The Four Files Nobody Links To
Every website has four plain-text files no visitor ever sees: robots.txt, sitemap.xml, security.txt, and llms.txt. Search engines, security scanners, and AI agents read them on every visit.
What each one is, who actually reads it, what to put in it, and the one rule that keeps all of them safe. We went through this list on our own site this week and found gaps, so the free audit now checks for them.
