## Example

Your site tracked **2,156 leads** across attribution channels in January.

| Channel    | Leads     | % of Total |
| ---------- | --------- | ---------- |
| Meta Ads   | 1,034     | 48.0%      |
| Google Ads | 583       | 27.0%      |
| Organic    | 345       | 16.0%      |
| Direct     | 194       | 9.0%       |
| **Total**  | **2,156** | **100%**   |

## How It Works

Leads counts every lead event tracked by the Upstack Pixel. When a visitor completes a lead action on your site—such as submitting a contact form, signing up for a newsletter, or requesting a quote—the pixel fires a lead event. This metric represents your total lead volume as captured by the tracking pixel, enabling accurate attribution analysis for lead generation campaigns.
