## Example

Your video campaigns spent **\$8,500** and generated **425,000 ThruPlay views** this month:

| Channel     | Spend       | ThruPlay Views | Cost Per ThruPlay |
| ----------- | ----------- | -------------- | ----------------- |
| Meta Ads    | \$5,000     | 250,000        | \$0.020           |
| Google Ads  | \$2,000     | 100,000        | \$0.020           |
| TikTok Ads  | \$1,500     | 75,000         | \$0.020           |
| **Blended** | **\$8,500** | **425,000**    | **\$0.020**       |

## How It Works

Blended Cost Per ThruPlay divides your total ad spend by the number of ThruPlay views across all connected platforms. A ThruPlay counts when users watch to completion or for at least 15 seconds—measuring meaningful video engagement rather than passive impressions.
