Social Media Marketing (SMM), ABO and CBO are two different ways to manage your advertising budget, especially in platforms like Meta Platforms Ads.
1. ABO (Ad Set Budget Optimization)
With ABO, you set a separate budget for each ad set.
Example:
- Ad Set 1 (Age 18–24): ₹500/day
- Ad Set 2 (Age 25–34): ₹500/day
- Ad Set 3 (Age 35–44): ₹500/day
Each ad set spends only the budget you assign to it.
Advantages:
- Full control over each audience’s budget.
- Best for testing different audiences, interests, or creatives.
- Easy to compare ad set performance.
Disadvantages:
- You need to manually adjust budgets.
- High-performing ad sets cannot automatically use unused budget from weaker ones.
2. CBO (Campaign Budget Optimization)
With CBO, you set one budget at the campaign level, and the platform automatically distributes it among the ad sets based on performance.
Example:
- Campaign Budget: ₹1,500/day
- 3 Ad Sets
The system may spend:
- Ad Set 1: ₹900
- Ad Set 2: ₹450
- Ad Set 3: ₹150
It automatically gives more budget to the best-performing ad sets.
Advantages:
- Automatic budget optimization.
- Better for scaling campaigns.
- Saves time and can improve overall performance.
Disadvantages:
- Less control over individual ad set spending.
- Some ad sets may receive very little budget.
