A structured database used by search engines to store and connect entities and their attributes, powering rich results and answer experiences.
A Knowledge Graph is a system for storing entities (people, places, businesses, concepts) and the relationships between them. Google’s Knowledge Graph supports features like knowledge panels, entity understanding, and improved relevance. In practice, stronger entity signals help search engines (and AI systems) trust and reuse your information.
Knowledge Graph optimisation is less about tricks and more about making your business unambiguous and verifiable.
