Campaign Budget Optimization
A Meta campaign setting where budget is managed at the campaign level by the algorithm.
Why It Matters
CBO uses Meta's algorithm to automatically distribute budget to your best-performing ad sets. Instead of manually moving budget around, you set campaign-level budgets and let Meta optimize. For most advertisers, CBO outperforms manual allocation because it can react faster than humans.
Practical Example
Scenario
A brand with 5 ad sets switches from ABO ($100/ad set = $500 total) to CBO ($500 at campaign level). Day 1: one ad set gets $250, others get $50-75 based on performance.
Result
CBO automatically scales the winner while testing others. Weekly ROAS improves 15% as budget flows to what works.
Pro Tips
- 1Use CBO when you trust the algorithm—give it enough budget and conversion volume to learn
- 2Set ad set minimum/maximum spend limits if you want to ensure budget diversity
- 3CBO works best with similar audience sizes across ad sets—one huge audience will dominate
