About This Tool

Inspect structured-data markup and identify common schema or syntax issues before publishing a page. Use the results as a development aid alongside Google's current structured-data documentation.

How to Use It

Provide the page or markup supported by the validator, run the check and review reported properties and syntax issues. Correct the source markup and validate it again.

How It Works

Structured data gives search engines machine-readable information about page entities and properties. Valid syntax does not guarantee a rich result, because eligibility depends on the feature and Google's policies.

Practical Example

A product page may contain product properties but omit a required or recommended field for a specific search feature. Correcting the markup improves machine readability, while eligibility remains separate.

Frequently Asked Questions

Does this guarantee production correctness? No. Validate important results in the actual browser, application or search environment.

Can automated validation replace expert review? No. It identifies detectable issues but context and platform-specific requirements still matter.
