A schema type is a specific class within the schema.org vocabulary — such as Article, FAQPage, Product, Organization, LocalBusiness, or Person — that defines the type of entity or content being marked up. Each schema type has a defined set of properties and expected values.
Schema type selection determines what entity information can be expressed and how AI systems interpret a page’s content. Choosing the most specific applicable schema type — Restaurant rather than LocalBusiness, SoftwareApplication rather than Product — provides AI systems with more precise entity classification and unlocks type-specific properties that broader types do not support. Schema type decisions are the first step in any structured data implementation.
