Additional Features Explained

Click-Through Rate (CTR)

CTR measures the percentage of ad viewers who clicked the ad. It is calculated as:CTR=(Total ClicksTotal Impressions)×100CTR = \left(\frac{\text{Total Clicks}}{\text{Total Impressions}}\right) \times 100CTR=(Total ImpressionsTotal Clicks​)×100

Higher CTR indicates more engaging ads or better targeting.

Cost Per Click (CPC)

CPC tells you how much you paid on average for each click:CPC=Total CostTotal ClicksCPC = \frac{\text{Total Cost}}{\text{Total Clicks}}CPC=Total ClicksTotal Cost​

This metric is crucial for campaigns focused on driving traffic or conversions.
