Definition
Schema.org is a semantic markup vocabulary created jointly by Google, Bing, Yahoo, and Yandex to standardize how data is structured on the web. It defines hundreds of entity types (Article, Product, Organization, Event, FAQ, etc.) and their properties. By adding Schema.org markup to your pages (via JSON-LD, microdata, or RDFa), you help search engines better understand your content. This can trigger rich snippets in search results.
