Schema Markup
Structured data using Schema.org vocabulary, usually expressed as JSON-LD, that tells AI systems and search engines what type of content a webpage is and what it contains.
Also known as: JSON-LD, schema.org markup, structured data markup
Schema markup is structured data that uses the Schema.org vocabulary to describe the content of a webpage in a way that machines can reliably interpret. It is typically expressed in JSON-LD format, embedded in the HTML head element. Schema markup can describe the type of content (Article, FAQPage, Product, Organization), the author, publication date, topic, relationships to other entities, and much more. For AI systems, schema markup answers the question: what is this page? ... explicitly and without requiring inference from the page's visual content or prose.
