An advertiser inputs a daily campaign budget of $100 and uses the average daily budgets feature. What will happen to the daily spend?

The average daily budgets feature on Pinterest, like similar features on other ad platforms, allows for flexibility in daily spend to optimize for performance. While the target is $100 per day, the system may spend more on days when it identifies higher potential for conversions or engagements, and less on days with lower potential. Over the course of a billing cycle (typically 30 days), the total spend will average out to the daily budget multiplied by the number of days in the cycle. Therefore, it won't always be exactly $100, nor will it never exceed $100. It's designed to optimize within a flexible daily range, not to fluctuate wildly to $200 or more, which would defeat the purpose of an average daily budget.
