The traditional method where advertisers manually allocate budgets to each ad set.

Why It Matters

ABO gives you direct control over how budget is allocated across ad sets. It's essential for structured testing where you need equal spend across audiences, or when you're scaling a proven ad set and don't want budget siphoned to others.

Practical Example

Scenario

A brand wants to test 4 new lookalike audiences equally before picking a winner. They use ABO with $500/day per ad set.

Result

Each audience gets exactly $500/day, allowing apples-to-apples comparison. After 7 days, they can confidently identify which audience to scale.

Pro Tips

  • 1Use ABO for testing phases where you need equal spend distribution
  • 2ABO is better for scaling proven winners—you control exactly how much goes where
  • 3Switch to CBO after identifying winners to let the algorithm optimize ongoing performance

Common Mistakes to Avoid

Using ABO for ongoing campaigns when CBO would optimize better than manual reallocation
Not checking ABO campaigns frequently enough—manual management requires manual monitoring
