# Bounce Rate (No Interaction): Zero-Engagement Sessions

> Track sessions with zero meaningful interactions. A stricter bounce measure that identifies completely disengaged visitors.

<Tip>
  Bounce Rate (No Interaction) measures sessions where visitors left without any clicks, scrolls, or engagement events—a stricter disengagement signal than standard bounce rate.
</Tip>

## Formula

<Info>
  **Bounce Rate (No Interaction)** = ( **Zero-Interaction Sessions** ÷ **Total Sessions** ) × 100
</Info>

### Formula Components

| Metric                                                                 | Definition                                             |
| ---------------------------------------------------------------------- | ------------------------------------------------------ |
| **Zero-Interaction Sessions**                                          | Sessions with no clicks, scrolls, or engagement events |
| [**Total Sessions**](/reference/metrics/funnel/sessions/session-count) | Total number of visits to your website                 |

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

## Example

Your site had **10,000 sessions** with **1,500 zero-interaction bounces**, resulting in a **15% no-interaction bounce rate**.

| Traffic Source | Sessions | No-Interact Bounces | Rate |
| -------------- | -------- | ------------------- | ---- |
| Organic Search | 4,000    | 400                 | 10%  |
| Paid Social    | 3,000    | 600                 | 20%  |
| Direct         | 2,000    | 300                 | 15%  |
| Email          | 1,000    | 200                 | 20%  |

## How It Works

Unlike standard bounce rate, this metric only counts sessions where the visitor took absolutely no action—no scrolling, no mouse movement, no clicks. This indicates visitors who likely misclicked or found the page completely irrelevant.

## When to Use

| Scenario                    | Action                                             |
| --------------------------- | -------------------------------------------------- |
| High no-interaction bounces | Check for technical issues or mismatched targeting |
| Bot traffic detection       | Unusually high rates may indicate bot activity     |
| Ad fraud investigation      | Compare across traffic sources                     |
| Landing page optimization   | Identify pages that fail to capture any attention  |
