RFM stands for Recency, Frequency, and Monetary Value, and is a marketing strategy used to analyze and segment customers based on their purchasing behavior. It takes into account how recently a customer has made a purchase, how often they make purchases, and how much money they spend on each purchase. This information is then used to identify and target high-value customers, as well as to personalize marketing efforts and improve customer retention. RFM analysis is a valuable tool for businesses looking to optimize their marketing strategies and increase customer loyalty.
