Question 1

What is an llms.txt file?

Accepted Answer

llms.txt is a proposed standard file that a website places at its root, like yoursite.com/llms.txt. It gives AI assistants and large language models a clean, markdown-formatted map of the site: a short summary of what the site is, followed by sections of links to the most important pages, documentation and resources, with brief notes on each. The idea is that an AI tool can read one tidy file instead of crawling and guessing its way through a whole website.

Question 2

Does having an llms.txt file improve my SEO or AI visibility?

Accepted Answer

Honestly, it is not a ranking factor today, and no major search engine has promised to use it. What it does do is make your best content easy for AI tools to find and quote correctly when they do look at your site, in the same spirit as a sitemap for search crawlers. Adoption is growing among documentation sites and developer tools, and the file costs you ten minutes to create, so many site owners treat it as cheap, sensible preparation rather than a guaranteed traffic source.

Question 3

What is the difference between llms.txt, robots.txt and a sitemap?

Accepted Answer

They do three different jobs. robots.txt tells crawlers which parts of the site they may or may not visit. A sitemap lists every page you want indexed, for search engines. llms.txt is a curated shortlist written for AI language models: fewer links than a sitemap, chosen by importance, in markdown, with a human-written summary and notes explaining what each link is. The three files sit side by side at your site root and do not conflict.

Question 4

What should I put in my llms.txt file?

Accepted Answer

Start with your site name as the title and a one or two sentence summary of what the site does. Then add sections for the content an AI assistant would need to answer questions about you: product or service pages, documentation, pricing, key guides, API references and support pages. Give every link a short note saying what the reader will find there. Leave out login pages, checkout flows, legal boilerplate and anything you would not want quoted.

Question 5

What is the Optional section in llms.txt?

Accepted Answer

The specification reserves a section literally named Optional for links that an AI may skip when it needs a shorter context, such as secondary resources, archives or nice-to-have extras. Put your must-read pages in the regular sections and the lower-priority links under Optional, so a tool working with limited space drops the Optional links first instead of guessing.

Question 6

Where do I put the generated llms.txt file?

Accepted Answer

Upload it to the root of your domain so it loads at yoursite.com/llms.txt, the same place as robots.txt. It must be publicly reachable as plain text or markdown. After uploading, run it through an llms.txt validator to confirm the structure is correct, and update it when you add or retire important pages.
