A natural health advertiser experiences supply chain issues and online product delays, but it wants to capitalize its daily spend when there is an opportunity. However, the advertiser also wants the ability to turn the continuous campaign off if a product shortage occurs. Which budgeting option should this advertiser use?

Flexible daily budgeting is the best option because it allows the advertiser to set a daily budget that Pinterest can exceed by up to 20% on days with high-opportunity traffic, while still adhering to the overall campaign budget over the billing period. This addresses the need to capitalize on opportunities. Crucially, it also provides the ability to pause or turn off the campaign instantly if supply chain issues worsen, offering the desired control. Lifetime budgeting allocates a total budget over the campaign's duration, but doesn't offer the same flexibility for daily fluctuations or immediate pausing without manual adjustments. Average daily and fixed daily budgets are too rigid; they don't allow for daily spend increases on high-opportunity days.
