More and more online feedback is being relied upon to make choices about the purchases and services we use daily. Conversely, companies rely on online reviews to find new customers and understand how people perceive them. Therefore, the online reviewing process and all its entities and processes are salient. Hence, in this research, we analyse online review related trends in research between the years 2000–2021 with an inductive categorization of 181 articles, in over fifty leading academic outlets. Using this categorization, we next investigate trends in the discussion and research on the online reviewer, online review, and review reaction. From these trends, we develop a nomological a-priori net of the online review process. Further, we discuss, some limitations of the current literature, posit research directions for future scholars and address the gaps in the current research on the online review process.
