Schema Markup Checker
Enter a page URL to retrieve its structured data and review the schema items detected in the returned markup.
Results will appear here after the check runs.
Detection or valid syntax does not guarantee rich-result eligibility. Client-rendered markup may require a rendered-page test.
How to Use Schema Markup Checker
- Enter the public absolute URL containing the structured data.
- Run the check and review detected formats, types, properties, and parsing messages.
- Compare the markup with visible page content and validate required properties with the relevant official rich-result test before deployment decisions.
Structured Data Detection Versus Eligibility
Schema.org vocabulary can be expressed with JSON-LD, Microdata, or RDFa. A checker can report detected syntax and entities, but search features apply additional required properties, content policies, and quality rules.
A successful parse does not guarantee a rich result, and an undetected item can result from client-side rendering or unsupported markup. Inspect rendered HTML when JavaScript inserts the schema after the initial response.
Schema Markup Checker Example
An Article JSON-LD block might parse with headline and author but still need image, datePublished, and publisher details for a specific search feature. The page content must support every claim.
Frequently Asked Questions About Schema Markup Checker
Is valid Schema.org markup guaranteed to produce a rich result?
No. Search engines decide eligibility using supported types, required properties, content policies, page quality, and other systems.
Can this checker see schema added by JavaScript?
It depends on what the server endpoint renders. If the markup exists only after client-side execution, compare the browser DOM and a search engine's rendered HTML.
Should I use JSON-LD, Microdata, or RDFa?
All can express Schema.org data, but JSON-LD is often easier to maintain separately from visible HTML. Use a format your publishing system can keep accurate.
