Example

A home goods retailer spent $12,450 on Google Ads in March across their campaigns:

Campaign	Spend	Share of Budget
Shopping - Best Sellers	$5,200	42%
Search - Brand Terms	$3,100	25%
Performance Max	$2,850	23%
Display Remarketing	$1,300	10%

How It Works

Google Spend is pulled directly from the Google Ads API and represents actual charges to your account. This includes all costs across Search, Shopping, Display, Video, and Performance Max campaigns. The metric updates as Google processes billing events.
