The effects of word-of-mouth consistency on persuasiveness

Word of mouth (WOM) consistency can be readily observed in online product evaluations. Previous studies on the influence of WOM consistency on purchase intentions have showed contradictory results. In this research, we identify how stronger persuasiveness of WOM is achieved when consistency, product type, and review content work together. Study 1 shows that regarding search goods, highly consistent factual reviews are more persuasive. Study 2 shows that concerning experience goods and credence goods, highly consistent experiential reviews have greater persuasiveness. However, low WOM consistency can also achieve stronger persuasiveness under some circumstances. Moreover, in Study 3, we replicate our findings and explore the possible underlying mechanism.
