Behavioral segmentation is a method that divides a market into distinct groups based on customers’ observed or reported purchasing or consumption behaviors. It considers various criteria such as frequency, volume, places of purchase, consumption methods, channels used, as well as online interactions and reactions to marketing communications. This approach allows marketing strategies to be adapted to consumers’ actual habits and preferences. With the development of the internet, behavioral segmentation has been strengthened by the ability to precisely track user actions, particularly in e-commerce and email marketing.
