The Impact of SAS Customer Experience Analytics on Lotte.com's Online Retail Success Implementing data-driven strategies is crucial for modern online retailers seeking to enhance customer experience, improve marketing efficiency, and increase sales. This paper analyzes the case of Lotte.com, Korea’s leading online shopping platform, which adopted SAS for Customer Experience Analytics to gain deeper insights into customer behavior and optimize its web traffic management. The discussion encompasses the background of Lotte.com’s initiative, identifies the main issues addressed, explores the analytical approach used, and evaluates the outcomes and strategic implications of this technological adoption. Context and Background Information Lotte.com, with its extensive customer base comprising approximately 13 million users and nearly one million daily visitors, faced the challenge of comprehensively understanding web traffic and consumer behavior to stay competitive in Korea’s burgeoning e-commerce market. Prior to the implementation of analytical tools, the platform relied on basic metrics that limited insights into customer engagement and shopping patterns. Recognizing the necessity for a sophisticated solution, Lotte.com introduced SAS for Customer Experience Analytics—an innovative system in Korea designed to track, analyze, and respond to complex behavioral data in real-time. This integrated analytics platform enabled Lotte.com to monitor detailed visitor activities, including page view trends, click preferences, and product popularity. It also facilitated precise measurement of campaign effectiveness across different marketing channels. The shift toward a data-centric approach allowed the company to uncover 'inconvenient truths'—truths that challenged prior assumptions about customer interaction and campaign success. This demonstrates the strategic importance of leveraging advanced analytics not only to recognize successful tactics but also to identify areas needing improvement. Identification of the Main Issues/Problems The core issues faced by Lotte.com prior to adopting SAS analytics involved limited visibility into actual customer engagement and a lack of detailed behavioral insights. Traditional metrics primarily focused on sales and order volume, ignoring critical aspects such as customer navigation paths, points of abandonment, and channel-specific performances. Consequently, the company struggled to optimize marketing campaigns or enhance the website’s usability based on nuanced data insights.
