Mechanisms of consumers' trust development in reviewers' supplementary reviews: A reviewer-reader similarity perspective

The literature on online reviews tends to focus on initial consumer postings and reviews, but supplementary online reviews posted by the same reviewer remain an unexplored area in marketing in general and hospitality in particular. To address this gap in the research, this study offers a research model that examines the effects of reviewers' attributes on consumer trust and positive behavioral outcomes, using hotel attributes performance as a moderator. Using responses from 414 hospitality consumers in China, our findings reveal that reviewers whose supplementary reviews use similar identities to those of their initial review, review similar firms, and use similar websites gain consumers' trust. Hotel attributes performance has a strong positive moderating effect on the relationship between reviewers' attributes and consumers' trust, and the trust engendered in this way creates the psychological comfort that leads to positive behavioral outcomes. Implications for theory and practice are discussed along with suggestions for future research.     

The impact of online reviews on hotel booking intentions and perception of trust

A growing reliance on the Internet as an information source when making choices about tourism products raises the need for more research into electronic word of mouth. Within a hotel context, this study explores the role of four key factors that influence perceptions of trust and consumer choice. An experimental design is used to investigate four independent variables: the target of the review (core or interpersonal); overall valence of a set of reviews (positive or negative); framing of reviews (what comes first: negative or positive information); and whether or not a consumer generated numerical rating is provided together with the written text. Consumers seem to be more influenced by early negative information, especially when the overall set of reviews is negative. However, positively framed information together with numerical rating details increases both booking intentions and consumer trust. The results suggest that consumers tend to rely on easy-to-process information, when evaluating a hotel based upon reviews. Higher levels of trust are also evident when a positively framed set of reviews focused on interpersonal service.     

The influence of trust perceptions on German tourists’ intention to book a sustainable hotel: a new approach to analysing marketing information

ABSTRACT

This study examined the relationship between German tourists’ trust perceptions and their intention to book a sustainable hotel, pioneering a new quantitative approach to sustainable tourism marketing. Data came from 300 respondents who participated in an online survey. Respondents were given a digital brochure to read containing information about a “fictitious” three-star beach hotel in Portugal, before completing a questionnaire that measured inter alia their intention to book this sustainable hotel. Both individual “general trust” (perception of others’ trustworthiness) and “specific trust” towards the fictitious hotel in the brochure were measured. The survey also evaluated respondents’ perceptions about the usefulness of the information in the brochure. Multiple regression analysis of the data indicated that general trust, trusting the hotel and perceived usefulness of the brochure were positively and significantly related to booking intentions. An interaction between general trust and perceived usefulness was also observed. This means that the higher the perception rate about the brochure's usefulness, the higher general trust was for booking intentions and vice versa. The practical implications of the results suggest that tourists could be motivated to book a hotel if its sustainability attributes and amenities were communicated in a trust inspiring way in marketing material.     

The effect of online reviews on hotel booking intention: The role of reader-reviewer similarity

Due to the experiential nature of travel-related products, online reviews have become an increasingly popular information source in travel planning and have a profound effect on consumers’ buying decisions, particularly in hotel booking. On the basis of homophily and similarity-attraction theory, we posit that review valence is positively related to consumers’ hotel booking intentions, and expect this relationship to be moderated by surface- (demographic) and deep-level (preference) similarities. The findings from two experiments conducted in Germany and Macau indicate that review valence significantly affects hotel booking intention, and that reader-reviewer demographic similarity moderates this effect. This three-way interaction reveals a substituting moderation effect between demographic similarity and preference similarity. One practical implication is that travel websites should find methods of exposing users to reviews written by those with either similar demographic characteristics or preferences, which facilitate travelers’ decision-making processes.     

