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?
Adoption 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.
