What llms.txt is and how to create it for your site

llms.txt is a Markdown text file published at the root of a site to summarize what the organization does and link its most important pages. It's designed so language models can find useful information without crawling the whole site.

What to include

A heading with the organization's name.
Un resumen breve entre comillas angulares (>).
Sections with links to the key pages and a description of each.

Does Google need it?

No. Google states that no special files are needed to appear in its AI features. Other assistants and agents can make use of it, and creating it takes minutes.

Where to publish it

At the root of the domain: yoursite.com/llms.txt. If your platform doesn't allow uploading files to the root, you can publish it as a page and redirect that address.
