The power of word of mouth (WOM) communication and its influence on consumer decision making is well established in academic literature. The recent adoption of online communication by many consumers has facilitated a fundamental change to the structure of many WOM interactions by exposing consumers to electronic WOM (eWOM) from virtual strangers. The current study seeks to uncover whether traditional findings on social ties and WOM communication hold for eWOM information.

Data were collected from 482 college students with varying levels of expertise with eWOM forums, specifically RateMyProfessors.com in the USA. Participants completed a 20‐question survey related to university professor and class choice.

The study finds that students seeking information on which professor to take weight the information they obtain from eWOM forums to be equally influential in their decision as their own primary experience with the professor. Furthermore, the information gained from the eWOM forum is more influential in their decision than speaking with friends in person (WOM). While existing research suggests that strong tie referral sources are more influential than weak tie information sources on decision making, this research finds that some weak tie information sources are rated as more influential.

A limitation of the study is the focus on one eWOM forum, RateMyProfessors.com. Future research would benefit from expanding the number and type of eWOM forums.

While the emergence of the Internet and social networking has spawned an interest in the overall study of eWOM, this study is the first to evaluate eWOM in the context of tie strength, homophily and decision making. The study also investigates whether existing theories of interpersonal communication hold in an online context.

The purpose of this paper is to draw from the diffusion of innovations theory to explore multi-levels of influences (i.e. individuals, networks, news attributes) on news sharing in social media.

A survey was designed and administered to 309 respondents. Structural equation modelling analysis was conducted to examine the three levels of influential factors. These included self-perceptions of opinion leadership and seeking at the individual level, perceived tie strength and homophily at the network level, and finally, perceived news credibility and news preference at the news attribute level.

The results revealed that the influences of self-perceptions of opinion leadership, perceived tie strength in online networks and perceived preference of online news had significant effects on users’ news sharing intention in social media. However, self-perceptions of opinion seeking, homophily, and perceived news credibility were not significant.

This is one of the first studies on news sharing in social media that focus on diverse levels of influential factors. In particular, the research suggests the viability of the diffusion of innovations theory to explain this pervasive global phenomenon. Further, the influential factors identified may help to stimulate active participation in social media platforms and ultimately enhance the sustainability of these platforms.

The purpose of this paper is to examine the influence of various sources of negative electronic word-of-mouth (eWOM) and negative personal word-of-mouth (pWOM) on trust in the Word-of-mouth (WOM), attitude toward the service provider and purchase intention.

Data were gathered from 336 Moroccan workers who responded to an online survey.

Results show that negative pWOM is more influential than negative eWOM in the form of written Facebook testimonials, written review site testimonials and written testimonials on a corporate website. However, there is a relative ranking of importance among eWOM sources, with review site testimonials found to be more influential than either Facebook or corporate website testimonials.

This work responds to a call for research on differences and similarities between pWOM and eWOM. The findings extend understanding of the relative influence of negative pWOM and negative eWOM.

The results of this study provide guidance to service marketers in terms of strategies for deflecting negative WOM and allocating service recovery resources.

This study is the first to compare the relative influence of negative pWOM and eWOM in service consumption.

The purpose of this paper is to advance in research on consumer psychology of hospitality, since it investigates how online search behavior of users (particularly, information search and choice) is influenced by the opinions of other people in a new context characterized by the generalized use of Web 2.0 applications.

Empirical research was carried out in the hotel sector in Iberian Peninsula, where two Web 2.0 applications are especially relevant for users: the review Web sites and the hotel interactive Web sites. A qualitative method (in-depth interviews with hotel managers) and a quantitative technique (personal surveys to a sample of 830 users) were used to conduct this research.

The results indicates that the perceived influence on behavior of the user-generated content on these Web 2.0 applications is determined, in both cases, by the value of the information, the credibility of the sources and the degree of similarity between the user and the creators of content.

Firms should have an active presence in the review Web sites and the hotel interactive Web sites, and use these platforms for market research and communication. Firms should engage users to post content, support their credibility and facilitate the evaluation of the content generators’ similarity.

This paper is the first study in the hospitality literature that develops and empirically tests an integrative model explaining the perceived influence on behavior of user-generated content on Web 2.0 applications.

This study applies social network theory to examine the moderating effects of two online social media network characteristics, namely homophily and consensus, on the influence of negative electronic word of mouth (NeWOM) and of firm crisis response on consumer attitude toward a company.

Hypotheses were tested using a mixed-model experimental design of three between-subjects factors, including manipulations of homophily (high vs low), consensus (high vs low), and firm crisis response (accommodative vs defensive), and one repeated measure within-subjects factor of attitude toward the company at three different points in time (A₀, A₁, A₂). Data were collected from 328 Thai participants who were randomly assigned to one of the eight experimental conditions.

High homophily and high consensus online social media network conditions worsen the negative impact of NeWOM on consumer attitudes. However, high homophily and high consensus strengthen the positive influence of an accommodative response in regaining favorable attitude toward the company. Low homophily and low consensus negate the impact of the firm's defensive response, preventing any further deterioration of attitude toward the company.

Marketers need to understand the relational patterns among members of online social media networks in order to assess the extent to which consumers are influenced by others in the network. In doing so, the firm can better anticipate and manage the impact of NeWOM and can launch an appropriate response strategy that optimizes the recovery, or minimizes the deterioration, of lost company image and reputation.

This study provides a dynamic view of consumer attitudes and highlights the substantial impact that others in the online social media network have on consumers' evaluation of NeWOM and of firm recovery efforts.

