llms.txt is a plain-text file you place at the root of your website that gives AI systems a curated map of your most important pages and content. Think of it as a friendly README written for language models rather than for people or search-engine crawlers.
How is it different from robots.txt and a sitemap?
The three files look similar but do different jobs. robots.txt says what crawlers may or may not access. A sitemap lists every URL so search engines can discover them all. llms.txt is editorial: instead of listing everything, it highlights the handful of pages and facts you most want an AI model to understand and cite, often with a short description of each. It is about emphasis, not completeness.
| File | Audience | Purpose |
|---|---|---|
| robots.txt | All crawlers | Access control (allow/disallow) |
| sitemap.xml | Search engines | Complete URL discovery |
| llms.txt | AI / language models | Curated map of your most important pages |
What goes in an llms.txt
The emerging convention (see llmstxt.org) is Markdown: an H1 with your site or company name, a short blockquote summary, then H2 sections grouping links with one-line descriptions. A fuller companion file, often called llms-full.txt, can include the actual content — service descriptions, FAQs, even current listings — so a model has the substance, not just the links.
Does llms.txt actually do anything yet?
The audience is already enormous: OpenAI reported ChatGPT reached roughly 300 million weekly active users by late 2024 (OpenAI, 2024 — and climbing since), so being legible to these systems matters more each month. That said, adoption of llms.txt itself is early and not every AI system reads it today, so treat it as a low-cost, forward-looking signal rather than a guaranteed ranking factor. It costs almost nothing to publish, it cannot hurt, and it documents your key pages in a machine-friendly way that is increasingly referenced. NameVerse publishes both an llms.txt and a fuller llms-full.txt.
A quick checklist
- Place
llms.txtat your site root (e.g.nameverse.net/llms.txt). - Lead with your name and a one-paragraph description of what you do.
- Group your highest-value pages under clear headings with short descriptions.
- Add a disambiguation note if other brands share your name.
- Keep it current as your key pages change.
