What is Schema Markup?
Structured data code added to web pages that helps search engines understand content and display rich results.
Schema Markup Explained
Schema markup is a standardized vocabulary of tags (from Schema.org) that you add to your HTML to help search engines understand the meaning and context of your content. It translates human-readable content into machine-readable data. For example, schema markup can tell search engines that a page contains a product with a specific price, an article by a specific author, a recipe with cooking time, or an FAQ with question-answer pairs. The most common implementation format is JSON-LD (JavaScript Object Notation for Linked Data), which is added as a script block in the page head. Proper schema markup enables rich snippets in search results and can improve content visibility and click-through rates.
