Analysis results
Preparing the local analyzer.
Download the derived report with its measurement details. It does not include the original input file.
Prepare your evidence
Copy the JSON content of your page's application/ld+json script, without its HTML tags. Supply a JSON object or array. Review missing local references and malformed value structures. Repeated identifiers can be valid merged definitions. Remote contexts and search-engine eligibility are not evaluated; retest the actual page after making a change.
Read the result and check the repair
Start with the observed failures and their evidence. Follow the next action for the affected item, then collect a new report using the same scope. Use the earlier report when this tool supports comparison. Differences between sites, collection windows or test conditions can prevent a meaningful comparison.
Local processing and limits
Files and pasted evidence are analyzed in your browser. They are not uploaded, added to the page address or saved in browser storage. Each input is limited to 2 MiB, with further limits shown by the analyzer. Closing or clearing this page removes its report from the page.
Exports contain the derived findings and measurement details. Review names, paths and text before sharing. A successful check describes the supplied evidence; it does not certify a whole website or replace a staging test.
