Knowledge graph

Knowledge graph is a database used by Google and other search engines to provide structured information about entities such as people, places, organizations, and other topics. It enhances search results by showing detailed, factual information directly on the SERP, often in a panel or box.

For example, if you search for "Albert Einstein," the Knowledge Graph might display a panel with details about the entity, such as his photo, birthdate, scientific achievements, and related topics, without requiring further clicks.

The Knowledge Graph organizes and connects data about entities, helping search engines understand their relationships. For instance, it links Albert Einstein to related entities like "Theory of Relativity" or "Nobel Prize in Physics."

Entities included in the Knowledge Graph often come from trusted sources like Wikipedia, Wikidata, and authoritative websites. By providing accurate and structured information, websites can increase their chances of being featured.

Optimizing for the Knowledge Graph involves using structured data, such as schema markup, to define entities on your website. A strong website architecture and well-organized URL structure also make it easier for search engines to crawl and interpret your content.

The Knowledge Graph is especially impactful for zero-click searches, where users get their answers directly on the SERP. For brands or businesses, being recognized as an entity in the Knowledge Graph builds authority and improves visibility.
