Google Knowledge Graph
Google Knowledge Graph is Google's structured-data database of real-world entities — people, organizations, places, products — and the relationships between them. Introduced in 2012, it powers Knowledge Panels (the entity cards on the right side of SERPs) and feeds entity-recognition systems used by Google Search, AI Overviews, and Gemini.
In depth
Entity confidence matters more than keyword density for brand-name visibility. A new domain ranking for its own brand name depends on Knowledge Graph recognizing the brand as a distinct entity.
Inputs Google uses to add entities: Wikipedia presence, Wikidata entries, Google Business Profile (highest single signal for local businesses), Crunchbase, LinkedIn Company pages, schema.org Organization markup with sameAs links to verified profiles.
Knowledge Graph entries take 2-6 months to consolidate for new entities. Faster with multiple independent third-party citations (3+ recommended threshold).
Brand search rankings improve dramatically once an entity is in the Knowledge Graph — typically position 30+ → position 1-3 within 1-2 weeks of entity recognition.
Common misconception
You can't directly submit an entity to the Knowledge Graph. Google extracts entities automatically from authoritative third-party sources. The fastest path is creating a Google Business Profile + Crunchbase + LinkedIn Company + Wikipedia (when notable enough) — Google consolidates them into a single entity.
