What is Structured Data (Schema.org)?

A standardized vocabulary for marking up web content so search engines can understand and display it as rich results.

Schema.org provides a shared vocabulary (maintained by Google, Microsoft, Yahoo, and Yandex) for structured data markup on web pages. Common types include Product, Article, FAQPage, HowTo, Organization, BreadcrumbList, LocalBusiness, and Event. Implementation uses JSON-LD (recommended), Microdata, or RDFa embedded in HTML. Google uses structured data to generate rich results — star ratings, FAQ accordions, product prices, recipe cards, and event listings in search results. Rich results increase click-through rates by 20-30%. Google's Rich Results Test and Schema Markup Validator help verify implementations. Proper schema markup is a key SEO technique.
