llms.txt explained: the AI-readable summary of your website
llms.txt is a small text file that hands AI systems your most important facts in a clean, unambiguous form. Think of it as a concise briefing an AI can read without wading through your whole site.
At a glance
llms.txt is a plain-text (Markdown) file at the root of your domain. It summarizes who you are, what you offer and links to your key pages, so AI systems pick up your core facts correctly instead of guessing. It is quick to add and complements (does not replace) crawlable HTML and structured data.
What is llms.txt?
llms.txt is an emerging convention for a file at /llms.txt that gives large language models a curated, machine-readable overview of your site. Instead of letting an AI infer your identity from scattered pages, you state it directly: name, what you do, for whom, and links to the pages that matter.
Why it helps
AI systems summarize and cite based on what they can clearly extract. A focused llms.txt reduces guesswork: it gives the model a reliable anchor for your key facts and points it to the right pages. It is part of GEO/AEO, making your content easy for machines to understand and reuse.
What belongs in it
- A title and one-line summary of who you are and what you do.
- A short paragraph with the essentials: offering, audience, what makes you relevant.
- Links to key pages grouped by section (product, docs, about, contact), each with a short description.
