Use this when someone asks whether AI engines can read, crawl or quote their website, or wants an AI-readiness audit of a site. Runs eight checks: AI crawler access in robots.txt, llms.txt, Organization and FAQ schema, canonical and meta tags, server-rendered copy, and whether an about page and a pricing page exist. It does not measure whether any engine actually cites the site; check_ai_visibility does that. No AI call, nothing stored.
