llms.txt
llms.txt is a plain-text file at a site's root that gives AI assistants a curated map of its most important pages, similar to how robots.txt and sitemap.xml help search crawlers.
It lists your key URLs with short descriptions so an assistant can find your products, collections, policies, and articles without crawling everything.
It's an emerging convention, not a guaranteed ranking factor — but it's cheap to publish and increasingly looked for by AI tools.
