How credibility affects eWOM reading: The influences of expertise,trustworthiness, and similarity on utilitarian and social functions

In online information settings, a few people tend to contribute, while the majority of people consume. For this latter group of readers, electronic word of mouth (eWOM) provides information about products or service experiences that rarely are available from manufacturer-controlled sources, which makes this source of information especially helpful. In turn, eWOM influences readers' attitudes, intentions, and behavior. Manufacturers also hope to monitor and positively influence eWOM content, such as by supporting and building brand communities. But eWOM readers might doubt the credibility of information if it is mostly positive, and the usefulness of eWOM information depends on its credibility. This study offers an empirical and theoretical validation of how specific utilitarian and social functions of eWOM affect attitudes toward and intentions to read eWOM. In particular, trustworthiness is the most important credibility dimension; it affects both functions. Perceived expertise also enhances the utilitarian while similarity improves the social function of eWOM.     

eWOM across channels: comparing the impact of self-enhancement,positivity bias and vengeance on Facebook and Twitter

Abstract

When sharing personal details, versus talking about others, consumers tend to accentuate the positive experiences they have with brands in order to self-enhance amongst friends. Consumers also take vengeance on brands in public venues. Turning to social network sites (SNSs), it is unclear which is dominant. Here historical Facebook and Twitter eWOM (n = 47,907) is analyzed for a static group of 783 active US consumers. Self-enhancement is found on both SNSs. The majority of eWOM is positive Vengeance was rare, occurring only in 10.3% of all eWOM. eWOM appears to mirror a consumer's non-eWOM sentiment valence across SNSs. In this cross-platform comparison we suggest that SNS affordances alter eWOM creation Facebook has privacy expectations and limits direct brand interactions. Twitter is a public platform with less privacy expectations and a larger customer service component. Here eWOM is more prevalent on Twitter but contrary to our expectations is more positive.     

Examining Biased Assimilation of Brand-related Online Reviews

This paper examines the impact of pre-existing brand attitudes on consumer processing of electronic word-of-mouth (eWOM). This topic is particularly important for brands that simultaneously possess strongly pronounced proponents as well as opponents. Two experimental studies using univalent (study 1, N = 538) and mixed (study 2, N = 262) sets of online reviews find indications for biased assimilation effects of eWOM processing. Consumers perceive positive (negative) arguments in online reviews as more (less) persuasive when having a positive (negative) attitude towards the brand. Perceived persuasiveness in turn influences behavioral intentions and acts as a mediator on the relationship between attitude and behavioral intentions. We examine two moderators of this effect. When priming individuals to focus on other consumers (vs. a self-focus prime), the biased assimilation effect is weaker (study 3a, N = 131). In contrast, we show that biased assimilation becomes stronger under conditions of high (vs. low) cognitive impairment (study 3b, N = 124). Our findings contribute to the literature on the relationship between eWOM and brands and advance our understanding of potential outcomes of brand polarization.     

Examining the relationship between language divergence and word-of-mouth intentions

More than half of the countries in the world are multilingual, and more than half the world's consumers speak more than one language. Thus, bilingual consumers often receive services provided in a second or nonnative language. This article examines these consumers' word-of-mouth intentions after a service provision in a second language. Two studies show that consumers served in a second language are less likely to spread positive word of mouth. The results also reveal a negative halo effect, such that consumers served in a second language perceive the service provider as less responsive in general. Furthermore, the service provider's perceived responsiveness appears far more important for determining positive word-of-mouth intentions than other factors, such as service reliability. This study therefore contributes to the fields of service and sociolinguistics, with important implications for managers as well.     

Aggregate consumer ratings and booking intention: the role of brand image

The very nature of tourist services implies that consumers consider all available cues when making hotel bookings. Information obtained via the Internet is an especially important cue, and the findings of numerous studies highlight the importance of peer-generated information—electronic word-of-mouth (eWOM)—in consumers’ decision-making processes. Along with eWOM, however, traditional marketing signals such as brand image and price still affect consumer behaviour. Thus, this study analyses the effect of eWOM (i.e. global hotel ratings) on purchase intention, considering the role of brand image. Two online scenario-based experiments designed using real information from TripAdvisor were conducted. The final sample comprised 260 participants. Variation in hotel ratings modified consumers’ purchase intentions, with brand image playing a significant role in this relationship. The effect of eWOM on consumer purchase intentions was higher (lower) for hotels with a poorer (better) brand image. The results of the analysis imply that price can potentially help to prevent the negative effect of poor ratings.     

