What the app checks
Product completeness
Titles, vendor/brand presence, Online Store URLs and product images.
Image readiness
Observable image dimensions are checked against the 500×500 readiness target used in current Merchant Center preparation.
Variant identifiers
Flags variants with neither SKU/MPN nor barcode/GTIN, without inventing identifiers.
Price and variant structure
Flags non-positive prices and duplicate option combinations that can create feed or catalog ambiguity.
Current scan boundaries
- Up to 2,500 products per scan.
- Up to 100 variants per product.
- Up to 20 images per product.
- The app warns when a scan boundary is reached.
This is a catalog-readiness check, not a guarantee of approval by Google Merchant Center or any other sales channel. The app does not connect to a merchant's Google Merchant Center account.
