What is Schema Markup? Complete Guide with Examples
Schema markup (structured data) is a standardized vocabulary of tags from Schema.org that you add to web pages to help search engines understand the content's meaning and context. By adding JSON-LD, Microdata, or RDFa markup, you enable rich results in search — star ratings, FAQ accordions, event dates, recipe cards, product prices, and more. Schema markup bridges the gap between human-readable content and machine-understandable data.

How Does Schema Markup Work?
Schema markup adds a layer of semantic metadata to web pages using JSON-LD (JavaScript Object Notation for Linked Data) scripts in the page's <head>. The markup describes entities (Person, Product, Article, FAQ) and their properties (name, price, datePublished) using the Schema.org vocabulary. Search engines parse this structured data to understand content context and can display enhanced results (rich snippets). Google's Rich Results Test validates markup, and Search Console reports which rich results are detected and any errors.

Common Use Cases
FAQ Rich Results
Adding FAQPage schema to pages with frequently asked questions can display expandable Q&A directly in search results, significantly increasing your page's SERP real estate and click-through rate.
Product Rich Results
E-commerce sites use Product schema to display price, availability, and review ratings in search results, making listings more attractive and informative compared to competitors without markup.
Local Business SEO
