Schema markup for AI search: a 2026 reference

Schema markup tells search engines and AI engines what a page is about in a structured, parse-friendly form. For AI search in 2026, the highest-value types are FAQPage, HowTo, Article with citation references, DefinedTerm, Dataset, and Organization. Several Google-era types (Recipe, Event, Review) still matter for Google but contribute little to AI citation. This guide is the working reference Crawlmind uses to score schema for AI discoverability.