Which reviewers are honest and caring? The effect of constructive and prosocial information on the perceived credibility of online reviews

Consumers often infer review credibility based on the content of online reviews. This study explores the influences of three positive review types on consumers’ perceptions of posters’ honesty and caring and subsequently review credibility. An experiment was conducted and the participants included 931 online travel community users. The results found that compared with positive reviews that contain only complimentary information, reviews that also contain constructive or prosocial information improve subjects’ perception of posters’ honesty and caring, respectively, and that this influence is particularly significant for participants with low propensity to trust. Second, compared with hotels with high reputation, consumers have significantly reduced perceptions of reviewers’ honesty if the reviewers provide only complimentary information in positive reviews for hotels with low brand reputation rather than both complimentary and constructive information. Finally, the higher the subjects’ perception of the reviewers’ honesty and caring is, the higher the consumers’ perception of review credibility.     

Consumers’ responses to ambivalent online hotel reviews: The role of perceived source credibility and pre-decisional disposition

Electronic word-of-mouth (eWOM) is prevalent in today's lodging market and has potential to influence consumers’ decision making. This study investigated how the presence of online reviewers’ personal identifying information (PII) may affect consumers’ processing of ambivalent online hotel reviews and hotel booking intentions. The results of an experiment with a sample of 274 undergraduate students indicate that the presence of PII positively affects the perceived credibility of the online reviews. When coupled with ambivalent online reviews, the presence of PII significantly lowers consumers’ hotel booking intentions.     

Do consumers care about CSR in their online reviews? An empirical analysis

This research investigates how consumers assess hotels’ corporate social responsibility (CSR) practices when writing online reviews. The study explores the CSR discourse in online reviews over a 10-year period, highlighting how CSR’s social and environmental dimensions relate to the main hospitality topics (experience, amenities, location, transactions, value). Based on a longitudinal automated text analysis covering 480,000 reviews across six European cities, the findings reveal that hotel customers have gradually begun paying more attention to CSR factors, particularly to social and environmental ones. However, the aggregate results suggest that the overall CSR consumer discourse is still very limited, although it does have important implications in terms of consumer emotions and hospitality dimensions.     

Helpful Reviewers in TripAdvisor,an Online Travel Community

Online communities need a critical mass for communication, information, and entertainment and should provide useful information for their members in order to obtain this critical mass. The abundance of online travel reviews increases cognitive costs of travelers, and travelers use extrinsic cues to judge the quality of online reviews to eliminate costs associated with the information process. Of various cues used in online environments, this study examined an online reputation system in TripAdvisor.com and profiled the reviewers who post helpful reviews in the online travel community. The key findings include that helpful reviewers are those who travel more, actively post reviews, belong to any age and gender groups, and give lower hotel ratings. This study adds to research of online travel reviewers by characterizing helpful information creators among online content creators.     

The impact of language style on consumers′ reactions to online reviews

The current research examines the novel impact of an online review's language style (figurative vs. literal) on consumers' attitudes towards a hotel and their reservation intention. Previous marketing research advocated for the use of figurative language to advertise hedonic consumptions. Yet, we found that, in the context of online hotel reviews, figurative language doesn't offer significant advantages in terms of persuasive power. Specifically, our findings indicate that, when a review is posted by a reviewer with low expertise level, consumers actually exhibit lower levels of attitude and reservation intention if the review is written in figurative (vs. literal) language. When the reviewer possesses high expertise level, the language style effect was attenuated. Finally, serial mediation tests show that the causal link between language typicality → perceived reviewer expertise explains the language style effect on consumers' pre-purchase evaluations.

