Structured Data 18 May 2026

When Your Schema Is Valid But Your Data Isn't

Product schema suppression, disappearing rich results, and Merchant Center disapprovals are almost always a data problem. Five failure patterns, a 3-layer alignment model, and an operational audit checklist.

Available now 02 · Chrome extension

Schema Extractor.

JSON-LD, Microdata, RDFa — one click on the toolbar.

Extracts all structured data from any page — JSON-LD, Microdata, and RDFa — and shows it in a clean tabbed viewer. The toolbar badge tells you what's on a page before you click. No DevTools. No view-source.

Rich results don't happen by accident. For SEOs who know valid ≠ correct.
