What is the Google Knowledge Graph?

Google introduced the Knowledge Graph in May 2012 with more than 500 million objects and more than 3.5 billion facts about and relationships between them. It lets Search answer questions about things directly, rather than only matching the words in a query to the words on a page, and it supplies the knowledge panels that appear for well-known people, places, and organizations.

There is no form for adding a business to the Knowledge Graph. Google builds it from sources it trusts: consistent information across the web, public databases, and for local businesses, the details in their Google Business Profile. The practical work for a business is making sure those sources agree, with the same name and the same description everywhere, and structured data on its own site that points to its real profiles.