Analysis of the perceived value of online tourism reviews: Influence of readability and reviewer characteristics

Online reviews provide additional product information to reduce uncertainty. Hence, consumers often rely on online reviews to form purchase decisions. However, an explosion of online reviews brings the problem of information overload to individuals. Identifying reviews containing valuable information from large numbers of reviews becomes increasingly important to both consumers and companies, especially for experience products, such as attractions. Several online review platforms provide a function for readers to rate a review as “helpful” when it contains valuable information. Different from consumers, companies want to detect potential valuable reviews before they are rated to avoid or promote their negative or positive influence, respectively. Using online attraction review data retrieved from TripAdvisor, we conduct a two-level empirical analysis to explore factors that affect the value of reviews. We introduc a negative binomial regression model at a review level to explore the effects of the actual reviews. Subsequently, we apply a Tobit regression model at the reviewer level to investigate the effects of reviewer characteristics inferred from properties of historical rating distribution. The empirical analysis results indicate that both text readability and reviewer characteristics affect the perceived value of reviews. These findings have direct implications for attraction managers in their improved identification of potential valuable reviews.     

Online reviews and purchase intention: A cosmopolitanism perspective

In recent years, marketing managers have realized that online reviews are an essential element in customer decision-making. However, there has been little valid measure of online reviews and no systematic analysis of their effect on consumer purchase intention. Drawing on the uses and gratification (U&G) and consumer culture (CCT) theories, this study develops a valid measure of online reviews and analyzes their effect on purchase intention. With a sample of 1112 hotel customers from three countries (Taiwan, Thailand, and Vietnam), this study validates the positive effect of online reviews on purchase intention through the perceived effectiveness of social media platforms (PESMP) and online trust while confirming the moderating role of cosmopolitanism.     

Free add-on services and perceived value in competitive environments: Evidence from online hotel reviews

This study investigates how free add-on services affect customers’ perceived value in horizontal and vertical competition. We collected 349,879 reviews about over 3000 hotels in 25 U.S. cities from TripAdvisor. Using three balanced data sets generated by coarsened exact matching, the ordered logistic regressions show that free hotel add-on services (including free breakfast, parking, and WiFi) positively affect consumers’ perceived value. However, increased horizontal and vertical competition differentially weakens the positive effects of free add-on services. We not only observe a negative moderating effect of horizontal competition, but also identify three patterns of the marginal effects of these three add-ons in horizontal competition. The moderating effect of vertical competition exists from the higher-grade hotel segment to a lower-grade hotel, but such an effect is insignificant from the lower-grade hotel segment to a higher-grade hotel. Therefore, hotel managers should consider diverse external competitive environments and design appropriate differentiated service strategies.     

Joint effects of management responses and online reviews on hotel financial performance: A data-analytics approach

Hotels are increasingly shifting their online review strategy from passive listening to proactive engagement through management responses. This study investigates the joint effects of management responses and online reviews on hotel financial performance. Based on a large unique dataset of 22,483 management responses to 76,649 online consumer reviews on TripAdvisor over 26 quarters, matched with quarterly hotel financial performance, this study finds that providing timely and lengthy responses enhances future financial performance, whereas providing responses by hotel executives and responses that simply repeat topics in the online review lowers future financial performance. Moreover, review rating and review volume moderate the effects of management responses. When the average review ratings increase, more management responses of greater length should be provided. As review volume grows, the benefits of providing timely and lengthy responses diminish. The study findings generate new implications for managing responses to online reviews to increase hotel financial performance.     

A critical review of determinants of information search behavior and utilization of online reviews in decision making process (invited paper for ‘luminaries’ special issue of International Journal of Hospitality Management)

This conceptual paper provides a brief review of hospitality consumers’ information search behavior and the factors that are likely to influence their information search behavior and their utilization and processing of online reviews. This study focuses on the factors such as information overload, confusion, information processing, information presentation format, trust and evaluation mode that has not received much attention from hospitality scholars in addition to discussing the impacts of perceived risk and familiarity on information search and information processing approaches utilized by hospitality consumers. This study also discusses opportunities for hospitality researchers to empirically examine the extent to which each of the factors discussed might influence hospitality consumers information search, information processing and especially their utilization of online reviews in their decision making process.     

Sustainability Management of Hotels: How Do Customers Respond in Online Reviews?

