Definition
Customer segmentation is the practice of dividing a company’s customer base into distinct groups based on shared characteristics. These characteristics may include demographics, geographic location, purchasing behavior, needs, or psychographics such as lifestyle and values. Segmentation allows businesses to tailor marketing strategies, product offerings, and communication to better serve each group.
For example, a retailer may segment customers into frequent shoppers, seasonal buyers, and first-time purchasers. Each segment receives personalised offers that match their buying habits.
Advanced
Advanced segmentation uses data analysis, machine learning, and predictive modelling to create highly specific groups. Instead of relying only on demographics, businesses combine behavioral data, transaction history, and engagement metrics to build richer customer profiles. This leads to micro-segmentation, where even small groups can be targeted with precision.
Segmentation is often integrated with CRM systems, marketing automation platforms, and customer data platforms. Techniques such as RFM (Recency, Frequency, Monetary) analysis, clustering algorithms, and lookalike modelling help refine segments for targeted campaigns. Effective segmentation also supports customer journey mapping, retention strategies, and lifetime value optimisation.
