What is llms.txt?
llms.txt is a plain Markdown file at the root of a website (yoursite.com/llms.txt) that gives AI systems a short summary of the business and a curated list of its most important pages. It follows the proposal published at llmstxt.org.

llms.txt is a proposal, not a standard the major assistants have committed to reading, so treat it as a low-cost, low-risk addition rather than a ranking lever. Its value is that it states your business and your key pages in the plainest possible form for any system that does read it. It does not replace robots.txt (which controls access) or structured data on your pages.
How to publish one
- Write the file (keep it short: the pages that matter, not every URL).
- Serve it at the root of your domain as plain text, at /llms.txt.
- On supported platforms, NextEO's AutoFix can generate and serve it for you, and the technical audit grades an existing one.
