# Avg. Funnel Stage: Purchase Funnel Progress

> Average deepest funnel stage reached per session, from landing (0) to purchase (6). Higher means more visitors reach checkout.

## Example

Sessions averaged a funnel stage of **2.4/6**, indicating most visitors view products but few reach checkout.

| Funnel Stage | Description      | Sessions | % of Total |
| ------------ | ---------------- | -------- | ---------- |
| 0            | Landing          | 10,000   | 100%       |
| 1            | Browse           | 7,500    | 75%        |
| 2            | Product View     | 5,000    | 50%        |
| 3            | Add to Cart      | 2,000    | 20%        |
| 4            | Begin Checkout   | 800      | 8%         |
| 5            | Shipping/Payment | 500      | 5%         |
| 6            | Purchase         | 300      | 3%         |

## How It Works

The purchase funnel is divided into stages: Landing (0), Browse (1), Product View (2), Add to Cart (3), Begin Checkout (4), Shipping/Payment (5), and Purchase (6). This metric averages the maximum stage reached across all sessions.
