As social media platforms (e.g., Facebook) and related online communication channels (e.g., review websites and community forums) grow in quantity and commercial orientation, marketing practitioners and scholars alike have recognised the importance of understanding and influencing online consumer communication processes. Specifically, it is suggested that online opinion leaders (‘Epinion leaders’) can be utilised as a target group to manage negative e-word-of-mouth (‘e-WOM’) and e-complaints. This study identifies and targets Epinion leaders and explores three central personality characteristics – altruism, self-confidence and the need for uniqueness – as a means of understanding Epinion leaders’ motivations to communication and tailoring corporate communication campaigns. The study focusses herby on the rapidly growing and increasingly influential 50-years+ e-commerce segment (i.e., ‘silver surfers’). Based on an online survey of 1,700 e-consumers aged 50 years and older, the proposed structural equation model verifies the positive influence of Epinion leadership on the propensity to spread negative e-WOM and e-complaints while demonstrating the applicability of personality characteristics as means of influencing consumers’ online communication strategies. The findings demonstrate that addressing consumers’ self-confidence can be an essential way of reducing negative e-WOM and encouraging e-complaints, which show opposing effects on customer satisfaction. For practitioners, this study emphasises the usefulness of negative Epinion leaders as a target group and recommends fostering consumers’ self-confidence in order to prevent negative online opinion-cascades and increase overall satisfaction.

Customers often rely on peers’ opinions and experiences when forming expectations and evaluating a service provider. New media channels such as consumer review platforms and social networking sites help customers obtain firsthand information from other customers to evaluate a service. Prior research confirms the effects of positive electronic word of mouth (eWOM) on recipients, yet less is known about how companies should respond to negative eWOM. The authors conducted a series of experimental studies in the context of new media online channels (i.e., consumer review sites and social media brand pages) to investigate the effects of various company response strategies on consumers’ perceptions. The results have two implications for service firms: First, adequate response strategies to negative eWOM compensate for the negative effects that occur when Internet users attribute responsibility to the firm. Second, the findings indicate that firms need both adequate response strategies and an engaged community to restore their perceived trustworthiness in consumers’ eyes.

Online advertisers use multiple channels to reach consumers on the Internet. However, little is known on the interplay between online advertising channels. To fill this gap, this study provides a comprehensive overview of interaction effects in online advertising for individual consumers, including not only site visits, but also exposures that do not directly lead to a click. Based on a large cookie-based individual-level data set the authors analyze interaction effects within and between channel groups on purchase behavior. By classifying online marketing channels along the dimensions of initiation locus and previous brand awareness, they find significant interactions between contacts within and across channel types. While clicks following contacts in customer-initiated channels that require brand awareness overall have a negative effect on purchase propensity, previous clicks in firm-initiated channels positively interact with clicks in customer-initiated channels. The results can help managers to coordinate marketing strategies, optimize campaigns, and develop individualized marketing and targeting approaches.
