AI visibility (GEO/AEO)

What is Structured data (schema markup)?

Definition: Structured data is machine-readable markup (usually schema.org JSON-LD) added to a web page that describes its content — a product's price, an FAQ, an organization — so search engines and AI agents can understand and use it reliably.

Humans read your page; machines read your structured data. For commerce, schema.org Product and Offer markup tells AI shopping agents your price, availability and specs. FAQ and Organization markup feed AI answers and trust signals.

Generate it free with the Product schema and FAQ schema tools, then verify it's present with a scan.

What format should structured data use?

JSON-LD is the recommended format — a script block you add to the page, decoupled from your HTML. schema.org defines the vocabulary.
