Schema.org
The shared vocabulary of types engines understand — Organization, FAQPage, DefinedTerm and more.
What is schema.org?
Schema.org is a shared vocabulary of types and properties — Organization, Product, FAQPage, DefinedTerm and more — that search engines and AI engines understand. It is the standard language for expressing structured data on the web.
Schema.org is the dictionary of structured data: the agreed set of words engines use to recognise what a piece of content is.
Founded by the major search engines, schema.org defines a hierarchy of types (Thing, Organization, CreativeWork, FAQPage, DefinedTerm) and the properties each can carry. When a page uses these types, every consuming engine interprets them the same way — a shared contract between publisher and machine.
For AEO/GEO, schema.org is the vocabulary you mark content up in. Choosing the right type — DefinedTerm for a glossary entry, FAQPage for Q&A, Organization for the brand — tells engines precisely how to file and cite the content. It is the meaning layer; JSON-LD is the syntax that carries it.
SkuLift uses schema.org types throughout: DefinedTermSet on the glossary hub, DefinedTerm on each card, FAQPage on answers, Organization and Service across the site — a deliberate, vocabulary-correct AEO foundation.
