What is Structured Data?
Machine-readable metadata embedded in a webpage using formats like JSON-LD (preferred), Microdata, or RDFa. Structured data speaks Schema.org, a shared vocabulary that tells search engines and AI models exactly what your content is: an Article, a Person, a FAQ, an Event, a Product, and so on.
My perspective
In practice
Implemented as JSON-LD scripts in the page <head>. Each schema type unlocks specific capabilities: FAQPage → accordion rich results; Article → news and Discover carousels; Review → star ratings in SERPs; BreadcrumbList → breadcrumb display; Person → knowledge panel entity recognition. This site uses 7+ schema types across its pages.
