Google Cost per All Conversions measures how much you spend on average to drive each conversion action across all goal types in Google Ads.

Example

Your brand awareness campaign spent $3,200 in March and generated 640 all conversions (including purchases, sign-ups, and video views).

Campaign	Spend	All Conversions	Cost/All Conv.
Brand Awareness	$3,200	640	$5.00
Retargeting	$1,800	450	$4.00
Shopping	$4,500	300	$15.00

How It Works

Google calculates this metric by dividing your total ad spend by the number of all conversions recorded. Unlike standard cost-per-conversion, this includes every conversion action—purchases, leads, phone calls, app installs, and micro-conversions like video engagement or page views.
