A customer segment is a group of individuals or entities within a broader market that share common characteristics, needs, behaviors, or attributes. These segments are identified through criteria such as demographics, psychographics, geographic location, buying behavior, or product usage patterns. By understanding and categorizing customers into specific segments, businesses can adjust their marketing efforts, product offerings, and services to better meet the demands of each group. This segmentation allows companies to target their marketing strategies effectively and improve business performance by addressing the preferences and requirements of each segment.
