The Influence of Reviewer Demographic Information Provision on Trust and Purchase Intent for Users of Online Websites

E-commerce websites are increasingly interested in how to effectively utilize online reviews to positively influence consumer decisions. One potential mechanism is providing socio-demographic information about reviewers along with the reviews. This study investigates how consumer decision outcome variables (e.g., perceived usefulness, trust and purchase intent) change when reviewers' age and gender are provided and when a consumer's and reviewer's age/gender are same or similar. The hotel industry was utilized as the context. The results from the experiment showed that, regardless of the compatibility of the provided demographic information (reviewers' vs. consumers'), providing reviewers' age and gender positively impacted consumers' perceived online trust, and about half of the participants processed and remembered the demographic information. It was additionally noted that people who could remember reviewers' demographic information had not only more trust in the reviewer, the specific company's website, and the specific hotel itself, but also higher intention to recommend and book the hotel.
