# Entity Type

> An entity type is the classification of an entity within a schema or knowledge system — the category that defines what kind of thing it is.

*Core concept* · *Entity & Knowledge Graph*

## Definition

An entity type is the classification of an entity within a schema or knowledge system — the category that defines what kind of thing it is. Schema.org defines a hierarchy of entity types including Thing, Person, Organization, LocalBusiness, Product, Event, and many subtypes.

## Why It Matters for AI Search

Getting the type right — and declaring it explicitly through schema markup — ensures the entity is evaluated against the correct set of attributes and surfaces in the correct query contexts. A LocalBusiness entity is evaluated differently than an Organization entity; a Product is handled differently than a Service. Incorrect or missing type declarations are a silent source of AI miscategorization.