The purpose of this study was to investigate how guests respond to the sustainability efforts of sustainably managed hotels by discussing them in reviews posted online. Thus, an exploratory research design and the content analysis method were chosen for this study. The content analysis technique was used to analyze User Generated Content and to explore what attributes of sustainability are perceived as the most important by hotel guests in online reviews and whether they generate positive or negative feelings. An analysis of the reviews showed that hotel guests perceive sustainability positively: most indicators were discussed in a positive context, and reviews that contained sustainability attributes had higher guest ratings than other reviews. Explicit references to sustainability were found in only 6.8% of all customer comments. The most frequently encountered indicators in guest reviews were biodiversity, education and sustainable products. Customers mainly discuss attributes that have direct impacts on their experience or are observable at the hotel. Customers are likely to realize that a hotel’s commitment to sustainability can excuse the hotel for a suffered inconvenience. This finding implies that hoteliers should educate guests on their sustainability measures, as higher awareness may increase customer satisfaction.     

What moderates the influence of extremely negative ratings? The role of review and reviewer characteristics

Online customer reviews are increasingly used by travelers to inform their purchase decisions. However, the vast amount of reviews available nowadays may increase travellers’ effort in information processing. In order to facilitate traveller’s decisions, social commerce organizations must help travellers rapidly identify the most helpful reviews to reduce their cognitive effort. Academic literature has often documented that negative reviews are judged as helpful by consumers. However, extremely negative reviews are not always perceived as such. This study is the first that unveils what factors moderate the influence of extremely negative reviews on review helpfulness. The study has adopted a sample of 7455 online customer reviews of hotels to test hypotheses. Findings show that reviews with extremely negative ratings are more likely to be helpful when the review is long and easy to read and when the reviewer is an expert or discloses his identity (i.e. geographical origin).     

Booking now or later: Do online peer reviews matter?

Consumers always face a tradeoff between making a purchase decision now and continuing information searching with delayed purchase decision. This study extends extant literature by empirically investigating the effects of online peer reviews on consumers’ timing of booking a restaurant using a merged data set of online peer reviews and consumer reservation records. The results show that the rating valence, rating variation, and review content richness of online peer reviews positively motivate potential consumers to book a restaurant earlier, while the time interval between successive reviews hinders consumers’ booking decision. It is also found that the effects of rating valence on timing of restaurant booking depend on the different levels of rating variation and review content richness. The findings of this study help practitioners better understand consumers’ purchase decision process and improve marketing strategies.     

Online persuasion of review emotional intensity: A text mining analysis of restaurant reviews

Consumer-generated restaurant reviews are important sources in consumers’ purchase decisions. The purpose of this study is to explore the impact of emotional intensity on perceived review usefulness as well as the moderating effects of review length and reviewer expertise. Data from 600,686 reviews of 300 popular restaurants in the US were obtained from Yelp. Using a text mining approach and econometric analysis, empirical results show that (1) positive emotional intensity has a negative impact on perceived review usefulness, whereas negative emotional intensity has a positive impact on perceived review usefulness; (2) among the two most prevalent discrete negative emotions in online reviews (i.e., anger and anxiety), reviews expressing anger are more useful than those expressing anxiety; and (3) review length and reviewer expertise can moderate the effect of emotional intensity on perceived review usefulness.     

Responding to negative online reviews: The effects of hotel responses on customer inferences of trust and concern

Our research examines the perceptions and evaluations of prospective customers toward an online negative review and any accompanying hotel response. The study explores two main issues: whether the presence (versus absence) of an organizational response to negative customer reviews affects the inferences potential consumers draw about the target business, and which aspects of responses affect their impressions. We test the effects of four variables associated with a response: source of response, voice of responder, speed of response, and action frame on two outcomes variables (i.e., customer concern and trust inferences). The provision of an online response (versus no response) enhanced inferences that potential consumers draw regarding the business's trustworthiness and the extent to which it cares about its customers. Using a human voice and a timely response yielded favorable customer inferences. Inferences did not vary with response source or action frame. Implications are drawn for effective management of negative online reviews.
