# Performance boost projections

**Performance boost projections** help you understand the impact of pausing a losing ad. For every test result, Adalysis calculates the potential change if the losing ad is paused or deleted.

The performance change is calculated for five metrics: clicks, conversions, cost, CPA, and total conversion value. The boost projection is shown in two places under **Ad testing**:

### **For each test result**

To see individual test results, click on any ad group name in the ad testing section.

### **Aggregate account or campaign data**

Adalysis also aggregates performance boost data at the account or campaign level for single ad group tests.
