The Knowledge Graph is Google's vast database of real-world entities and the verified facts and relationships connecting them, powering features like knowledge panels, rich snippets and much of the entity-level understanding covered in our entity-based SEO guide.
Google compiles Knowledge Graph data from a combination of structured data sources (Wikidata, Wikipedia, verified business listings), publicly available structured data on individual websites (via schema markup), and its own algorithmic analysis of information across the web.
A knowledge panel is the visible box, often appearing alongside search results for a recognised entity, summarising key facts — for a business, this might include hours, address, social links and a brief description, drawn directly from Knowledge Graph data.
A knowledge panel is not something you apply for directly — it is Google's confident summary of an entity it has already recognised clearly, based on signals accumulated over time.
There is no direct submission process for most businesses to request a knowledge panel — panel appearance follows from Google's own confidence in an entity's recognition, built through the consistent, verified signals above, rather than something requested or purchased directly.
No, there is no paid or direct request mechanism for most businesses — panel appearance is algorithmic, based on Google's confidence in the entity's recognition and notability.
No, panels tend to appear for entities Google has recognised with sufficient confidence and, often, some degree of notability or searcher demand — many smaller, purely local businesses primarily rely on their Business Profile instead.
No, Wikidata is a separate, structured database of facts (without prose articles) that Wikipedia and other services, including Google's Knowledge Graph, can draw from — it has its own, somewhat different notability and sourcing standards.

Focus on consistent structured data and verified profile claims (Business Profile, social platforms) rather than chasing a knowledge panel directly — panel appearance follows from strong entity signals, not the reverse.
