Entity
A specific, named thing — a person, place, brand, product, or concept — that search engines and AI models recognize and understand as a distinct unit of meaning.
In SEO and natural language processing, an entity is a specific, named thing that search engines recognize as a distinct concept. Examples include people (Tim Cook, Marie Curie), places (Paris, Mount Everest), brands (Apple, Nike), products (iPhone, Tesla Model 3), and concepts (Generative Engine Optimization, photosynthesis).
Entities are different from keywords. A keyword is a string of text ("Tim Cook Apple CEO"). An entity is a specific, disambiguated concept in a knowledge graph (the person Tim Cook, who is the CEO of the company Apple). Google maintains a massive Knowledge Graph of entities and their relationships, and uses this to understand queries, rank pages, and generate AI Overviews.
Why entities matter for SEO in 2026
- AI Overviews cite pages that clearly identify and reinforce their entities.
- Knowledge Graph panels are built from entity data; pages that help Google understand entities may be cited.
- Topical authority is measured by entity coverage, not just keyword density.
- Disambiguation — a page about "Apple" the company should make it clear through context (named entities, structured data, schema) which Apple is meant.
How to optimize for entities
- Use named entities (people, brands, products) prominently and consistently.
- Add Organization, Person, and Product schema markup.
- Link to authoritative entity pages (Wikipedia, official sites, Knowledge Graph sources).
- Use first-person language where appropriate to establish Experience.
- Audit your page with an Entity Density Analyzer to see which entities Google will recognize.
