Technical implementation · Entity & Knowledge Graph
Definition
A subgraph is a subset of a larger knowledge graph focused on a specific entity or topic domain — used by AI systems to reason about relationships within a bounded context. A brand’s entity subgraph includes the brand entity, its associated people, products, locations, and topics, and the relationships between them.
Why It Matters for AI Search
Building a rich entity subgraph means establishing not just the brand’s own entity record but the network of verified relationships around it — founder entities with Person schema, product entities with Product schema, location entities with geographic associations. The denser and more accurate the entity subgraph, the more context AI systems have for accurate brand characterization across a wider range of queries.
