IAB Polska/PwC01/2026Poland
A metric measuring the cost of achieving a desired campaign result, such as a lead, purchase, registration, or download. The definition of the action must be clearly specified before reporting begins.
Why it matters
It measures what you actually buy in a campaign: the cost of one acquisition — a lead, purchase, or registration. It enables comparing channels by actual results, not just clicks.
What's missing without it
Without cost per acquisition, campaigns are evaluated by reach and clicks — which can be cheap and worthless at the same time.
When it is used
When billing performance campaigns and comparing channel ROI; the action definition is set before launch.
How we use it
The report shows the average CPA for lead acquisition from landing page campaigns and social media ads.
