A knowledge graph is a structured network of entities and the relationships between them, such as a brand connected to its founders, products, industry, and location. Google's Knowledge Graph and open sources like Wikidata are the best-known examples, and AI systems draw on this kind of structured knowledge to reason about the world.
For brands, presence in a knowledge graph helps AI systems understand who you are and place you correctly in your category. A complete, accurate Wikidata item, a populated Google Knowledge Panel, and consistent facts across the web all strengthen your position in these graphs, which in turn makes it easier for an AI to describe and recommend you confidently.
