AI Readiness is the umbrella concept; GEO Score is the measurement. A site can have great SEO and poor AI Readiness — classic symptoms are long unchunked narratives, missing llms.txt, and product pages that bury key attributes inside hero images.
The fastest path to AI readiness is, ironically, structural: cleaner headings, tighter paragraphs, explicit FAQ schema, and an inclusion list. Copy quality is second-order.
