Abstract:

Customer loyalty remains a central construct in marketing, yet its relevance and conceptualization are increasingly challenged by digital transformation and evolving business models. This study aims to critically and comprehensively examine the evolution, antecedents, and measurement of customer loyalty within profit-oriented firms across service, trading, and industrial sectors. A narrative literature review approach was employed by analyzing 65 peer-reviewed articles published between 2021 and 2025, sourced from Scopus and Web of Science databases. The review adopts a thematic mapping strategy to synthesize fragmented perspectives and identify emerging research trends. The findings reveal that customer loyalty has shifted from a traditional focus on repeat purchase behavior and attitudinal commitment toward a multi-dimensional construct shaped by digitalization, platform-based ecosystems, and organizational capabilities. Key antecedents of loyalty extend beyond satisfaction and trust to include innovation, dynamic capabilities, digital transformation, and sustainability practices. Furthermore, the study identifies significant limitations in traditional loyalty measurement approaches, highlighting the need for new metrics that capture engagement, multi-channel interactions, and ecosystem participation. This study contributes to the literature by integrating diverse theoretical perspectives and proposing a more holistic understanding of customer loyalty in contemporary markets. It also highlights critical research gaps, particularly regarding the role of digital platforms, algorithmic influence, and cross-context variations in shaping loyalty. The findings offer important implications for both researchers and practitioners. Future research should focus on developing integrative frameworks and context-sensitive measurement models, while managers are encouraged to adopt data-driven, personalized, and sustainability-oriented strategies to foster long-term customer loyalty.