Cutting Through the Online Review Jungle — Investigating Selective eWOM Processing

Consumers frequently rely on online reviews, a prominent form of electronic word-of-mouth (eWOM), before making a purchase decision. However, consumers are usually confronted with hundreds of reviews for a single product or service, as well as rich information cues on online review websites (review texts, helpfulness ratings, author information, etc.). In turn, consumers face more information cues on online review websites than they can or want to process, and are likely to proceed selectively. This paper investigates selective processing of such eWOM information cues. Results of Study 1, an exploratory study using verbal protocols, confirm that consumers display selective eWOM processing patterns and are able to articulate them. Study 2 develops and applies a measurement instrument to capture these patterns. A subsequent cluster analysis on members of a large-scale online panel (N = 2,295) indicates five prominent eWOM processing types, termed “The Efficients”, “The Meticulous”, “The Quality-Evaluators”, “The Cautious Critics”, and “The Swift Pessimists”. Insights of this research can help firms to better understand consumers' eWOM processing and improve the user-friendliness of online review websites.     

Understanding the role of social influence in piquing curiosity and influencing attitudes and behaviors in a social network environment

Social networks provide an innovative means for facilitating social influence as well as arousing consumer curiosity. However, research on how social influence impacts attitudes and behaviors in this context is limited. Further, even less research exists examining how curiosity impacts consumers’ behaviors, which is concerning since curiosity may be especially relevant in an online setting. To overcome these gaps, two studies were conducted which demonstrate that a consumer's curiosity toward a social network post is influenced by the group membership of the individual who created the post. In turn, curiosity leads to more positive attitudes toward the experience described or represented in the post, which leads to higher intentions to undertake that experience. Additionally, consumer susceptibility to interpersonal influence is found to moderate the relationship between group membership and curiosity. If susceptibility to interpersonal influence is strong enough, content posted by a dissociative group member can also arouse curiosity and positively influence attitudes and behavioral intentions.     

Information direction, website reputation and eWOM effect: A moderating role of product type

This article examines how the electronic word of mouth (eWOM) information direction (positive vs. negative) and a website's reputation (established vs. unestablished) contribute to the eWOM effect. The article describes a study focusing on the moderating role of the product type (search vs. experience). The results of the experiment show that the eWOM effect is greater for negative eWOM than for positive eWOM, greater for established websites than for unestablished websites, and greater for experience goods than for search goods. The results support the moderating effects of product type on the eWOM information direction-website reputation-eWOM effect relationship. The impact of negative eWOM on the eWOM effect is greater for experience goods than for search goods. Similarly, the impact of website reputation on the eWOM effect is greater for experience goods than for search goods. The findings provide managerial implications for an Internet marketing strategy.     

When does electronic word-of-mouth matter? A study of consumer product reviews

Online consumer product reviews, a form of electronic word-of-mouth (eWOM), have attracted increased attention from researchers. This paper examines the persuasiveness of eWOM. Drawing on regulatory focus theory, the authors propose that the consumption goals that consumers associate with the reviewed product moderate the effect of review valence on persuasiveness. Data from lab experiments and actual online retailers suggest that consumers who evaluate products associated with promotion consumption goals perceive positive reviews to be more persuasive than negative ones (i.e., a positivity bias). Conversely, consumers who evaluate products associated with prevention consumption goals perceive negative reviews to be more persuasive than positive ones (i.e., a negativity bias).     

Memorable customer experiences and autobiographical memories: From service experience to word of mouth

The aim of this paper is to study the relationship between customer experience and word of mouth (WOM) through two mediating variables: customer satisfaction and memorable characteristics of service experience (MCSE). Memory theory is adopted as a theoretical background, with emphasis on the key role of episodic or autobiographical memory. Memorable customer experience (MCE) is defined from this perspective, thereby enabling the connection between human memory theory and service-dominant (S-D) logic. As for the impact of the internet on WOM, two types of WOM behaviours are examined: positive WOM (pWOM) and eWOM. A methodology was designed from a survey that used a questionnaire based on measurement scales validated by the literature. The sample is of 1476 tourists who visited seven Spanish tourism destinations. The results show service experience precedes customer satisfaction and MCSE. Both pWOM and eWOM are significantly influenced by customer satisfaction and MCSE. Various scenarios are put forward in which several combinations of customer satisfaction and MCSE give rise to different intensities and valence of pWOM and eWOM.     

