Total ad spend is the sum of what you spend on paid advertising: Meta Ads, Google Ads, marketplaces, digital media, and any other channel where you pay to appear.

It serves as the basis for calculating key metrics such as ROAS (return on ad spend), CAC (customer acquisition cost), and CPA (cost per acquisition).

Why does it matter?

Without knowing your total investment, you can't tell if advertising is profitable. Looking at each platform separately gives you an incomplete picture: customers usually see ads in several places before making a purchase.

The important thing isn't to spend less, but to spend better. That means aligning your investment with what it actually generates: new customers, repeat purchases, and incremental revenue.

How is it calculated?

Formula: Total advertising spend = the sum of spending across all platforms and paid campaigns for the period.

For example, if in a given month you spend $3,000 on Meta Ads, $2,000 on Google Ads, and $1,000 on marketplace ads, your total advertising spend is $6,000.

Story mode

An online sports store invests in Meta Ads and Google Ads every month. Upon reviewing the data, it discovers that a large portion of its budget is being spent on ads that reach people who are already frequent customers and who would have made a purchase anyway. It decides to exclude them from those campaigns and use that money to reach people similar to its best customers.

• Synchronized audiences: You send your audiences to Meta Ads and Google Ads to run retargeting or lookalike campaigns using your own data, thereby targeting your ad spend more effectively.
• Precise segments: You can exclude or include customers based on their stage in the customer lifecycle, their RFM segment, or their cluster.
