| Channel      | Registrations | % of Total |
| ------------ | ------------- | ---------- |
| Paid Search  | 523           | 41.9%      |
| Social Media | 412           | 33.0%      |
| Email        | 198           | 15.9%      |
| Direct       | 114           | 9.2%       |

## How It Works

Complete Registration events are captured when a visitor submits a registration form on your site. The Upstack pixel tracks these submissions and associates them with the visitor's session and attribution data. This allows you to measure which channels and campaigns drive the most signups.