Interrupted anticipation after a service failure: The role of olfactory sensation on expected pleasure, taste enjoyment, consumption, and repatronage intentions

When consumers are highly charged with the anticipation of indulging in a pleasurable eating experience, a service failure that threatens to deny them the opportunity to satisfy their appetitive goals produces an “interrupted anticipation.” This study demonstrated that among those whose eager anticipation was interrupted by an unexpected service failure, food aroma tended to reinforce unpleasant feelings and generally negate the positive emotional boost normally expected from a positive olfactory cue. This resulted in significantly lower levels of expected pleasure, taste enjoyment, quantity of food consumed, and repatronage intentions. In contrast, for those whose anticipation was not interrupted, the food aroma exposure significantly enhanced the positivity of the consumer's service experience. When service failures lead to interrupted anticipation, service recovery efforts may sometimes prove to be ineffective in restoring the positive feelings of customers. Implications for theory development and managerial practice are also discussed.     

Are Low Price and Price Matching Guarantees Equivalent? The Effects of Different Price Guarantees on Consumers’ Evaluations

Some retailers offer price match guarantees, whereas others offer guarantees making the same promise but labeling these low-price guarantees. Do consumers respond differently to these different price guarantee labels? To address this research question, this paper leverages insights from pricing, signaling, and regulatory focus theories to demonstrate – across multiple studies – that consumers perceive price match versus low price guarantees differently. In turn, contingent on consumers’ regulatory focus, this difference in perceptions feeds forward and influences consumers’ purchase intentions and post purchase (e.g., repurchase) intentions. This paper contributes to theory, not only by showing differences across price match versus low price guarantees, but also by being the first to jointly examine purchase and post purchase intentions relating to price guarantees. This paper also speaks to practice, noting contingencies that determine whether the price match or the low-price guarantee label should be used.     

The relationship between Internet addiction and negative eWOM

Customers prevalently use social media (SM) to post their experiences and to review others’ experiences. This study investigated how Internet addiction (IA) influenced customers’ word-of-mouth behaviors on SM after a service failure, focusing on both young and older customers. Two experiments were conducted. The first study was conducted with young customers and second experiment with older customers. Results suggest that the group of young customers had significantly higher levels of IA, compared to older customers. The analysis identified that IA and functional/technical service failure partially influenced four negative types of electronic word-of-mouth (eWOM) (i.e. Badmouthing, Tattling, Spite, and Feeding the Vultures). Both young and older customers tended to show more negative eWOM types for technical service failures. For the functional service failures, IA was the main predictor of negative eWOM for both young and older customers.     

Product standardisation in the food service industry: post-purchase attitudes and repurchase intentions of non-Muslims after consuming halal food

In order to satisfy the Muslim market segment, many restaurant and fast food companies in Western countries have standardised their products by switching to halal. The purpose of this research is to discover the extent to which non-Muslim consumers in non-Muslim countries experience cognitive dissonance when they think about restaurants and fast food outlets having likely served them halal-produced food, and the extent to which these consumers intend to repurchase halal food. Data came from a total sample of 1097 non-Muslim consumers in Canada, Spain and the United Kingdom. The full model, with religious identity, ethnic identification and interest in animal welfare as antecedents of cognitive dissonance, explained 35% of the variance in consumers’ repurchase intentions. Our findings suggest that many non-Muslims do not have a particular issue with consuming halal food, but they may react negatively if they unintentionally consume halal food and perceive that they have been deprived of information, or worse still, deliberately deceived. The research makes a number of contributions to marketing knowledge with regard to the negative spillover effects that can result from faith-based product standardisation, and the influences of consumer interest in animal welfare and deprivation of product information on consumer behaviour.     

Determinants of consumers’ purchase behaviour towards green brands

This study applies perceived risk theory to explore the factors that influence consumers’ purchase behaviour towards green brands, including green perceived quality, green perceived value, green perceived risk, information costs saved, and purchase intentions towards green brands. This study focuses on consumers who have the experience of purchasing products from green brands in the food and restaurant service industry in Taiwan. The results of this study show that purchase intentions are positively associated with purchase behaviour. Moreover, the study demonstrates that purchase intentions mediate the impacts of green perceived quality, green perceived value, information costs saved, and green perceived risk on purchase behaviour. Specifically, green perceived risk is negatively influenced by green perceived value and information costs saved and functions as a mediator among green perceived value, information costs saved, and purchase intentions. The study has critical implications for green brand researchers and practitioners.     

