Entity

An entity is a concept or object that search engines and AI models can recognize and connect with others, forming the basis for semantic search.

What is an entity?

An entity is a distinct and well-defined concept or object, such as a person, place, organization, product, or idea, that search engines and AI can uniquely identify and relate to other entities. Entities go beyond simple keywords by representing real-world subjects with specific attributes and relationships. This allows search systems to understand meaning and context instead of merely matching text strings.

Entities enable several important functions:

• Form the basis of semantic search and knowledge graphs
• Allow search engines to grasp connections between concepts and provide relevant results
• Enable systems to differentiate between different meanings using context (e.g., "Apple" as a company vs. a fruit)
• Assist search engines and AI in accurately identifying and showcasing content through clear entity signals

Optimizing content with clear entity signals—using structured data, consistent naming, authoritative references, and contextual relationships—helps search engines and AI systems accurately identify and present your content when users search for related topics.
