Blended Cost per Conversion measures the average cost for each conversion attributed to your ads. Google Ads is the only platform that reports conversions, so only Google spend counts.

​
Formula

Blended Cost per Conversion = Google Spend ÷ Blended Conversions

Formula Components

​
Example

Your store ran ads on all three platforms in April: Dividing Blended Spend ($18,000) by Google’s 380 conversions would give $47.37, three times what Google actually spent per conversion.

​
How It Works

Upstack divides Google spend by the conversions Google Ads reports. Meta and TikTok don’t fill the conversions count, so their spend is left out. In the app the formula reads Google Spend ÷ Conversions. Because Google is the only source, this metric matches Google Cost per Purchase for the same filters. For Meta and TikTok results, use their own purchase or action metrics.
