*Core concept* · *Entity & Knowledge Graph*

## Definition

An entity graph is a network of entities and the relationships between them — representing how people, organizations, places, products, and concepts are connected within a knowledge system. Google's Knowledge Graph is the most prominent example of an entity graph at web scale.

## Why It Matters for AI Search

An entity graph is how AI systems understand context beyond individual facts. A brand that exists as a node in an entity graph — connected to its industry, its founder, its location, its products, and its competitors — has a richer, more stable AI representation than a brand that exists in isolation. Building entity graph presence means creating and maintaining the relationships between your entity and the surrounding ecosystem of entities it legitimately connects to.
