# Avg. Max Scroll Depth: Page Consumption Depth

> Track how far visitors scroll on average per session. Higher scroll depth indicates visitors are consuming more content.

<Tip>
  Avg. Max Scroll Depth measures how far down the page visitors scroll on average per session, indicating content consumption depth.
</Tip>

## Formula

<Info>
  **Avg. Max Scroll Depth** = **SUM** ( Max Scroll Depth per Session ) ÷ **Session Count**
</Info>

### Formula Components

| --------------------------------------------------------------------- | ------------------------------------------------------ |
| **Max Scroll Depth per Session**                                      | Furthest scroll point reached in each session (0-100%) |
| [**Session Count**](/reference/metrics/funnel/sessions/session-count) | Total number of sessions                               |

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

## Example

Visitors scrolled to **72% of page content** on average across **8,000 sessions**.

| Page Type        | Sessions | Avg. Scroll Depth |
| ---------------- | -------- | ----------------- |
| Homepage         | 3,000    | 65%               |
| Product Pages    | 3,500    | 82%               |
| Blog Posts       | 1,000    | 78%               |
| Collection Pages | 500      | 58%               |

## How It Works

The Upstack Pixel tracks the maximum scroll position reached during each session. This is expressed as a percentage of the total page height. Pages with content below the fold are better measured by scroll depth than time on page.

## When to Use

| Scenario                       | Action                                   |
| ------------------------------ | ---------------------------------------- |
| Low scroll depth on long pages | Move important content higher            |
| Product page analysis          | Ensure key info is above fold            |
| Blog content optimization      | Measure how much content is consumed     |
| Landing page testing           | Compare scroll behavior between variants |
