## Example

Your brand spent **\$8,400** across all platforms in March and received **12,000 clicks**:

| Platform    | Spend       | Clicks     | CPC        |
| ----------- | ----------- | ---------- | ---------- |
| Meta Ads    | \$4,200     | 7,000      | \$0.60     |
| Google Ads  | \$2,800     | 3,500      | \$0.80     |
| TikTok Ads  | \$1,400     | 1,500      | \$0.93     |
| **Blended** | **\$8,400** | **12,000** | **\$0.70** |

## How It Works
