Schema.org is the collaborative vocabulary for structured data markup, maintained by Google, Microsoft, Yahoo, and Yandex. It defines the types, properties, and relationships that can be expressed in structured data markup — from Organization and Person to LocalBusiness, Article, FAQPage, and hundreds of other entity types.
Schema.org is the shared language that structured data speaks. When a brand implements schema markup, it is declaring its entity type and attributes using schema.org vocabulary — the same vocabulary that AI systems and knowledge graphs use to understand entities. Using schema.org types correctly connects a brand’s structured data to the broader semantic web that AI systems draw from.
