Blended ROAS measures how many dollars of purchase revenue you generate for every dollar spent on ads across all channels.
Blended ROAS = Blended Purchases Value ÷ Blended Spend
| Metric | Definition |

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.
