Schema Markup
Schema markup is the implementation of structured data vocabulary (schema.org) on a web page to help search engines understand and display content in rich results.
Definition
Schema markup and structured data are often used interchangeably, but schema markup specifically refers to the code you add to a page that follows Schema.org's vocabulary. It is the practical implementation. Think of structured data as the concept and schema markup as the code. Over 800 schema types exist, covering everything from Articles and Products to Events, Recipes, FAQs, HowTos, and LocalBusiness.
Essential Schema Types for Most Sites
Every site should implement Organization schema (your business), WebSite schema (with SearchAction for site search), and BreadcrumbList schema. Content sites need Article or NewsArticle. E-commerce needs Product and Offer schemas. Local businesses need LocalBusiness schema. FAQ pages need FAQPage schema. Event pages need Event schema.
Testing and Validation
Use Google's Rich Results Test to validate your schema markup before deployment. Use the Schema.org validator for deeper debugging. Google Search Console's rich results report shows which pages have valid markup and surfaces errors. Schema that fails validation is ignored by Google.

Note
A common misconception: "more schema types = better rankings." Adding irrelevant schema (like Product schema to a blog post) can trigger manual actions. Only use schema types that accurately describe your content.
