Label assets that are AI edited or created

AI regulations in the European Union, India, and New York require that ads with certain AI-generated or edited assets include disclosures and/or labels that inform consumers that the ads were made with AI.

Add labels directly to your creatives or use the AI label setting in Google Ads, Display & Video 360, Campaign Manager 360, Merchant Center, and Ads Editor to add AI labels to your creatives. Learn more about how to Use AI content label settings to label your ads.

Why this issue is happening

When multiple offers with the same value for the VIN [vin] attribute for a country and language are uploaded in your product feed, a duplicate offer is created. A duplicate offer may cause serving issues and impression loss in your Merchant Center account. For example, if offers “us/en/123” and “us/en/124” use the same value for the VIN [vin] attribute, this will result in a duplicate offer.


How to fix your issue

To fix this issue, make sure that only one offer exists for each VIN [vin] attribute within a specific language and country by modifying or deleting the duplicate offers.

Creating multiple offers for the same car (using the same VIN) that serve in different local stores may also cause duplicate offers. If this happens, remove the duplicate offers and use the vehicle fulfillment [vehicle_fulfillment] attribute to enter multiple store codes for the same offer.

Fix multiple products at once

  1. Go to Products in Merchant Center, then select the Needs attention tab.
  2. Use the filter icon above the table to find all products affected by your issue.
  3. Select the download icon to download a list (.csv) of all affected products for all issues or this particular issue.
  4. Search your product data for those products (using the ID). Make sure that the offers are using different values for the VIN [vin] attribute. Remove any duplicate offers with the same values for the VIN [vin] attribute within a specific language and country.
    • Make sure each vehicle image is of high-quality without any overlays.
  5. Reupload your corrected product data to Merchant Center using your chosen upload method.
