What is llms.txt and does my business website need it?
llms.txt is a plain-text file at yoursite.com/llms.txt that summarizes your site for language models: who you are, what you offer and which pages matter. It is a proposal, not a standard every assistant reads.
What goes in it
- A title and one-line summary, then short sections with links to your key pages, written in Markdown (llmstxt.org).
- Your services, area and contact details
- Links to your most important pages: services, pricing, FAQ, about
Does it matter?
Not every assistant reads it yet, so it carries the smallest weight in AEO Pro’s score: 2 of 100 points. Crawler access, readable content and structured data matter far more (see the AI-readiness checklist). It costs little to add.

Questions
Is llms.txt the same as robots.txt?
No. robots.txt tells crawlers what they may fetch. llms.txt is a summary to help AI tools understand your site.
Will llms.txt get me into ChatGPT answers?
On its own, no. It is a small help. Crawler access and clear pages matter much more.
