Structured data is machine-readable metadata added to a web page — typically as JSON-LD in the head — that describes the page's content using a shared vocabulary such as schema.org.

Google's structured-data introduction recommends JSON-LD. Common types: Article, QAPage, FAQPage, Organization, Person, BreadcrumbList.
Structured data is machine-readable metadata added to a web page — typically as JSON-LD in the head — that describes the page's content using a shared vocabulary (schema.org) so search engines and answer engines can understand what the page is about beyond raw text.
JSON-LD (JSON for Linking Data) is a W3C-standardized JSON syntax for encoding linked data — it lets a web page declare structured metadata inline using vocabularies like schema.org, and it is Google's recommended structured-data format.
Schema.org markup affects AI citations indirectly but reliably — it collapses the model's attribution problem by making the author, publisher, and answer text machine-readable, and it is the primary signal Google uses to render both classic rich results and the source strip in AI Overviews.
Use FAQPage schema when your site publishes an official multi-question answer page authored by your team, and use QAPage when the page is a single user-submitted question with community-submitted answers — Google's structured-data guides define the two types precisely and enforce the distinction.
