Schema markup is structured data added to a web page's HTML using JSON-LD (or other formats) that provides additional context to search engines about the content on the page. It uses the Schema.org vocabulary and can describe businesses, articles, FAQs, products, events, reviews, and more. Schema markup can trigger rich results in Google Search, such as star ratings, FAQ dropdowns, and breadcrumbs, which increase click-through rates.
