, clear source content, technical quality, or normal search and content work.
