llms.txt is the fastest machine-access win in GEO, and most enterprise sites still do not have one.
Think of it as robots.txt and a sitemap for AI crawlers: a plain text map that tells engines who you are, what you do, and where your best, most citable content lives. It removes the guesswork that keeps you out of answers.
