Knowledge Graph
A structured database of entities (people, places, things) and their relationships, used by search engines to disambiguate.
Full definition
A knowledge graph is a structured representation of real-world entities and the relationships between them. Google's Knowledge Graph powers entity panels, Gemini grounding, and a growing share of AI Overview citations. Your brand's presence in the Knowledge Graph is a major GEO signal.
Brands clearly resolved in the Knowledge Graph get cited more often and with higher confidence. The fastest paths in: Organization schema with sameAs links to Wikipedia, Wikidata, Crunchbase, and verified social profiles.
Example
Wikidata Q-numbers (e.g. Q95 = Google) are the canonical entity identifiers in the open knowledge graph.

Is Knowledge Graph the same as SEO?
No. Knowledge Graph is one piece of the broader GEO (Generative Engine Optimization) program that sits on top of classical SEO. The two work together — classical SEO gets you crawled and indexed; Knowledge Graph is part of what gets you cited by AI engines.
Do I need a tool to implement Knowledge Graph?
For most teams, a free scanner like OptimAIze is enough to identify what's missing. Implementation is usually a copy-paste of generated markup or a small code change — no specialist tool required.
