After theoretical considerations, a research model was developed and empirically tested. The results show that there are differences in the preferences of niche providers and market leaders, such as importance of website features and the breadth and depth of a balanced product portfolio of customers. In addition, the study shows how individual factors can be analyzed in an online shop and which alternative courses of action can be derived.
