What is Structured Data?

Also called: machine-readable data

In simple terms

Code added to a web page that labels its content in a standard format, so machines can understand exactly what the page describes.

Structured Data explained

Structured data describes page content in a standardised, machine-readable way. On the web it most commonly uses the Schema.org vocabulary in JSON-LD format, placed in the page’s HTML.

It helps search engines understand entities (organisations, people, products) and content types (articles, services, events), and it can make pages eligible for some rich results in Google.

Google requires structured data to reflect what users can see on the page. Google also states that no special structured data is required to appear in AI Overviews or AI Mode.

Structured Data: an example

A product page includes JSON-LD stating the product's name, price, currency and availability — the same facts shown visibly on the page.

Why it matters for search and AI visibility

Structured data clarifies entities and facts. It must match visible content, and it doesn't on its own earn placement in AI answers.
