# Blended View-Through Conversions: Ad View Attribution

> Track conversions from users who saw but didn't click your ads across Meta, Google, and TikTok. Measure view-through attribution impact.

<Tip>
  Blended View-Through Conversions counts users who saw your ad, did not click, but converted later—aggregated across all connected ad platforms.
</Tip>

## Formula

## Example

Your campaigns generated **847 view-through conversions** last month across all platforms.

| Platform | Impressions | VT Conversions | VT Rate |
| -------- | ----------- | -------------- | ------- |
| Meta     | 125,000     | 412            | 0.33%   |
| Google   | 98,000      | 287            | 0.29%   |
| TikTok   | 67,000      | 148            | 0.22%   |

## How It Works

Each ad platform tracks when users view your ads without clicking. If those users later convert within the platform's attribution window, the conversion is credited as view-through. Upstack aggregates these counts across Meta, Google, and TikTok for a unified view.

## When to Use

| Scenario                           | Action                                           |
| ---------------------------------- | ------------------------------------------------ |
| Measuring brand awareness impact   | Compare VT vs click-through conversion ratios    |
| Evaluating display/video campaigns | VT conversions indicate passive ad influence     |
| Attribution window analysis        | Assess how ad viewing affects conversion timing  |
| Platform comparison                | Identify which channels drive passive engagement |
