- Enables retargeting

Campaign Optimization
Testing Strategy
What to test:

- Placements
- Ad formats
- Landing pages
Testing best practices:
- Test one variable at a time
- Run tests for at least 7 days
- Minimum 50 conversions for significance
- Document learnings
- Implement winners, kill losers
Campaign Budget Optimization (CBO)
How it works:
- Budget set at campaign level
- Facebook distributes to best-performing ad sets
- Algorithmic optimization
When to use:
- Multiple ad sets
- Want automated optimization
- Similar ad sets competing
Best practices:
- Minimum 2, maximum 6 ad sets
- Don’t mix very different audiences
- Allow learning phase to complete
- Set minimum spend per ad set if needed
The Learning Phase
What it is:
- Algorithm learning which users to show ads to
- Occurs when creating new campaigns or making significant edits
- Performance typically unstable
During learning:
- Avoid major edits
- Let run for 50 optimization events
- Performance may be worse initially
- Don’t panic and stop early
Exiting learning:
- Complete naturally (50 events)
- Or accelerate by increasing budget
When to Scale
Scale when:
- Campaign is profitable
- Consistent performance for 7+ days
- Learning phase complete
- Budget allows
How to scale:
- Increase budget 20% every 3-4 days
- Duplicate winning ad sets
- Expand to similar audiences
