llms.txt

llms.txt is an emerging convention - a file at the root of your site (like robots.txt) that points AI systems to your most useful, structured content in a clean, easy-to-read form. The idea is to help AI tools understand your site without wading through navigation, ads, and scripts.

Adoption is still early and support varies, but adding one is low-effort and forward-looking. It sits alongside the more fundamental question of whether AI crawlers are even allowed to read your pages in the first place.
