Schema Markup

Schema Markup is a semantic markup system based on the standardized schema.org vocabulary, developed jointly by Google, Bing, Yahoo, and Yandex. It allows adding structured metadata to a page's HTML code to help search engines understand the context and nature of the content. The most common schema types include Article, Product, LocalBusiness, FAQ, HowTo, Event, and Review. Correct Schema Markup implementation can generate rich snippets in search results, significantly increasing click-through rate (CTR). JSON-LD is today the method recommended by Google for implementing structured data.
