Campaign Budget Optimization
A setting that distributes one campaign budget across ad sets automatically, shifting spend toward the best performing groups.
What it means in practice
The advertiser sets a campaign-level budget while Meta allocates spend among eligible ad sets based on predicted opportunities. Ad set spending controls may guide allocation when specific audience groups require minimum or maximum investment.
Why it matters
Automated allocation can concentrate spend before every audience or creator concept receives equal testing exposure.
How it is used
A brand places several audience-focused ad sets under one budget and lets Meta direct spend toward the UGC combinations producing results.
