JSON-LD

JSON-LD is a JSON-based format for linked data, embedded in a script tag, and the format search engines recommend for schema.org markup.

It keeps markup separate from presentation, so it survives design changes better than microdata.

For AEO, the most useful types are Organization, Article, FAQPage, Product and BreadcrumbList.
