What Is Schema Markup?
Schema markup is structured code, based on the Schema.org vocabulary, added to a page’s HTML to explicitly describe its content in a format search engines can read and interpret directly.
Common Types
Frequently used schema types include Article, Product, Review, FAQPage, HowTo, LocalBusiness, Event, and Recipe — each with fields specific to that content type, like price and availability for products, or cook time and ratings for recipes.
How to Add It
Schema is most commonly implemented as JSON-LD, a block of structured code placed in the page’s <head> or <body> that doesn’t affect visible content. Many CMS platforms and SEO plugins can generate common schema types automatically, though more specific or advanced markup often needs to be added manually or via a schema generator tool. Testing markup with Google’s Rich Results Test confirms it’s implemented correctly before relying on it.
