Definition

A product entity is the structured representation of a specific product or service offering within a knowledge graph or schema system. In schema.org terms, it is an entity of type Product, which includes attributes such as name, description, brand, price, and availability, or Service, which includes name and description. Product entities matter for e-commerce and service businesses because they connect specific offerings to the broader brand entity in AI knowledge systems. A well-defined product entity — with accurate attributes, consistent naming, and schema markup — gives AI systems a structured reference for answering queries about specific products or services. For service businesses, implementing Service schema with clear descriptions and offerings is the equivalent of product schema for physical goods.
