# Avg. Sessions per Visitor: Measure Return Visit Frequency

## Formula

<Info>
  **Avg. Sessions per Visitor** = **Sessions** ÷ **Unique Visitors**

### Formula Components

| -------------------------------------------------------------------------- | ----------------------------------------------------------- |
| [**Sessions**](/reference/metrics/funnel/awareness/unique-sessions)        | Count of distinct sessions tracked by the Upstack pixel     |
| [**Unique Visitors**](/reference/metrics/funnel/awareness/unique-visitors) | Distinct individuals identified across devices and sessions |

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

## Example

Your store had **8,400 unique visitors** who generated **12,600 sessions** in March:

| Week      | Visitors  | Sessions   | Avg. Sessions/Visitor |
| --------- | --------- | ---------- | --------------------- |
| Week 1    | 2,100     | 2,940      | 1.40                  |
| Week 2    | 2,000     | 3,000      | 1.50                  |
| Week 3    | 2,200     | 3,300      | 1.50                  |
| Week 4    | 2,100     | 3,360      | 1.60                  |
| **Total** | **8,400** | **12,600** | **1.50**              |

## How It Works

Avg. Sessions per Visitor divides the total number of sessions by unique visitors identified through the Upstack pixel's identity resolution. A value of 1.0 means each visitor came once; higher values indicate visitors return multiple times before converting. Rising values suggest growing brand affinity.
