Global market segmentation is a cornerstone of effective international marketing strategy, enabling firms to identify, understand, and serve heterogeneous consumer groups across national borders. As globalization intensifies and markets become increasingly interconnected, organizations face growing pressure to balance global efficiency with local responsiveness. This paper provides an in-depth examination of global market segmentation, focusing on its conceptual foundations, segmentation bases, methodological approaches, and strategic relevance. Particular emphasis is placed on the challenges multinational enterprises encounter when segmenting global markets, including cultural diversity, data comparability, and dynamic consumer behavior. At the same time, the study highlights emerging opportunities created by digital technologies, data analytics, and evolving global consumer lifestyles. By synthesizing prior research and proposing an integrative conceptual framework, this paper contributes to international marketing literature and offers practical guidance for managers seeking to implement effective global segmentation strategies.
