Google’s database of entities and their relationships, powering knowledge panels and much of AI search.
The Knowledge Graph is Google’s vast database of entities — people, places, companies, things — and the relationships between them. It is what powers the knowledge panels you see on the right of many results, and it lets Google answer factual questions directly rather than just listing links.
You influence what Google knows about your entity by feeding it consistent, authoritative signals: structured data, a strong Wikipedia/Wikidata presence where warranted, consistent information across trusted profiles, and clear "about" pages. For brands and notable people, earning a knowledge panel is a visibility and trust win — and it starts with being an unambiguous, well-referenced entity.
The Knowledge Graph is the backbone that AI Overviews and LLM answers lean on for grounded facts, so entity presence in it increasingly determines whether you are cited. Senior practitioners treat knowledge-graph inclusion as a long-term authority project — building the corroborating references across the web that the graph draws from — rather than a schema quick-fix, and they monitor how their entity is represented as a brand-risk surface.
