Question 1

What is an llms.txt file?

Accepted Answer

llms.txt is an emerging standard (llmstxt.org) — a markdown file placed at the root of your domain that gives AI models a curated, machine-readable map of your most important pages, so crawlers like GPTBot, ClaudeBot, and PerplexityBot can understand your site without parsing full HTML.

Question 2

Where do I put llms.txt?

Accepted Answer

Place the file at the root of your domain so it resolves at https://yourdomain.com/llms.txt, the same location convention as robots.txt.

Question 3

What is the format of llms.txt?

Accepted Answer

It is markdown: an H1 with the site name, an optional blockquote summary, optional descriptive paragraphs, then H2 sections (Docs, Guides, Products) each containing a bullet list of links in the form - [title](url): optional note.

Question 4

How is llms.txt different from robots.txt?

Accepted Answer

robots.txt tells crawlers what they may not access; llms.txt tells AI models what matters and where to find it. They are complementary — robots.txt controls access, llms.txt curates understanding.
