Why robots.txt and llms.txt matter for AI crawlers
By Jahid Hasan
Robots rules set expectations; llms.txt helps route agents to the documents you want them to read first. Together they reduce ambiguity and accidental misuse.
robots.txt is the classic contract between your site and crawlers. For agents, it is still the first stop: it signals where to look next (like sitemaps) and what paths should be treated carefully.
llms.txt as a reading list
llms.txt is not magic SEO dust. Think of it as a curated reading list for language-model-oriented clients: what should be summarized, what is canonical, and where humans should still be in the loop.
Be explicit about intent
When signals conflict, agents guess — and guesses drift over time. Align your public documents with how you actually want data to be used, then measure whether your responses match that story under real fetch conditions.
