Structured data (schema.org)

Machine-readable markup, usually JSON-LD, that describes a page's entities such as products, reviews, FAQs, and organisations.

Definition

Structured data uses schema.org vocabulary to state what a page is about in a form search engines and assistants can parse: a software application with ratings, an FAQ with questions and answers, an article with author and date. Linked entities via identifiers help systems connect pages to real-world things.

Why it matters when choosing a tool

Structured data improves rich results and gives AI systems reliable facts about your content, supporting both SEO and GEO.
