# Blended Cost per View-Through Conversion: VTC Acquisition Cost

> Track your cost per view-through conversion across all channels. Measure how much you spend for each conversion from users who saw but didn't click your ads.

<Tip>
  Blended Cost per View-Through Conversion measures how much you spend on average for each view-through conversion—where a user saw but did not click your ad before converting.
</Tip>

## Formula

<Info>
  **Blended Cost per View-Through Conversion** = **Blended Spend** ÷ **Blended View-Through Conversions**

## Example

Your store spent **\$15,000** across all advertising channels in May and generated **312 view-through conversions**.

| Channel     | Spend        | VT Conversions | Cost/VTC    |
| ----------- | ------------ | -------------- | ----------- |
| Meta        | \$8,000      | 180            | \$44.44     |
| Google      | \$5,000      | 92             | \$54.35     |
| TikTok      | \$2,000      | 40             | \$50.00     |
| **Blended** | **\$15,000** | **312**        | **\$48.08** |

## How It Works

Blended Cost per View-Through Conversion aggregates total ad spend and view-through conversions from Meta, Google, and TikTok, then calculates the average cost per VTC. View-through conversions are attributed when a user sees your ad, does not click, but converts within the platform's attribution window. This metric helps quantify the cost efficiency of your passive brand awareness efforts.

| Measuring brand awareness ROI                       | Compare VTC cost to click-through CPA                                     |
| Evaluating display/video campaigns                  | Assess cost efficiency of impression-driven conversions                   |
| Budget allocation for awareness vs. direct response | Balance spend based on VTC vs. click-based acquisition costs              |
| Platform comparison                                 | Identify which channels deliver view-through conversions most efficiently |
