Google Merchant Center requires the GTIN (The Global Trade Item Number) and asks to add your product’s globally valid GTIN for every product listed. We are using the Google Product Feed plugin for the WooCommerce, which has GTIN-related sections, but the WCVeendor plugin doesn’t have it from the Vendor Dashboard for vendors to enter their GTIN numbers for their products. The Google team insists that we enter the GTIN number for every product. Products that do not have GTIN show “Limited performance due to missing value [gtin],” which limits our visibility on paid search campaigns by Google. So it would be great if WCVendor Pugin had a box for the GTIN number so vendors could enter it when adding their products. Thank you.
