Overview
You can change Ad Set daily budgets even when Cruise Control is active. Cruise Control adjusts Campaign-level budgets; Ad Set budgets operate independently.
How Cruise Control Works
Cruise Control automatically adjusts Campaign-level daily budgets to keep spending on pace with your budget target. It:
- Operates at the Campaign level only
- Adjusts Campaign daily budgets based on pacing recommendations
- Does not modify Ad Set budgets
Ad Set Budget Changes
You can change Ad Set daily budgets at any time, including when Cruise Control is active. These changes:
- Work independently of Cruise Control
- Are not blocked or prevented by Cruise Control
- Are applied directly to the Ad Set in Meta
Important Considerations
Independent Operation
- Cruise Control adjusts Campaign budgets
- Ad Set budgets are separate in Meta’s budget structure
- Changes at each level operate independently
No Automatic Coordination
The platform does not automatically coordinate between:
- Cruise Control Campaign budget adjustments
- Manual Ad Set budget changes
Best Practices
1. Understand Meta’s budget hierarchy:
- Campaign-level budgets control overall Campaign spending
- Ad Set budgets control spending for individual Ad Sets
- Both can be active simultaneously
2. Monitor both levels:
- Check Campaign budgets adjusted by Cruise Control
- Review Ad Set budgets you’ve set manually
- Ensure total spending aligns with your goals
3. When using Cruise Control:
- Set Campaign-level Cruise Control settings (Min, Max, Default)
- Be aware that Cruise Control only affects Campaign budgets
- Manually manage Ad Set budgets if needed
How to Change Ad Set Budgets
Ad Set budgets can be changed through:
- The Shape API (if you have API access)
- Direct updates via the Ad Set update endpoints
Note: The Ad Set settings form in the UI currently supports status changes only. Budget changes are available via API.
