Structured Data
Machine-readable labels added to a page that tell a search engine what its content actually is — a product, a recipe, a definition, a question and its answer.
Also known as schema markup JSON-LD rich results
Definition
A page of text looks like a page of text. Structured data — usually JSON-LD in the head — says "this block is the definition, this one is a question, this is the author".
That is what earns the richer search results: ratings, prices, expandable questions, and the answer boxes that quote a definition directly.
