# Bounce Rate: Single-Page Session Percentage

> Track your e-commerce store's bounce rate to understand what percentage of sessions leave without engagement. Optimize landing pages and reduce exits.

<Tip>
  Bounce Rate measures the percentage of sessions where visitors left after viewing only one page without any further interaction.
</Tip>

## Formula

<Info>
  **Bounce Rate** = ( **Bounced Sessions** ÷ **Unique Sessions** ) × 100

### Formula Components

| Metric                                                                     | Definition                                                                               |
| -------------------------------------------------------------------------- | ---------------------------------------------------------------------------------------- |
| **Bounced Sessions**                                                       | Sessions where the visitor viewed only one page and left without additional interactions |
| [**Unique Sessions**](/reference/metrics/funnel/awareness/unique-sessions) | Total distinct sessions tracked by the Upstack pixel                                     |

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

## Example

Your online store recorded **15,000 unique sessions** this week with **4,500 bounced sessions**.

| Metric           | Value   | Calculation          |
| ---------------- | ------- | -------------------- |
| Unique Sessions  | 15,000  | Total site sessions  |
| Bounced Sessions | 4,500   | Single-page sessions |
| **Bounce Rate**  | **30%** | 4,500 ÷ 15,000 × 100 |

***

## How It Works

The Upstack pixel tracks each session and monitors whether visitors navigate to additional pages or trigger engagement events. A session counts as "bounced" if the visitor leaves after only the landing page view. Lower bounce rates indicate better engagement and content relevance.

## When to Use

| Scenario                     | Action                                                         |
| ---------------------------- | -------------------------------------------------------------- |
| High bounce on landing pages | Improve page load speed, content relevance, or calls-to-action |
| Comparing traffic sources    | Identify channels sending low-intent traffic                   |
| Evaluating page redesigns    | Monitor before/after bounce rates to measure impact            |
| Diagnosing funnel drop-off   | High bounce indicates awareness-to-engagement gap              |
