Schema Markup
Also known as: Structured Data
Structured data vocabulary (from Schema.org) that helps search engines understand page content. Review, Product, and FAQ schema can generate rich snippets in search results.
What does Schema Markup mean?
Schema markup is a standardized vocabulary, maintained by the Schema.org collaboration between major search engines, that structures page content in a machine-readable format search engines can parse directly rather than inferring meaning from unstructured text. It comes in specific types such as Review, Product, and FAQPage.
Why does Schema Markup matter?
It matters because it is the technical mechanism that unlocks rich snippets and other enhanced search features; without correctly implemented markup, a page's star ratings or pricing information stay invisible to search engines even if they are clearly visible to human visitors.
How is Schema Markup applied in practice?
It is implemented as JSON-LD code embedded in a page's HTML, validated using search engine testing tools before launch, and its real-world impact is measured through search console data showing whether rich results actually begin appearing and whether click-through rate from search improves as a result.
