llms.txt is a proposal for a simple file at the root of a website that gives AI systems a concise overview of the site. According to public statements by Google representatives in 2025, there is no confirmation that major search engines or AI systems use it as a signal. You can have it because it is cheap, but a strategy should not rely on it.
What llms.txt is
It is a plain text document in Markdown format that lives at yourdomain.com/llms.txt. In it you state who you are, what you offer, which pages are key and your contact details. The idea is that an AI system gets a tidy picture of your company in a single request without reading the whole website.
The proposal appeared in 2024 as a community initiative, not as an official standard set by any body.
Does anyone use it
According to public statements by Google representatives in 2025, Google does not use llms.txt, and as far as they know, none of the major AI systems use it for ranking or choosing sources. Some tools and developers read the file when explicitly pointed to it, but that is not the same as the recommendations AI assistants give ordinary users.
The situation may change, so it is wise to check the news from time to time. As of the publication date of this article, there is no reliable evidence that llms.txt increases the number of recommendations.
Is it worth it anyway
Creating the file takes an hour or two and costs nothing, and the downside is negligible. It is also useful as an exercise: it forces you to write clearly who you are, what you do and how much it costs. You can use that same summary on your About page and in your profiles.
What probably brings more are the foundations: clear service pages, public prices, schema.org markup, consistent company data, reviews and media mentions.
What to put in the file
- The company name and a short description in one or two sentences.
- A list of key pages with links and a one sentence description.
- Prices or a link to the pricing page.
- Contact details and links to official profiles.
- The date of the last update.
DigiAdria has an llms.txt on its own website for exactly these reasons: as a cheap add-on and a good summary of the company, but we do not claim that it alone increases the number of recommendations in AI answers.
Frequently asked questions
Will llms.txt increase traffic to my website?
There is no evidence for that. Treat it as an add-on, not a replacement for quality content and technical soundness.
Is llms.txt the same as robots.txt?
No. Robots.txt tells crawlers what they may read. Llms.txt is a descriptive summary and is not a tool for permissions or bans.
Do I need llms.txt for AI assistants to recommend me?
No. It is not known to be a prerequisite. Content, evidence and consistency of data matter more.
