Abstract
Customers are not created equal. However, segmenting customers in terms of their profitability is still an underutilized approach in marketing nowadays. Many E-commerce sites still apply the same customer cares to all customers without calculating whether the expected profit from a customer is greater than the marketing cost to her or not. In this paper, a decision theoretic approach to segmenting customers based on RFM (Recency, Frequency, and Monetary) Model and Network value has been proposed here.
