Structured Data and Schema

Machine-readable markup that tells search engines and AI systems what a page's content actually represents.

What Structured Data and Schema is

Schema.org vocabulary expressed as JSON-LD labels entities and their properties — an article, an organisation, a course, a defined term — so machines do not have to infer them from prose.

How it works

A JSON-LD block declares the type and properties, matching what is visible on the page. Markup that contradicts visible content is a policy violation and can be penalised.

Why it matters

It is the cheapest way to make content unambiguous for both search engines and retrieval systems that feed AI answers.
