What are impressions, and how are they billed?
You use impressions when displaying your ads on any ad platform or website. Based on your current ad distribution, you can estimate how many you’ll need to use monthly and select that when you customize your plan at checkout.
How do I change or cancel the ad delivery and optimization enhancements?
If you want to change or cancel the number of impressions included in your plan, you can access the Subscriptions tab in Team Settings.
