Schema.org Structured Data
Quick definition
A shared vocabulary of structured data markup understood by Google, Bing, ChatGPT, Claude, and most AI agents.
What it actually means
Schema.org is a collaborative project by Google, Microsoft, Yahoo, and Yandex defining a standard JSON-LD vocabulary for marking up content meaning. The most-used types for eCommerce sites: Organization (brand identity), LocalBusiness (geo entity), Product (with offers, reviews), Article (blog posts), FAQPage (Q&A), HowTo (procedural), BreadcrumbList (navigation), and WebSite (with SearchAction). Proper schema implementation is the single highest-leverage SEO + AI optimization, often more impactful than additional content.
