## Example

Your campaigns spent **\$18,000** and generated **120,000** 30-second video views this month:

| Channel     | Spend        | 30s Views   | Cost/30s View |
| ----------- | ------------ | ----------- | ------------- |
| Meta Ads    | \$10,000     | 80,000      | \$0.125       |
| Google Ads  | \$5,000      | 25,000      | \$0.200       |
| TikTok Ads  | \$3,000      | 15,000      | \$0.200       |
| **Blended** | **\$18,000** | **120,000** | **\$0.150**   |

## How It Works

Blended Cost per 30-Second Video View aggregates your total ad spend and 30-second video views across all connected platforms, then calculates the average cost per engaged view. This metric focuses on viewers who watched at least 30 seconds, filtering out quick scrolls and providing a clearer picture of meaningful video engagement efficiency.
