Structured data

DefinitionStructured data is code on a page that states facts in a standard vocabulary (schema.org), so machines can read details like a product's price or an article's author without guessing.

Common types include Organization, Product, Review, Article, LocalBusiness, BreadcrumbList and FAQPage. Structured data makes pages eligible for Google rich results and removes ambiguity about facts such as your brand's exact name. It must match what the page visibly shows.

Google says structured data isn't required for its generative AI features and there's no special markup for them, but recommends it as part of normal SEO. See Structured data and llms.txt.
