llms.txt
An emerging convention: a plain-text file at /llms.txt that tells AI crawlers which parts of your site are worth reading.
Think of it as robots.txt for AI engines but inverted. Rather than disallowing, you actively guide engines to the highest-signal content: product pages, comparison pages, founder bios, methodology pages. Most of the major AI crawlers haven't standardized on it yet, but the cost of shipping one is near zero and adoption is happening.
