Knowledge Graph
The Knowledge Graph is Google's database of billions of facts about people, places and things, drawn from public sources, licensed data and content owners. Some of what Google shows in its results comes from it, like quick answers to factual questions. Outside search, "knowledge graph" is also the general name for any database of connected facts.

What Knowledge Graph means for your business
You can't sign up for Google's Knowledge Graph or edit it directly. Google does take facts from people who claim a knowledge panel and suggest changes. So the work is making sure the public facts about your business are clear and agree with each other.
For a business, we'd start with your own site: an About page that says plainly who you are, plus Organization schema that links to your official profiles. Then we'd check your listings and profiles on other sites, so they all use the same name and the same short description.
Software teams build their own knowledge graphs to connect data, and plenty of articles about the phrase cover that meaning. When we say it, we mean Google's.
If Google or an AI tool mixes your business up with another one that has a similar name, helping search engines tell you apart starts with these same public facts.
