## Example

Your campaigns generated **1,247 completed registrations** across all channels last month:

| Channel     | Registrations | Share    |
| ----------- | ------------- | -------- |
| Meta Ads    | 623           | 50%      |
| Google Ads  | 412           | 33%      |
| TikTok Ads  | 212           | 17%      |
| **Blended** | **1,247**     | **100%** |

## How It Works

Blended Completed Registrations aggregates registration completion events reported by each connected advertising platform. When a user completes an account registration that's attributed to an ad, each platform reports it as a completed registration. This metric sums those registrations across Meta, Google, and TikTok to give you a unified view of account signup performance.
