- Have imported Google Analytics 4 conversions for 15 days.
To switch your biddable conversions to Google Analytics 4, make the following updates to your action optimization settings (based on your current conversion actions):
- Apply the new conversion action optimization recommendations provided in Google Ads. Once you’ve done this, no further action is needed.
- Manually swap the action optimization settings on your current Universal Analytics and Google Analytics 4 actions.
Projected changes to historical data based on new action optimization settings
Before you save your new action optimization settings, you’ll be able to review the projected changes to your conversion metrics. Google Ads provides a “Conversions” percentage and a “Conversion value” percentage to help you understand the potential impact of your switch to Google Analytics 4. These numbers are based not only on your “primary” and “secondary” settings, but also on information collected from a 15-day tracking period.
