A clean entry point to your site for AI models

llms.txt is a standard text file placed in the root of the site and directs AI models to your most important content in a clean, easy-to-read format. The goal is to make it easier for generative systems to understand and cite your site. llms.txt is a relatively new, evolving standard inspired by the idea of robots.txt, but aimed at large language models. This article explains what it is, what it looks like, and how to create it.

llms.txt: what it is and how to create it

What is llms.txt?

llms.txt is a plain text file (in Markdown format) that lives at an address like yoursite.bg/llms.txt. In it, you briefly describe what your site is about and provide links to the key pages and resources that you want AI systems to use as a source. The idea is to offer them a structured, clean entry point to the content instead of relying on extracting it from full HTML pages.

What does an llms.txt file look like?

The structure is simple: a title with the site name, a short summary, and thematically grouped links. Example outline:

A line with the title — the company or site name.
A short summary sentence about what you offer.
Sections with links to the main pages — services, guides, key resources, each with a brief description.

The file is for machine reading, so the value lies in clarity and organization, not design.

How do you create llms.txt?

Gather the key pages. Choose your most important services, guides, and resources.
Write short descriptions. One clear sentence per link.
Save the file as llms.txt in Markdown.
Upload it to the root of the domain. Important here: this requires server access (FTP or administration), not just access to the content editor. If you do not have such access, the task should be assigned to the site administrator or developer.

Is llms.txt mandatory?

No. It is an emerging standard and adoption by different AI systems still varies. It is not a replacement for good, structured content and technical accessibility — rather, an addition. It is useful as a clear signal, but on its own it does not guarantee citation.

Frequently asked questions

Is llms.txt the same as robots.txt?

No. robots.txt tells bots what to crawl and what not to; llms.txt directs AI models to the key content and presents it in a clean form. The two files serve different purposes and can exist at the same time.

Will AI cite me as soon as I add llms.txt?

Not automatically. The file helps, but citation depends on the overall structure, authority, and accessibility of the site.

llms.txt is one of the six directions in GEO. The full picture is in the guide „What is GEO optimization“, and we can set it up for you through the service GEO optimization.

Често задавани въпроси

What is llms.txt?

llms.txt is a plain text file in Markdown format that lives in the root of your site, for example at yoursite.bg/llms.txt. It gives AI models a clean, structured entry point to your most important content by briefly describing your site and linking to key pages and resources.

What should an llms.txt file contain?

An llms.txt file usually includes your site or company name, a short summary of what you offer, and thematically grouped links to the main pages you want AI systems to use. Each link should have a brief description so the file is easy for machines to read and understand.

How do I create llms.txt?

First gather your most important pages, such as services, guides, and key resources. Then write one clear sentence per link, save the file as llms.txt in Markdown, and upload it to the root of your domain. This usually requires server access such as FTP or administration access.

Do I need server access to add llms.txt?

Yes, adding llms.txt typically requires server access, not just access to the content editor. If you do not have FTP or administrative access, the task should be given to the site administrator or developer so the file can be placed in the root of the domain.

Is llms.txt mandatory?

No, llms.txt is not mandatory. It is an emerging standard, and support across AI systems still varies. It can be a useful addition, but it does not replace structured content or technical accessibility on the site.

Is llms.txt the same as robots.txt?

No, they serve different purposes. robots.txt tells bots what to crawl and what not to crawl, while llms.txt directs AI models to your key content in a clean, organized format. The two files can exist side by side.
