Cost Per Acquisition
pol. CPA
CPA (Cost Per Acquisition) is the cost to acquire one customer or one conversion through advertising. It's one of the most important campaign efficiency metrics — if your CPA is lower than your product margin, you're profitable. CPA differs from CPM (cost per impression) and CTR (click rate) in that it measures actual business outcome: how much it costs to acquire one paying customer.
