| Metric                                                              | Definition                             |
| ------------------------------------------------------------------- | -------------------------------------- |
| [**Page Views**](/reference/metrics/funnel/awareness/page-views)    | Total pages loaded across all sessions |
| [**Sessions**](/reference/metrics/funnel/awareness/unique-sessions) | Unique visitor sessions on your site   |

| Metadata        |                         |
| --------------- | ----------------------- |
| **Type**        | Number                  |
| **Data Source** | [Upstack Pixel](/pixel) |
| **Aggregation** | Average                 |

## Example

Your site recorded **4.2 pages per session** this month across 12,400 sessions:

| Traffic Source | Avg Pages/Session | Sessions |
| -------------- | ----------------- | -------- |
| Organic Search | 5.1               | 4,200    |
| Email Campaign | 4.8               | 2,800    |
| Paid Social    | 3.2               | 3,100    |
| Direct         | 3.9               | 2,300    |

## How It Works

Each time a visitor lands on your site, Upstack starts a session. Every page they view increments the page view count. Dividing total page views by total sessions gives you the average browsing depth across all visitors.

| ------------------------------- | ----------------------------------------------------- |
| Measuring content engagement    | Higher values indicate visitors explore more pages    |
| Evaluating landing page quality | Low values suggest visitors leave without exploring   |
| Comparing traffic sources       | Identify which channels bring more engaged visitors   |
