CPA is often a key indicator for campaign performance, but without any adjustments, it can be inadequate in measuring how much your Perfect Audience campaigns assist with achieving your conversion goals.
For this reason, we’re introducing the concept of Conversion Attribution Rates. You can now set a Conversion Attribution Rate for your Perfect Audience site’s post-click and post-view conversions on your site setting’s page (under Manage > Site Settings). These percentages represent the value your company places on the ad view or ad click that precedes a customer converting on your site.
We use your Attribution Rate settings to calculate an adjusted CPA (aCPA), which you will now see in your Perfect Audience dashboard. As it takes into account how much your Perfect Audience campaigns are assisting with your conversions, the resulting aCPA is a much more meaningful indicator of your campaign performance.
