What is Cost Per Acquisition (CPA)?

Cost Per Acquisition (CPA) is a critical marketing metric that measures how much it costs your business to acquire one paying customer through your marketing efforts. It's calculated by dividing your total marketing spend by the number of conversions or acquisitions during a specific period.
