Occasionally, you may find that your Performance Max campaigns are not serving as many impressions as you would expect, or are not spending much of your set daily budget. In this article, we’ll outline common reasons why your ads may not be serving, and how you can troubleshoot using the tools in Google Ads.

What to expect when a campaign is enabled

- For campaigns using automated bidding strategies, it is recommended to wait 1-2 weeks to allow systems to ramp up and start performing towards your set goal.
- It may take Google Ads some time to adjust serving if you make changes to your campaign settings.