The nature of digital media channels are important factors in explaining consumers’ behavior over the Web, and specifically on social network sites (SNS). The purpose of this paper is to propose a conceptual framework explaining consumer engagement with electronic word of mouth (eWOM) communication via SNS, based on key attributes of this media channel.

Based on the expectancy value theory (EVT), a conceptual framework is proposed to model the effect of eWOM channel attributes on eWOM engagement process. Consumer eWOM engagement is conceptualized as a second-order construct. A structural equation modeling procedure was employed to empirically test the model using data collected from two social media communication channels.

First, results suggest that engagement with eWOM can be conceptualized as a second-order construct based on user tendency to receive or share eWOM with other network members. Second, the path analysis model supports the employment of EVT and shows that two key attributes of eWOM channels, social capital and credibility, significantly affect consumer attitude toward eWOM via SNS. Attitude toward eWOM, in turn, affects eWOM engagement. Third, SNS channel type moderates the effect on attitude.

Marketing communication practitioners should note that the strength of social ties plays a key role in spreading eWOM on SNS effectively. This insight should be employed a part of social media marketing strategy.

This is first research that models the effect of social media attributes on eWOM engagement and demonstrates the moderating role of channel type. The model is highly valuable in light of the importance of the concept of engagement in internet research.

Despite the extensive academic interest in electronic word of mouth (eWOM) communication, consumer attitudes toward eWOM communication have been neglected. The purpose of this paper is to propose a conceptual framework for attitudes toward eWOM communication across digital channels.

Data were collected through a web-based survey on seven major digital communication channels. ANOVA was applied in order to analyze their differences. In addition, structural equation modeling was used to test the eWOM attitude model, using a sample of 864 participants who have had prior experience with the channels under study.

Findings indicate that both attitude toward eWOM and its antecedents significantly differ across channels. Additionally, a path analysis model reveals that the original integrated model applies to eWOM communications. Yet, in the case of eWOM, irritating messages may be positively related to attitude toward the channel, and credibility serves as a mediator of message value.

This paper supports the notion that attitude toward eWOM communication significantly differs across media channels. Future research should examine additional implications of attitude toward eWOM, and explore new and evolving channels.

Practitioners should adjust their eWOM media strategy to their objectives; blogs and social networks are more effective for brand attitude formation, whereas web forums enhance message credibility.

To the best of the authors’ knowledge, this is the first research study that tests attitudinal differences toward eWOM across digital channels. As such, it contributes to the understanding of people’s perception of these platforms.

The current study aims to examine esports consumers' social needs (inclusion, affection and control) as antecedents of positive eWOM intention. Additionally, the moderating effects of game playing type (individual-based competition vs. team-based competition) were tested to determine whether the inherent socializing opportunities provided by each game playing type have different effects on the relationship between social needs and eWOM communication of esports consumers.

A cross-sectional survey design was applied to 387 responses collected from an online survey platform. After checking several assumptions, a series of regression analyses were performed to test the suggested hypotheses.

The results revealed that the needs for inclusion, affection and control were positively associated with eWOM intention. Furthermore, the relationships between inclusion and eWOM intention and affection and eWOM intention were moderated by game playing type.

The current study extended the fundamental interpersonal relations orientation theory from conventional interpersonal relationships to interpersonal communication in online platforms. This research also suggested that eWOM communication in esports could be supplemental social opportunities, especially for individual-based competition games.

This study aims to examine the influence of homophily in an online community and the effect of electronic word of mouth (eWOM) consensus on young consumers’ attitudes.

This study implemented an experimental research design using a two (low/high homophily) × two (low/high eWOM consensus) mixed factorial design. This study explores young consumers’ changes in brand attitude after encountering negative eWOM.

The results indicate that a high consensus of negative eWOM among online community members leads to significant changes in attitude, while a low consensus of negative eWOM does not produce such an effect. Negative eWOM from either high or low homophilous sources produces significant changes in attitude. There are significant attitude changes when a strong consensus of negative eWOM is received from a source with a high level of homophily.

Service failures in offline service settings lead to the dissemination of negative eWOM on social media. To handle and prevent social media crises, researchers should understand online crises antecedents relating to information characteristics i.e. eWOM consensus and characteristics of online community members to evaluate the crises impact. Brands should monitor tone and dialogue of online community member on social media to remedy and diminish any damage done to their brand image from negative eWOM.

This study contributes to the application of social network theory by understanding the role of nodes on negative eWOM effect in social media.

The purpose of this paper is to investigate how today’s new type of opinion leaders, “Citizen Influencers” (CIs), persuade their followers by exploring which characteristics contribute to their persuasiveness.

Combining theories within opinion leadership, celebrity endorsement, product placement and user-generated content (UGC) five source characteristics – namely, expertise, trustworthiness, likeability, similarity and familiarity – are investigated using fashion as an example. A longitudinal netnographic study of ten CIs and their UGC and six focus groups with followers of specific CIs on Instagram are conducted.

All five characteristics contribute to the persuasiveness of CIs with trustworthiness as the main contributor. CIs persuasiveness lies in their unique ability to encompass two opposing qualities simultaneously: being attainable and relatable like ordinary consumers; being taste leaders with superior, celebrity-like status.

Only qualitative studies within the fashion category have been conducted, wherefore the relative weight between the two qualities cannot be quantified.

When choosing a CI, managers may consider: the amount of followers per CI as an indicator of influence; similarity between follower and CI as it provides the basis for trust; and the CIs personal universe on their Instagram profile as it leverage the meanings associated with the brand.

The key driver of CIs persuasiveness is their trustworthiness which mediates and amplifies the effect of the other four characteristics. CIs’ persuasive power rests upon the balancing act of being relatable and aspirational.
