# Cost per View Category: Collection Page Traffic Efficiency

> Track cost per view category event to measure collection page traffic efficiency. Calculate ad spend per category page visit tracked by the Upstack pixel.

<Tip>
  The average ad spend required to drive one view category event (collection page visit) tracked by the Upstack pixel.
</Tip>

## Formula

<Info>
  **Cost per View Category** = **Channel Spend** ÷ **View Category Events**
</Info>

### Formula Components

| Metric                   | Definition                                                            |
| ------------------------ | --------------------------------------------------------------------- |
| **Channel Spend**        | Total advertising spend across the selected channel or all channels   |
| **View Category Events** | Number of collection/category page views tracked by the Upstack pixel |

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

## Example

Your campaigns spent **\$5,000** and drove **25,000 view category events** this month:

| Channel    | Spend       | View Category Events | Cost per View Category |
| ---------- | ----------- | -------------------- | ---------------------- |
| Meta Ads   | \$3,000     | 18,000               | \$0.17                 |
| Google Ads | \$2,000     | 7,000                | \$0.29                 |
| **Total**  | **\$5,000** | **25,000**           | **\$0.20**             |

## How It Works

Cost per View Category calculates the average cost to drive a visitor to a collection or category page on your site. The Upstack pixel fires a View Category event each time a visitor lands on a collection page, giving you precise cost efficiency data independent of ad platform reporting.
