This study aims to understand the role of E-Commerce in building customer loyalty, explain the process of loyalty formation, and assess how customers perceive service quality in relation to loyalty, using the GoFood service in Jombang as a case study. The rapid growth of online food delivery services has intensified competition, making customer loyalty a critical factor for sustainability. Employing a qualitative case study approach, data were collected through in-depth interviews with 30 GoFood customers and several drivers in the Jombang area. The findings reveal that E-Commerce platforms significantly enhance loyalty through user-friendly application interfaces, supporting features (such as live tracking, history, and digital payments), and beneficial promotions. The loyalty formation process occurs gradually through consistent positive experiences, moving from customer satisfaction to trust, and ultimately to habitual use. Crucially, the quality of driver services—including politeness, effective communication, punctuality, and order accuracy—emerged as a key determinant of customer comfort and repeat orders. This study implies that for E-Commerce platforms to maintain a competitive edge, strategies must integrate digital convenience with consistently reliable human interactions. The research contributes empirical insights from a semi-urban Indonesian context, highlighting that customer loyalty is not merely transactional but is built on a combination of technological ease, economic value, and positive interpersonal service experiences.

Customer satisfaction is a central issue in marketing management, as it plays a crucial role in determining customer loyalty amid increasingly intense business competition. A comprehensive understanding of the factors influencing customer satisfaction is essential not only for academics in strengthening marketing theory but also for practitioners in designing effective service and product strategies. This article aims to address two research questions: (1) what are the dominant factors influencing customer satisfaction, and (2) how does customer satisfaction relate to customer loyalty? The study employed a qualitative literature review method. The data consisted of scientific articles published between 2020 and 2025, accessed through Google Scholar and Publish or Perish (PoP) using the keyword “customer satisfaction.” From an initial selection of 30 articles, 27 were identified as relevant, and 5 core articles were further analyzed. The findings reveal three main themes: product and service quality as the dominant determinants of customer satisfaction; price, brand image, and promotion as supporting factors; and customer trust as an important mediating variable in building loyalty. This study concludes that customer satisfaction serves as a strategic link between service quality and customer loyalty. Future research is encouraged to explore the roles of digitalization, customer experience, and sustainability in shaping long-term customer satisfaction.

Customer satisfaction and loyalty are central issues in marketing management, as both play crucial roles in ensuring business sustainability amid increasing competition.

This study explores the influence of digital marketing, service quality, and product innovation on customer satisfaction among Skintific skincare consumers on TikTok Shop. Employing a quantitative, explanatory research design, the study used purposive sampling to collect 200 valid responses from consumers who had purchased Skintific products via TikTok Shop. Data were collected through an online questionnaire and analyzed using multiple linear regression with SPSS, preceded by validity, reliability, and classical assumption tests. The results revealed that product innovation had the most significant impact on customer satisfaction (β = 0.589, p < 0.001), followed by service quality (β = 0.343, p < 0.001). However, digital marketing did not have a significant direct effect on customer satisfaction (β = 0.019, p = 0.746). The model explained 86.9% of the variance in customer satisfaction (R² = 0.869), indicating strong combined effects from the three factors. These findings suggest that post-purchase factors, particularly product innovation and service quality, are more decisive in influencing customer satisfaction than promotional efforts alone. Managerial implications highlight the importance of continuous product development, enhancing service responsiveness and reliability, and integrating digital marketing with value delivery to optimize customer satisfaction. The study contributes to social commerce literature by clarifying the distinct roles of marketing, service quality, and innovation in the context of TikTok Shop, providing both theoretical insights and practical guidance for brand strategy in social commerce platforms. This research adds to the understanding of how businesses can strategically leverage product innovation and service excellence to enhance consumer satisfaction and foster long-term customer loyalty in the competitive social commerce landscape.
