The document discusses market segmentation strategies for different product categories. It provides examples of segmenting the sanitary napkin, shampoo, and mobile phone markets based on behavioral, demographic, and psychographic factors. For sanitary napkins, the core segments are based on usage occasions - daily use, special occasions like after birth, and use during menstruation. Shampoo segments are primarily behavioral based on benefits sought, such as hair health, anti-dandruff, and smoothness. Mobile phones can be segmented according to motivations and technology knowledge into groups like optimum seekers, basic function seekers, technology freaks, and budget-conscious durability seekers.
