Structured data is a standardized format (using schema.org vocabulary) to provide information about a page and classify its content. It helps search engines like Google understand the meaning of the page and enables rich results such as stars, images, and prices in search listings.

Our tool validates JSON-LD (JavaScript Object Notation for Linked Data) code snippets. You can paste any valid JSON-LD or an entire script tag. Microdata and RDFa are partially supported if they are converted to JSON-LD format first.

Each schema type has recommended and required properties. For example, a Product must have a name. Check the Schema.org documentation for your type and add the missing property to your JSON-LD. The tool will highlight missing critical fields.

Currently the tool only accepts pasted code. To extract structured data from a live page, use tools like Google's Rich Results Test or the Schema Markup Validator. For client-side testing, you can view the page source, copy the JSON-LD script, and paste it here.

Rich results are enhanced search listings that display additional visual or interactive features, such as star ratings, product prices, event dates, or recipe cooking times. They are powered by correct structured data on your page.
