Knowledge Graph
A structured database of entities and the relationships between them, used by search and AI systems to represent real-world facts.
How it differs from a webpage index
A knowledge graph does not store pages — it stores facts and relationships, such as which company makes which product or who founded which organization, which a model can draw on directly rather than inferring from text.
Why getting into one matters
A brand represented accurately in a major knowledge graph has a verified, structured record of its identity that AI systems can reference directly, rather than relying solely on unstructured mentions scattered across the web.
Examples
Google's Knowledge Graph and Wikidata are two prominent examples. Both represent entities as structured nodes connected by defined relationships — founder-of, headquartered-in, manufacturer-of — rather than as pages of text to be parsed.
