Google Merchant limited performance due to missing identifiers

4 0 2


I am getting the message that my ads are limited because I am missing identifiers mpn, brand, or gtin. I spoke with Google who told me that I need to set my identifier exists to false/no via my API, but am unsure where that identifier lives to update it. It is not in the bulk updater for Google fields on Shopify or anywhere else I can find on my Shopify Admin. 

Can someone point me to where that field lives? My ads have tanked because of this and I need to get this fixed ASAP?

When submitting product identifiers the following rule applies.

If a manufacturer has assigned a bar code, then submit brand, mpn (if available), GTIN and set identifier exists to yes.

If the manufacturer has not assigned a bar code, then remove the values brand, mpn, gtin and set identifier exists to no.


The easiest way is to use Feed Rules in Google Merchant Center, to learn more:

Hi, You can use other apps which can help you set your identifiers correctly. You can also bulk update these fields. 

AdNabu's Google Shopping Feed app automatically maps GTIN from Shopify to Google Merchant Center. AdNabu uses Barcode in Shopify as GTIN in Google Shopping. If your barcode is not properly formatted or is longer/shorter than Google's requirements, You will see an error in Google Merchant Center.

You can also check the Easy Google Shopping Feed app by AdNAbu, which manages your merchant center feed and other advanced features such as Multilanguage, Multicurrency, and Metafields. 

You can also get in touch with our experts and request a demo. 

Hope this helps.
