Schema Markup (Structured Data)

Definition

Schema markup is structured data vocabulary (from Schema.org) that you add to your web pages to help search engines understand the meaning of your content. When implemented in JSON-LD format (Google's recommended approach), it enables rich results in search — star ratings, FAQs, how-to steps, business hours, product prices, and more. Pages with rich results see 20-30% higher click-through rates on average. Common schema types include LocalBusiness, FAQPage, HowTo, Product, Article, Organization, and BreadcrumbList. Use Google's Rich Results Test to validate your markup after implementation.
