Please help me to solve this error that the Google application is generating in my products
my products do not contain barcodes
Topic summary
Issue: Products are receiving a “Demoted: Limited performance due to missing value [gtin]” error in Google Shopping Ads, indicating they lack Global Trade Item Numbers (GTINs) - unique product identifiers required by Google.
Proposed Solutions:
- Add GTINs to products if available
- Use alternative identifiers like Manufacturer Part Number (MPN) or Brand if GTINs don’t exist
- Set the ‘identifier exists’ attribute to ‘false’ in the product data feed if products genuinely lack these identifiers
- Request an exemption from Google Merchant Center for products without standard identifiers
- Access Google Merchant Center > Products > Feeds to apply feed rules and correct the data
Current Status: The original poster attempted the suggested fixes but reports the error persists. A video tutorial was shared to guide the resolution process. Another user has encountered the same issue, suggesting this is a common problem for Shopify merchants using Google Shopping integration.

Hello @FelipeSubli ,
Good day! Gina from flareAI app helping Shopify merchants get $6Million+ in sales from Google Search, on autopilot.
If you are receiving the error “Demoted limited performance due to missing value [gtin] in shopping_ads” for your products in Google Shopping Ads, it means that your products are missing the Global Trade Item Number (GTIN), which is a unique identifier used to identify products globally.
To resolve this issue, you should try to obtain the GTIN for your products and add them to your product feed. If your products do not have a GTIN, you can try to provide other unique product identifiers such as Manufacturer Part Number (MPN) or Brand, as per the requirements of Google Merchant Center.
If you are unable to obtain a GTIN or any other unique product identifier, you may be able to request an exemption from Google Merchant Center by submitting a request form with detailed information about your products. Or you can submit the products to Google without GTIN attribute. To do this, you need to set the ‘identifier exists’ attribute to ‘false’ in your product data feed. This tells Google that your products do not have GTINs.
Once you have added the necessary product identifiers, ensure that your product feed is updated, and then request a review of your products in Google Merchant Center to remove the error and improve the performance of your Shopping Ads.
Keep in mind that not having GTINs may impact the performance of your Shopping ads, as Google uses this attribute to identify and categorize products. However, taking the steps above can help you avoid the “Demoted limited performance due to missing value [gtin] in shopping_ads” error and ensure that your products are still visible to potential customers.

The correct values you should see when you go to Google Merchant Center > products > all products > click on a product > scroll to the bottom and view the final attributes is there are no brand or mpn values.
And that the identifier exist attribute is set to no.
If you see other data then above, then by following the below video, will allow you to correct the issues.

However double check the products have no barcodes.
I still can’t solve it
The video I shared should allow you to fix it, I personally help someone every week, without any issues.
To do this, you need to set the ‘identifier exists’ attribute to ‘false’ in your product data feed.Can you please explain “Product feed data”? Thanks
@LaurieRubell Go to Google Merchant Center > Products > Feeds > the feed listed is your product feed data.
You can then click on the feed and then choose feed rules, and apply the rules.
I still can’t fix it, shopify keeps giving me the same error
