Does Google use llms.txt?

No. Google has said it does not use llms.txt in Search or in AI Overviews, so the file has no effect on visibility in Google.

How is llms.txt different from robots.txt?

The robots.txt file tells crawlers which URLs they may fetch, while llms.txt neither blocks nor allows anything – it is a summary of the site with links to its key pages. Access for AI bots is still controlled in robots.txt.

Is it worth adding llms.txt to a website?

As a simple extra, yes, since it takes little time to prepare. Just do not expect a traffic boost from it – there is no evidence that AI search tools choose sources based on it.

llms.txt

Site summary file for AI

llms.txt is a Markdown file at the root of a website that briefly describes the site and points language models to its most important pages.

Official site

What is llms.txt?

llms.txt is a proposed standard for a Markdown file served at /llms.txt that summarises a website and links to its key pages for large language models. It is not a search engine standard and there is no guarantee that any AI system reads it – Google has said it does not use the file in Search or in AI Overviews. It is best treated as an optional extra rather than a visibility mechanism.

How we use it at Koda Plus

On koda.plus we maintain our own llms.txt: a description of our services with links to the offer, the technologies we use, frequently asked questions, company details and a short summary in English. In AEO projects we treat it as an optional extra, not a substitute for work on search-agent access, structured data and content.
