What is Entity?

The short definition

An entity is a brand, product, person or concept that search engines and AI models recognize as one distinct thing, with a name, attributes and relationships to other entities.

When a language model or search engine meets a name, it doesn’t see a text string. It tries to resolve it into a known entity: who this is, what this is, how it relates to other things it knows. “Yaris” resolves to a car model, related to the Toyota entity, related to the fuel-efficient-cars category. The more confident that resolution, the more the system trusts what it knows about you.

A weak entity looks like this: the name appears in several variants, facts contradict each other across sources, and the context shifts from page to page. The model isn’t sure who you are, so it hesitates to cite you.

How it relates to SEO and GEO

The difference between a keyword and an entity is the difference between text and meaning: a keyword is what people type, an entity is what the system understands. GEO work builds a consistent entity: same name, same facts and same context everywhere models learn from, including schema, profiles and mentions. An entity the model recognizes and trusts is the entry ticket to answers, because models recommend what they’re confident about.
