1. Loyal customers: They will establish psychological characteristics unrelated to price factors because of long-term trust, that is, low price sensitivity. 2. Potential customers: This kind of customers need to be prompted to turn to the first type of customers in the service because of their short contact time. 3. Marginal customers: The contribution value and purchasing power of these customers to the store are relatively low and need to be fully tapped. 4.

In daily communication with customers, we can try to establish corresponding labels for customers and classify them. This is not only an effective way to identify customers or potential customers, but also the application of strategic resource allocation and tactical service marketing countermeasures in customer management, which supports enterprise's customer-centered personalized service and professional marketing.

Customer classification can analyze customer's consumption behavior and consumer psychology. Enterprises can provide different product contents for customers with different behavior patterns and different promotion methods for customers with different consumption psychology.

Customer classification is also the basis of other customer analysis. Mining in classified data is more targeted and can get more meaningful results.
