Cost Per Acquisition (CPA) is a digital marketing metric that measures the aggregate cost to acquire one paying customer or generate one conversion action through a specific campaign or channel. This performance-based pricing model is particularly common in affiliate marketing; paid search; and display advertising.
Calculating CPA is straightforward: divide the total cost spent on a marketing campaign by the number of acquisitions or conversions it generated. For example; if a campaign costs $5000 and results in 100 new customers; the CPA is $50 per customer.
CPA targets vary significantly by industry; product type; and average order value. Higher-priced products or services with larger profit margins can typically sustain higher CPAs; while businesses with slim margins need to maintain lower acquisition costs to remain profitable.
Digital marketers use CPA as a key performance indicator to evaluate campaign efficiency and determine which channels deliver the best value. This metric helps optimize budget allocation by identifying the most cost-effective acquisition sources.
Strategies for reducing CPA include improving targeting precision; enhancing landing page experiences; refining ad creative and messaging; implementing effective retargeting; optimizing bidding strategies; and testing different conversion paths to identify the most efficient approach.
