# Avg. Interactions: Total Engagement Events

> Average count of all interaction events per session including clicks, keypresses, scrolls, and more.

<Tip>
  Avg. Interactions measures the average count of all interaction events (clicks, keypresses, scrolls, etc.) per session.
</Tip>

## Formula

<Info>
  **Avg. Interactions** = **Total Interaction Events** ÷ **Session Count**

### Formula Components

| Metric                                                                | Definition                                               |
| --------------------------------------------------------------------- | -------------------------------------------------------- |
| **Total Interaction Events**                                          | Sum of all clicks, keypresses, scrolls, and other events |
| [**Session Count**](/reference/metrics/funnel/sessions/session-count) | Total number of sessions                                 |

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

***

## Example

Sessions averaged **47 interactions** per visit across **10,000 sessions**.

| Device  | Sessions | Avg. Interactions |
| ------- | -------- | ----------------- |
| Desktop | 4,000    | 62                |
| Mobile  | 5,000    | 38                |
| Tablet  | 1,000    | 45                |

***

## How It Works

The Upstack Pixel tracks multiple interaction types: clicks, keypresses, scroll events, touch gestures, and more. This metric aggregates all interaction events to provide a complete picture of visitor activity.

## When to Use

| Scenario                     | Action                                         |
| ---------------------------- | ---------------------------------------------- |
| Comparing device experiences | Identify UX gaps across devices                |
| Content engagement analysis  | Measure interactive vs. passive content        |
| Session quality assessment   | Use alongside time metrics                     |
| Bot detection                | Unusual interaction patterns may indicate bots |
