Discussion
Our holistic, conceptual framework sheds new light on online platform business models by combining three distinctive revenue sources (i.e., search advertising, display advertising, and membership fees) and buyer- and seller-side strategies. With a unique quasi-experiment, we examine which buyer traffic generation and seller engagement strategies generate the most, in terms of each revenue source, as well as how their effectiveness shifts due to an upmarket repositioning strategy. Our findings produce both theoretical and managerial insights.
Theoretical Implications
This study offers a comprehensive framework with respect to three different platform revenue streams, each operating in a different way (Fig. 1). With the recognition that “many online businesses combine multiple revenue streams” (Lambrecht et al. 2014, p. 332), yet that most extant findings focus on individual revenue sources (Fang et al. 2015; Tucker and Zhang 2010) or on an aggregate level of revenues (Grewal, Chakravarty, and Saini 2010; Zhang et al. 2012), this article offers a more complete picture of online platform business models.
