Definition
Structured data markup is machine-readable code, usually JSON-LD, that explicitly labels what your content is: an FAQ, an article, a product, an organization. It helps both traditional and AI engines interpret and index a page correctly.

How Structured Data Markup / Schema.org Works
Schema.org is the shared vocabulary for those labels. Add it and you tell engines, in their own language, "this section is a list of FAQs," or "this is the author." The page looks the same to a human, but machines understand it far more precisely.
Why Structured Data Markup / Schema.org Matters
When an engine knows exactly what each part of your page is, it can use those parts with more confidence, like pulling your FAQ answers straight into a response. Markup is one of the most direct ways to make content easy for AI to read and extract.
