ABO

Ad Set Budget Optimization — budgets set at the ad-set level instead of the campaign. Gives manual control over which audiences get spend; best for testing.

ABO (Ad Set Budget Optimization) is a Meta campaign structure where you set budgets at the ad-set level rather than the campaign level. Each ad set has its own daily budget and spends independently of others in the same campaign.

When to use ABO:

ABO is usually the right starting structure while you're learning what works. Once you have 3-5 proven winners, operators often graduate to CBO to let Meta allocate between them.
