ABSTRACT This article aims to examine the effects of different features of various eWOM (electronic word-of-mouth) platforms on consumers’ perceived credibility of eWOM regarding the product-related risks. Based on the stimuli–organism–response (S–O–R) theory, this study establishes a model to explore the relationships among eWOM platforms, tie strength, social cues, and perceived eWOM credibility. A mixed design of 2 (eWOM platforms) × 2 (product-related risks) conditions experiment and a survey method is applied to verify the model. The results show that tie strength between eWOM publishers and recipients positively influences the perceived eWOM credibility. The volume of social cues in eWOM platforms positively influences the perceived credibility of a female, while the opposite is true for a male. Both tie strength and volume of social cues in social media are greater than those in e-commerce websites. For products with low risks, eWOM in e-commerce websites is perceived to be more credible. Findings implicate that interactive functions should be added to the product comment area to enhance communications between the reviewers and potential consumers. Findings also encourage the cooperation between e-commerce websites and social media and suggest that managers should develop proper strategies in different situations.
