What is llms.txt and do I need one?

Short answer

llms.txt is a proposed plain-text file at the root of a website that gives AI tools a short, curated summary of the site and links to its most important pages. It is not an official standard and Google does not use it for search. It is cheap to add and harmless, but it will not fix weak content.

What goes in it

Typically a one-paragraph description of the business, followed by grouped links to key pages with a line explaining each: services, case studies, guides and contact details. The idea is to give language models a clean map of the site without navigating menus and scripts.

Should you bother?

If your site is small and well structured, the benefit is modest. Treat llms.txt as a tidy extra, not a strategy. The things that move AI visibility are still clear pages, consistent facts, structured data and third-party mentions. If you add one, keep it updated when services change, because an outdated summary is worse than none.
