Fix guide

Insufficient product identifiers on Shopify

Google can’t uniquely match your SKU in its product graph. You keep the listing, but you lose comparison-shopping style visibility — often a 40–60% traffic haircut versus identified products.

Fix order

1. Add GTIN + brand when the product is mass-produced.
2. Else add brand + MPN.
3. Else set identifier_exists=false for unique/handmade goods.
4. Never submit fake GTINs — that creates conflicting identifier errors.
