## Example

Your store spent **\$15,000** on advertising last month and generated **\$52,500** in attributed revenue:

| Platform    | Spend        | Revenue      | Platform ROAS |
| ----------- | ------------ | ------------ | ------------- |
| Meta Ads    | \$8,000      | \$28,000     | 3.5x          |
| Google Ads  | \$5,000      | \$17,500     | 3.5x          |
| TikTok Ads  | \$2,000      | \$7,000      | 3.5x          |
| **Blended** | **\$15,000** | **\$52,500** | **3.5x**      |

## How It Works

Blended ROAS aggregates spend and attributed purchase revenue across all connected ad platforms. A ROAS of 3x means you generate \$3 in revenue for every \$1 spent on ads. This provides a unified view of advertising efficiency without manually combining platform data.

| -------------------------------- | --------------------------------------------------------- |
| Evaluating overall ad efficiency | Compare Blended ROAS to your target (e.g., 3x minimum)    |
| Reporting to stakeholders        | Use as the single efficiency metric across all paid media |
| Budget allocation decisions      | Compare to platform-specific ROAS to identify winners     |
| Profitability analysis           | Combine with margin data to assess true ad profitability  |
