Limited Performance Due to Missing Identifiers (GTIN, MPN, brand)
This error happens when one or more values that you submitted for a unique product identifier (UPI) are either missing or invalid. Products affected by this error are still eligible to show up in Google Shopping Ads; however, their performance is poor (Lower ad rank).
Among the three identifiers, you can provide at least 2 for Google to approve your products. Since some products do not have a GTIN assigned, you can submit the MPN and brand instead when using Google Shopping Feed by Omega
- To add the MPN field, check with your supplier to get the correct MPN for your products. Then, go to Shopify > Products > Edit your variant > Add the MPN into the SKU box.
Now add the MPN to the SKU box
- To add the brand, please contact us for support submitting your brand
Google will verify all the GTINs that you submitted and will notify you if those are incorrect. There are 2 different causes and corresponding solutions to this error:
- You provided the incorrect GTIN. The GTINs are different based on the product type and the target country, therefore, make sure your GTINs are correct.
