Formula

Google Purchases = COUNT ( Purchase Conversions )

Example

A fitness equipment store ran $12,500 in Google Ads last month:

Campaign	Purchases	Spend	CPA
Brand Search	187	$2,800	$15
Shopping	124	$5,200	$42
Performance Max	89	$4,500	$51
Total	400	$12,500	$31

How It Works

Google tracks purchase conversion events triggered by users who interacted with your ads. This count is pulled directly from the Google Ads API and reflects Google’s attribution model for determining which purchases resulted from your advertising.
