Campaign budget optimization (CBO) is a way of optimizing the distribution of a campaign budget across your campaign's ad sets. This means we automatically and continuously find the best active opportunities for results across your ad sets and distribute your campaign budget in real time to get those results.
A campaign budget is a budget you set at the campaign level (rather than the ad set level). The amount you set can apply to each day the campaign runs (daily budget) or over the lifetime of the campaign (lifetime budget). All campaign budgets use campaign budget optimization.
We optimize your campaign budget in real time on an opportunity-by-opportunity basis. Our goal is to get you the most results possible, and for the cost of those results to align with your bid strategy.
