Blended Cost per All Conversions: True Acquisition Cost

Blended Cost per All Conversions measures the average cost for each conversion, including cross-device and view-through conversions. Google Ads is the only platform that reports all conversions, so only Google spend counts.

Formula

Blended Cost per All Conversions = Google Spend ÷ Blended All Conversions

Formula Components

Metric	Definition
Google Spend	Spend from your Google Ads accounts. Meta and TikTok spend are left out
Blended All Conversions	All conversions, including cross-device and view-through, as Google Ads reports them

Metadata
Type	Currency
Data Source	Google Ads
Aggregation	Ratio

Example

Your store ran ads on all three platforms in May:

Channel	Spend	All Conversions	Counted in this metric
Google	$8,500	640	Yes
Meta	$12,500	Not reported	No
TikTok	$4,000	Not reported	No
Blended Cost per All Conversions	$8,500	640	$13.28

Dividing Blended Spend ($25,000) by Google’s 640 conversions would give $39.06, nearly three times the real cost.

How It Works

Upstack divides Google spend by the all conversions count Google Ads reports. Meta and TikTok don’t fill this count, so their spend is left out. In the app the formula reads Google Spend ÷ All Conversions. Because Google is the only source, this metric matches Google Cost per All Conversions for the same filters.
