With the explosion of internet users, there are many enterprises and organizations that regard the internet as the great marketing superhighway. Although fascination and speculation surrounds the impact of the cyber shopping mall on consumer shopping behavior, there is little empirical evidence underlying all this speculation. This article reports on the critical issues that consumers found salient as they browsed through cyber shopping malls. We gathered consumers’reactions via open-ended survey. We relate the reactions to the factors of tangibility, assurance, responsibility, empathy, and reliability which we had identified from the existing literature on service quality. Two additional questionnaires were administered to translate these factors to the cyber shopping mall context and to explore their relative salience. We also evaluated SERVQUAL and SERVPERF as service quality measures for cyber shopping malls. The results show that SERVPERF seems more promising than SERVQUAL. The results also suggest that cyber shopping mall merchants need to think more about how they perform on the issues known to affect customers’decision making for purchasing. We offer advice for enhancing the design of cyber shopping mall.
