Schema Markup
Structured code you add to your pages to help search engines understand your content more precisely.
Schema markup is a standardized vocabulary of tags (from Schema.org) that you add to your HTML to help search engines understand your content. It tells Google not just what your text says, but what it means — turning unstructured content into structured data.
For example, without schema, Google sees "4.5" on your page and doesn't know if it's a rating, a price, or a version number. With Product schema markup, you explicitly tell Google "this is a product rating of 4.5 out of 5."
Schema.org defines hundreds of types: Person, Organization, Product, Article, LocalBusiness, Event, Recipe, FAQPage, HowTo, and many more. Each type has specific properties you can fill in to provide detailed information.
The most common implementation method is JSON-LD (a JavaScript format), though Microdata and RDFa are also supported. Google recommends JSON-LD because it's easiest to add and maintain without modifying your page's HTML structure.
Why It Matters for SEO
Schema markup is the key to earning rich snippets in search results. It helps search engines understand your content precisely, can improve your visibility in search, and provides the data needed for features like knowledge panels, carousels, and voice search results.
