# Turning on Campaign Budget Optimization

If your campaign includes multiple ad sets, the platform can dynamically optimize budgets between them using the **Campaign Budget Optimization** feature. The process varies between new and existing campaigns.

## **New Campaign**

1. Create a new campaign on the **Campaigns** screen by clicking **Add Campaign**.
