Understanding CPA helps businesses evaluate the effectiveness of their marketing strategies and budget allocation. A lower CPA indicates that a company is efficiently acquiring customers, while a higher CPA may signal the need for adjustments in marketing tactics. By analyzing CPA, businesses can make informed decisions to optimize their spending and improve overall profitability.