The Influence of Bundling and Caloric Knowledge on Calories Ordered and Purchase Intent

This article investigates the impact of a bundle promotion on calories ordered and purchase intentions toward bundles in a fast food context. The results of our study show that consumers order more calories and have higher purchase intentions toward bundles when a bundle promotion is advertised than when it is not, particularly for consumers with low caloric knowledge. Moreover, the results suggest that the underlying mechanism influencing these results is consumers' perceptions that a bundle is considered an appropriate option among consumers.     

Trust in online recommendations: an evolutionary psychology perspective

Electronic word-of-mouth (eWOM) is playing an increasingly important role in influencing consumer behavior, and it represents another opportunity for marketers to build support for their brands. This study explores how the gender of the reader influences how eWOM is perceived. An experiment grounded in evolutionary psychology examines how males and females differ in their perceived trust of eWOM of positive, negative, or mixed valence. The results indicate that females place greater trust than males in eWOM messages. But both genders find eWOM of mixed valence more trustworthy than entirely positive or negative eWOM. A follow-up phenomenological study of male and female consumers who had experienced eWOM shed more light on the experimental findings and offers additional support for their evolutionary basis. Theoretical and practical implications are discussed as well as recommendations for further research.     

Understanding consumers’ multichannel choices across the different stages of the buying process

This article provides a more integrative approach toward channel choice than previous research by considering all stages of the buying process (search, purchase, and after-sales), and by taking channel attributes, experience, and spillover effects into account when examining consumers?? channel choice intentions. The authors show that such an integrative perspective is important as channel attributes, experience, and spillover matter for consumers?? channel choices in all stages of the buying process. Notably, the study stresses the importance of channel experience and spillover effects for explaining consumers?? channel choice intentions in the different stages of the buying process. Channel experience effects occur when using the channel increases the likelihood that the consumer will use the very same channel on the next occasion. Spillover effects result when the likelihood of using a channel in one stage of the buying process affects the likelihood of choosing that channel in another stage. The results show that both effects influence consumers?? channel choice intentions over and above channel attributes. Importantly, the model results strongly pledge for studying attribute, experience, and spillover effects simultaneously.     

How Dispersive Opinions Affect Consumer Decisions: Endowment Effect Guides Attributional Inferences

Electronic word-of-mouth (eWOM) dispersion, reflecting the extent of reviewers’ opinion divergence regarding a product, determines consumer decisions. Drawing upon the endowment effect and attribution literature, this research proposes that the endowment effect mediates the influence of eWOM dispersion on attributional inferences, and the display formats of eWOM dispersion (“horizontal bar chart” vs. “eWOM content”) moderate the mediating influence of endowment effect on attributional inferences of eWOM dispersion. Three complementary studies reveal three key insights in this setting. First, when consumers already having an emotional attachment to a product and subsequently encountering dispersive eWOM, the higher the level of eWOM dispersion, the stronger the endowment effect. Secondly, In such circumstance, the stronger endowment effect promotes more reviewer-related attribution inference of high-dispersion eWOM, and the weaker endowment effect promotes more product-related attribution inference of low-dispersion eWOM. Third, the positive influence of eWOM dispersion on endowment effect is stronger for eWOM dispersion in the complexity or disfluency display format (i.e. “reviewers’ impression of product”) than for eWOM dispersion in the simply of fluency display format (i.e. “horizontal bar chart”), more importantly, the mediating influence of endowment effect on attributional inferences is moderated by the display formats of eWOM dispersion, and this findings persists even when product category (hedonic vs. utilitarian) is taken into consideration. The theoretical implications for the eWOM dispersion and attribution literature and practical implications for online retailers are discussed.     

Addressing the Texting and Driving Epidemic: Mortality Salience Priming Effects on Attitudes and Behavioral Intentions

Texting while driving is becoming a problem of epidemic proportion, causing thousands of fatalities each year. However, surprisingly few academic studies to date have examined this issue in a social marketing context. We address this research void by reporting the findings of two empirical studies—the first, an exploratory study of drivers' perceptions of texting while driving; the second, an experimental examination of the relative effectiveness of mortality salience (MS) primes in public service announcements (PSAs). Employing theory derived from the MS literature, we find that when verbal and/or visual cues to death/dying were used, participants' attitudes and behavioral intentions were altered in a positive direction. As compared to a control group, the primed PSAs produced less favorable attitudes and reduced intentions to text while driving in the future. Implications of these findings for consumers, social marketers, and policymakers are discussed, and future research directions are provided.
