Knowledge Graph

The Knowledge Graph is Google's semantic database that stores information about entities (people, places, organizations, concepts) and their relationships to each other. Since 2012, it has revolutionized how Google understands and answers search queries.

Core Functions of the Knowledge Graph

The Knowledge Graph operates on three main levels:

Entity Recognition - Identification of entities in search queries
Relationship Mapping - Linking between different entities
Contextual Understanding - Understanding search context and intent

Knowledge Panel - The Heart

The Knowledge Panel is the visual representation of the Knowledge Graph in search results. It typically appears to the right of organic search results and provides structured information about an entity.
