Structured data
Also known as: schema markup, JSON-LD
What is structured data?
Structured data is machine-readable markup — usually JSON-LD following schema.org — that states explicitly what a page is about: article, product, FAQ, organisation, author. Search engines and AI models use it to interpret and attribute content.
Schema does not rank a page by itself. Its value is removing ambiguity: which entity published this, when it was updated, who wrote it, and which question each section answers.
