What is CPA (Cost per acquisition)?
Cost per acquisition (CPA) is the average cost of acquiring one customer through a marketing channel. It is calculated by dividing total ad spend by the number of conversions. Lowering CPA is a primary goal of performance marketing. UGC-style ad creative and high-volume creative testing are proven strategies for reducing CPA on paid social platforms.
