Campaign Budget Optimization
Also: CBO; Advantage+ campaign budget
Setting the budget at the campaign level and letting the platform distribute it across ad sets by performance, rather than fixing a budget per ad set. CBO favors ad sets that convert cheaply, which can starve prospecting in favor of retargeting unless minimums are set.
