You may have multiple Shopping campaigns or ad groups in your account that are eligible to enter overlapping auctions due to similar targeting. Depending on preferences determining which one of your ads ultimately enters a given auction (for example, location, priority, and products), traffic might shift from one campaign to another that has similar targeting.
What you can do
- Checking product targeting overlaps between campaigns from the same Google Ads account:
Note: The instructions below are part of the new design for the Google Ads user experience. To use the previous design, click the "Appearance" icon, and select Use previous design. If you're using the previous version of Google Ads, review the Quick reference map or use the Search bar in the top navigation panel of Google Ads to find the page you’re searching for.
-
In your Google Ads account, click Assets.
-
Click Products.
-
Click "Diagnostics" tab.
- Click into products in the “Ready to Serve” status to help understand if there are product targeting overlaps.
- Checking product targeting overlaps between campaigns from different Google Ads accounts:
- Review if there are other Google Ads accounts linked to this Merchant Center account.
- If yes, check the Shopping campaigns set up in the other Google Ads accounts to see if the same product is being promoted.
- If you’d like to have multiple Shopping campaigns, you need to ensure that the campaigns are running at different times using ad scheduling or targeting different products or targeting different locations or running on different campaign priorities or linked to different Merchant Center accounts.
Note: To ensure optimal performance, it's recommended not to target a single product by more than a few dozen ad groups or campaigns.
