Usage segmentation divides consumers into groups based on their consumption patterns and rates of a product. It categorizes consumers as non-users, light users, medium users, or heavy users. Companies then target specific usage groups, often focusing on heavy users who provide the most revenue. Usage segmentation is demonstrated through products packaged in different sizes tailored to consumption levels, like shampoo in travel sachets or Maggi noodles in multipacks. It aims to meet the top 20% of customers who generate most of the turnover according to the Pareto principle. Seasonal sales also exemplify usage segmentation by targeting products to demand cycles.
