Method: each site's homepage was scored 0–100 by our free agent-readiness checker across six machine-readability signals — structured data (JSON-LD), llms.txt, llms-full.txt, author markup, sameAs entity links and markdown alternates. A high score means an AI agent can read and cite the site; a low score means it's a brick wall to the engines writing AI answers.
