Schema markup
Also known as: Structured data
Schema markup is structured code added to a web page that helps search engines understand its content and display rich results.
Schema markup is a standardized vocabulary (from schema.org) added to a page's code to label what its content means — that this text is a product, a review, an FAQ, or a definition. It does not change what users see directly but tells machines how to interpret the page.
Properly marked-up pages can earn enhanced search listings (rich results) and are easier for AI systems to parse and cite. It is a foundational technical SEO practice for surfacing in modern, answer-driven search.
