What is Structured Data?

Structured data is standardized Schema.org markup (usually JSON-LD) that describes a page's content to search engines, helping them understand it and, when eligible, show rich results.

Also known as: Schema Markup · Schema.org Markup · JSON-LD

Why it matters

It makes page content machine-readable, improving how engines interpret entities and enabling rich results and clearer citations in AI answers.

Who needs it

Any site that wants richer search appearances (FAQs, breadcrumbs, articles, products) and clearer understanding by search and AI systems.

When it's used

Add relevant, accurate markup as pages are built or updated, and only for content that actually appears on the page.
