## Example

Your B2B company spent **\$8,500** promoting lead magnets in March, generating **1,700 downloads**.

| Content Campaign    | Spend       | Downloads   | Cost/Download |
| ------------------- | ----------- | ----------- | ------------- |
| Industry Report Ads | \$4,000     | 920         | \$4.35        |
| Ebook Promotion     | \$2,500     | 480         | \$5.21        |
| Guide Retargeting   | \$2,000     | 300         | \$6.67        |
| **Total**           | **\$8,500** | **\$1,700** | **\$5.00**    |

## How It Works

The metric divides total advertising spend by the number of content download events tracked by the Upstack Pixel. Lower costs indicate more efficient content distribution. This helps identify which content assets and promotion channels deliver the best engagement value.
