By default, revenue per ad is defined as
Revenue per Ad = Purchase Conversion Value / Ad-Count in selected timeframe
If you use a revenue metric other than "Purchase Conversion Value", e.g. because you use an attribution platform such as adtribute or TripleWhale, you can easily swap it out.
To do this, navigate to the "Home" page and click on the “Edit” button under "Revenue per Ad".
A pop-up window will open where you can easily replace the revenue metric with another metric.
