Fill in the blank: If the projected spend of all line items sums to an amount less than your order budget, then your budget is _______

The correct answer is Underpacing because if the projected spend of all line items sums to an amount less than the order budget, it means that the campaign is not spending as expected and is behind the pace required to fully utilize the budget. Underpacing indicates that the campaign is not using the allocated budget efficiently, which could result in missed opportunities to reach the target audience or deliver the desired results within the set time frame. This situation often requires optimization adjustments, such as increasing bids or broadening targeting, to ensure the campaign spends its full budget and meets its performance goals.
