llms.txt generator: create the file without guesswork
The Rankmetr llms.txt generator builds an llms.txt file from the key pages of your website and checks it against the proposed format. The tool is in early access: leave your website and we will tell you when it opens. One honest note first: the effect of llms.txt on visibility in search and AI answers is not proven.

What is an llms.txt file?
llms.txt is a proposed standard: a plain text file in Markdown that sits at the root of a website, at yoursite.com/llms.txt. It gives large language models and AI agents a short guide to the site: what it is about and which content is most important, with a clean URL for each page. Think of it as a table of contents written for machines, a bit like docs for developers.
A typical llms.txt file in Markdown has an H1 with the site name, a short summary in a blockquote, and sections with H2 headings and lists of links, each with one line of description. Some sites also publish llms-full.txt with the full text of key pages. It is optional.
What the llms.txt generator does
The goal is a file that is short, correct and easy to keep up to date.
- Collects key pages: the tool reads your website and suggests which URLs belong in the file.
- Writes the structure: builds the H1, the summary and sections with links and one-line descriptions.
- Checks the format: works as an llms.txt checker: headings, link syntax, each URL that returns an error or a redirect.
- Gives an example to edit: you get a ready llms.txt example for your site to review before you publish it.
Is llms.txt actually used?
Here the honest answer matters more than a sales pitch. llms.txt is not an official web standard. Google has said that it does not use the file. Other AI companies have not confirmed that their systems read it when they build answers. So there is no proof that an llms.txt file improves rankings or visibility in AI answers.
Why create it anyway? The file is cheap: it takes little time, it does not change how search engines crawl or rank your site, and it gives a clean summary of your content that can help you too, for example as context for ChatGPT or another AI assistant. For SEO and AI search optimization, crawler access and structured data are more important, so treat llms.txt as a small extra.
llms.txt best practices: publish and maintain
- 01
Review the draft
Make sure the summary describes your business in plain words and the pages are the right ones.
- 02
Upload to the root
Place the file at the root URL /llms.txt so the browser shows it as plain text.
- 03
Keep robots.txt in order
llms.txt does not replace robots.txt or the sitemap. Check AI crawler access with the robots.txt checker.
- 04
Update it
When key content changes, generate the file again so links do not break.
Where llms.txt fits in GEO
Visibility in AI answers depends mostly on the content models find about you on the web: your pages, reviews, directories and articles that mention you. A file at the root of your site is a small part of that work. Structured data helps AI tools and search engines understand your pages, so check it with the schema validator. For a full plan, see GEO.
