llms.txt

A file at a site's root that guides AI crawlers to the pages worth prioritizing.

Modeled loosely on robots.txt and sitemaps, llms.txt gives AI systems a curated, human-readable map of your most important content and context. It helps models find and correctly represent your key pages when generating answers. Pairing llms.txt with a fuller llms-full.txt is an emerging GEO best practice.
