What is ABO? Ad set budget optimization explained

ABO (ad set budget optimization) sets a separate budget on each ad set instead of one shared campaign budget.

Example

A test with three ad sets at $50/day each spends $50 on each regardless of early results.

Why does ABO matter for e-commerce?

ABO guarantees each test cell gets spend, which makes creative and audience tests easier to read.
