Schema Markup
Schema markup is structured code added to a page that tells search engines what its content means, enabling rich results and AI understanding.
Schema markup is vocabulary from Schema.org added to your HTML, usually as JSON-LD, that labels content explicitly — this is a product, this is a price, this is a FAQ, this is an article. Search engines read it to understand your page beyond raw text. The payoff is rich results: star ratings, FAQ accordions, breadcrumbs, and event details that make your listing stand out and earn more clicks.
Schema is now foundational for AI and answer engines, which rely on clear structure to extract and cite facts confidently. Marking up entities, definitions, and Q&A content makes your information machine-readable and quotable. Pages with accurate schema are easier for generative engines to trust and reuse, making it a quiet but powerful lever for both classic SEO and GEO.
