What is structured data?

Structured data is webpage content marked up using Schema.org vocabulary, helping search engines better understand pages. Common formats include JSON-LD, Microdata, and RDFa. Proper markup can earn Rich Results like star ratings, FAQ accordions, and breadcrumbs.

How do I validate structured data?

Paste your JSON-LD code and click Validate. The tool checks JSON syntax, verifies @context and @type fields, and detects known Schema types like Article, Product, FAQPage, etc.

What's the difference between JSON-LD and Microdata?

JSON-LD is Google's recommended format. It uses a JSON object in a script tag, separate from HTML structure, making it easy to maintain. Microdata is embedded directly in HTML attributes. This tool primarily validates JSON-LD.
