| Channel     | Spend        | Reach       | CPP         |
| ----------- | ------------ | ----------- | ----------- |
| Meta Ads    | \$6,000      | 250,000     | \$0.024     |

| TikTok Ads  | \$2,000      | 50,000      | \$0.040     |
| **Blended** | **\$12,000** | **400,000** | **\$0.030** |

## How It Works

Blended CPP aggregates spend and reach data from all connected advertising platforms. It divides total spend by total unique people reached to show your average cost to reach one person. This metric helps evaluate cross-channel audience efficiency.
