## Example

Your campaigns delivered **2.4M impressions** across all channels last week:

| Platform   | Impressions | Share |
| ---------- | ----------- | ----- |
| Meta Ads   | 1,200,000   | 50%   |
| Google Ads | 840,000     | 35%   |
| TikTok Ads | 360,000     | 15%   |

## How It Works

Blended Impressions aggregates impression counts from each connected advertising platform into a single metric. Each platform reports impressions differently—Meta counts each ad view, Google counts each ad load, and TikTok counts viewable impressions. This metric sums them all for a unified view of total ad delivery.
