Online customer ratings are ubiquitous in e-commerce. However, in presenting these ratings to consumers, e-commerce websites utilize different formats. The purpose of this paper is to investigate the effects of customer ratings formats on consumer trust and processing fluency.
Drawing on the latest behavioral research, two empirical experimental studies test whether the format of online customer ratings affects consumer trust and processing fluency.
The studies offer converging evidence that a simpler ratings format (i.e. mean format) elicits higher processing fluency and, in turn, higher consumer trust than does a more complex ratings format (i.e. distribution format).
Future research could include additional factors that might influence the ease of online ratings processing for consumers. Investigation of possible moderators, such as need for cognition, numeracy and consumer involvement, may also be of value.
These findings have timely practical implications for the design and presentation of customer ratings to enhance e-commerce outcomes.
This paper extends the effects of processing fluency on consumer trust to the increasingly important context of e-commerce. In doing so, it highlights important interactions between the evolving information environment and consumer judgment. The key takeaway for managers is that simpler online customer ratings formats help to enhance consumer trust.
