How does Google’s Knowledge Graph work?
It is Google's structured database of entities (people, places, organizations, things) and the relationships between them. It powers Knowledge Panels, AI Overviews, and most entity-driven search features.
The Knowledge Graph (Google’s structured database of entities and how they relate) is Google’s structured map of the world: a database of distinct entities and the relationships between them, rather than a list of pages. When Google is confident enough about an entity (who a person is, what a company does, how they connect to other entities) it draws on the Graph to generate the Knowledge Panel, populate AI Overviews, and power the entity features that increasingly frame a search result before the user reads a single link. For reputation work this matters because the Graph is upstream of so much of what people see. It is fed by sources Google trusts to define entities: Wikipedia, Wikidata, official websites with schema markup (structured tags that tell search engines what a page is about), and authoritative third-party references. Influencing what the Graph believes about an entity means improving those underlying sources, which is the entity layer of a reputation program. We track how an entity renders across Google with IMPACT™, because the Knowledge Graph’s read on a client is now the foundation the rest of the result is built on.
