## Example

Your site recorded **2,340 sign ups** this month from paid campaigns:

| Channel    | Sign Ups | Share |
| ---------- | -------- | ----- |
| Meta Ads   | 1,287    | 55%   |
| Google Ads | 702      | 30%   |
| TikTok Ads | 351      | 15%   |

## How It Works

Upstack counts sign up events fired by your pixel when visitors complete account registration. Each unique sign up event increments the count, providing visibility into how effectively your campaigns drive account creation.
