Schema Markup is a standardized format for embedding structured data into web pages to enhance how search engines interpret and present content. It uses a shared vocabulary, primarily hosted at schema.org, to define entities, properties, and relationships on a webpage, such as products, events, articles, or organizations.
This markup does not change the visual appearance of a page but enables rich results in search engines—like featured snippets, star ratings, or event details—improving visibility and click-through rates. Implementation typically involves adding JSON-LD, Microdata, or RDFa annotations to HTML code, with JSON-LD being the most widely adopted format due to its simplicity and compatibility with modern web frameworks.
- Define entities such as products, events, or local businesses using schema.org vocabulary

Schema Markup is commonly used by SEO specialists, web developers, and digital marketers across industries including e-commerce, publishing, travel, and local services. Professionals skilled in this area are expected to understand basic HTML and JavaScript, interpret schema.org documentation, and troubleshoot structured data errors. Mastery of Schema Markup contributes to technical SEO proficiency and supports broader content discoverability goals.
