Within the Instagram Ads Manager, what is the primary purpose of the 'Campaign Budget Optimization' (CBO) feature?

The primary purpose of the 'Campaign Budget Optimization' (CBO) feature within Instagram Ads Manager is to automatically distribute the campaign budget across the ad sets within that campaign to get the best overall results. Instead of manually setting a budget for each individual ad set, CBO allows the Facebook algorithm to dynamically allocate the budget to the ad sets that are performing the best in real-time. This means that ad sets with lower costs per result (e.g., cost per click, cost per conversion) will receive a larger portion of the budget, while underperforming ad sets will receive less. For example, if you have a campaign targeting two different age groups with separate ad sets, and the algorithm determines that one age group is more responsive to your ads, CBO will automatically shift more of the campaign budget to that ad set. CBO is designed to maximize the efficiency of your ad spend and improve overall campaign performance by optimizing budget allocation.
