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

Flexible daily budgeting allows for daily spend to fluctuate. On some days, the campaign might spend more than the $100 budget if Pinterest's algorithm identifies strong opportunities for conversions or clicks. On other days, it might spend less if opportunities are limited. However, over the course of a billing cycle (typically a month), the total spend will average out to the daily budget multiplied by the number of days in the cycle. This ensures that while daily spend isn't fixed, the overall budget is respected. It will not always be exactly $100, nor will it never exceed $100 on any given day. It also won't consistently reach $200 or more, as the system aims to average out to the set daily budget.
