| Google Ads | $5,000 | 1,000,000 | $5.00 |
| TikTok Ads | $2,000 | 400,000 | $5.00 |
| Blended | $15,000 | 3,000,000 | $5.00 |
How It Works
Blended CPM aggregates your total ad spend and impressions across all connected advertising platforms, then calculates the cost per 1,000 impressions. This gives you a single efficiency metric for your entire paid media program regardless of channel mix.
