Google Purchases is the total number of purchase conversions that Google attributes to your ads.
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.
