To troubleshoot the issue of a display ad group not serving due to incorrect Target and bid settings, you should check your bid settings, review your targeting options, and monitor performance to make adjustments.
Step-by-step explanation:
If one of your display ad groups isn't serving due to incorrect Target and bid settings, there are several steps you can take to troubleshoot the issue:
1. Check your bid settings:
Make sure your bids are competitive enough to trigger your ads. You may need to increase your bids to increase the chances of your ads being shown.
2. Review your targeting options:
Ensure that your targeting options, such as keywords, placements, or audience demographics, are relevant to your ad group. If they are too restrictive, it may limit the reach of your ads.
