What is Schema.org Structured Data?
Schema.org is a structured-data vocabulary jointly maintained by Google, Bing, Yahoo, and Yandex. Once annotated via JSON-LD, search engines and AI models can directly understand whether a page is an Article, Product, FAQ, or Organization — powering rich results and precise citations.
How do you apply it in practice?
Five types every GEO site needs: Article, FAQPage, HowTo, Organization, BreadcrumbList. Always add @id and sameAs to reinforce entity consistency.
Why does it matter for AI search citations?
Generative search engines tend to extract sentences that are clearly defined, consistent and quotable on their own. Writing concepts like "Schema.org Structured Data" as one consistent definition across your site, backed by structured data and verifiable sources, lowers the chance of being misread. This improves readiness only; it does not guarantee citations or ranking gains — measure actual citations to know.
