ABSTRACT
Review sites play a key role in determining the reputation and popularity of various businesses. Consumers are influenced by the reviews on these sites to take their decision before adoption of a service, rendering significant potential to reviewers on these sites to hurt or boost the practise of business units. It is usually believed that the local reviewers have a better understanding of the business hosts in their regions and their reviews are much more influential. How-ever by analyzing the reviews on a popular review site Yelp, we show that the reviews provided by the non-local review-ers (“outsiders”) converge over time while local reviewers are much more decentralised and provide mixed choices to the consumers. In order to identify the possible reasons for this, we unfold a series of systematic differences in the reviewing characteristics of the outsiders that make them strikingly different from the insiders.
