Two products sharing a SKU confuse stock and orders.
WooCommerce does not stop you from saving the same SKU on two products. Inventory, support, and Shopping feeds then point at the wrong row. That is a money leak, not a health score.
Free Catalog Audit Pro lists duplicates — $49/year
Free on WordPress.org finds missing images, SKUs, and prices. Duplicate SKU is Pro, on the shop zip from shopgaps.com. Scans stay on your WordPress site.
What to do
- Install ShopGaps Catalog Audit and open WooCommerce → Catalog Audit.
- On Pro, open the duplicate SKU list. Make each SKU unique. Do not silently overwrite a SKU that already sells.
- If you want a ranked Monday list (duplicates plus Shopping data and variations), that is the Store Audit at USD $149.
