Effects of human versus virtual human influencers on the appearance anxiety of social media users

The association between social media use and an individual's appearance dissatisfaction has generated broad scholarly interests. This study explored the specific appearance dissatisfaction resulting from the effects of social media influencer images on the appearance anxiety of users, in particular the differences between human influencers (HIs) and emerging virtual influencers (VIs). Women (n = 178) aged 18–35 were randomly assigned to HI images, VI images, and scenic images (control group) and were asked to answer related questionnaires. The results showed that images of both HI and VI induced significantly higher appearance anxiety than in the control group. The participants who were exposed to VI images reported significantly lower appearance anxiety than those who were exposed to HI images. Participants' state appearance comparison played a mediating role between the images of social media influencers and appearance anxiety. In addition, participants who viewed VI images reported significantly lower state appearance comparison than those who viewed HI images. Insights for influencer marketing practice were further discussed based on the results.     

Influencer marketing: When and why gen Z consumers avoid influencers and endorsed brands

Consumer avoidance of brands and influencers is a widespread phenomenon, especially among Generation Z (Gen Z); however, influencer marketing literature lacks clarity about when and why Gen Z engages in such avoidance. Our experimental investigation, across four studies, reveals that Gen Z considers brands' control over influencers to be morally irresponsible and, thus, avoids both. We introduce a novel construct, influencer avoidance, and examine its drivers. Study 1 indicates that perceived brand control engenders avoidance; moderation evidence shows that macro (vs. micro) influencers accentuate (attenuate) the influence of brand control on avoidance. Study 2 shows that Gen Z enjoying a strong versus weak relationship with influencers results in lower (higher) avoidance towards influencers and endorsed brands. Study 3 demonstrates that negative moral emotions mediate the relationship between perceived brand control and avoidance behavior. Study 4 generalizes the findings by analyzing a different influencer and endorsed brand and including a prominent advertisement disclosure. By investigating the drivers and mechanisms of Gen Z's avoidance behavior, our research contributes to research on the theory of moral responsibility, Gen Z's influencer avoidance behavior, and anti-consumption literature. This offers key insights into how to prevent acts of consumer retribution towards influencers and brands.     

Marketing through Instagram influencers: the impact of number of followers and product divergence on brand attitude

ABSTRACT

Findings of two experimental studies show that Instagram influencers with high numbers of followers are found more likeable, partly because they are considered more popular. Important, only in limited cases, perceptions of popularity induced by the influencer's number of followers increase the influencer's perceived opinion leadership. However, if the influencer follows very few accounts him-/herself, this can negatively impact popular influencers’ likeability. Also, cooperating with influencers with high numbers of followers might not be the best marketing choice for promoting divergent products, as this decreases the brand's perceived uniqueness and consequently brand attitudes.     

The effects of influencer type,regulatory focus,and perceived authenticity on consumers' purchase intention

Companies often use influencers to promote their products, and many celebrities have expanded their activities on social media as influencers. In this work, we classified influencers into celebrity and noncelebrity groups and analyzed how they affect consumers' purchase intention. We also analyzed how psychological variables, such as regulatory focus and perceived authenticity affect this process. We conducted three studies with consumers in China, South Korea, and the United States who participated in each between-subjects experiment. The results showed that people have higher purchase intention for products recommended by noncelebrity influencers than those recommended by celebrity influencers. We also found that regulatory focus moderates the relationship between the influencer type and consumers' purchase intention. Purchase intention for products recommended by noncelebrity influencers were stronger among prevention-focused consumers. However, no significant difference in the effect of influencer type was found among promotion-focused consumers. We found that perceived authenticity mediated this moderating effect. The results of this study provide effective marketing strategies and implications for companies when they use influencers as a tool for marketing activities.     

Trust me,I'm an influencer! - Causal recipes for customer trust in artificial intelligence influencers in the retail industry

Prior examinations of relationship development and the leverage of trust among artificial intelligence (AI) influencers and followers have been few. This study employed complexity theory to understand the main causal recipes that can lead to high trust in AI influencers. Asymmetrical fuzzy set qualitative comparative analysis (fsQCA) was used to explore the recipes that can drive high customer trust. Data were collected from 683 consumers who are familiar with AI influencers in Saudi Arabia. Our findings indicated that no single factor is sufficient to drive trust in influencers, but five causal recipes were explored for their power to secure high levels of trust in AI influencers. The findings revealed that a configuration of source attractiveness (i.e., physical attractiveness, homophily), source credibility (i.e., authenticity, expertise) and congruences (i.e., influencer, product, consumer) act as driver of consumers' trust in an AI influencer. These results are useful for practitioners since they provide new methods for boosting trust in AI influencers.     

Can you sense without being human? Comparing virtual and human influencers endorsement effectiveness

As AI increasingly permeates digital spaces, virtual influencers are operating in similar ways as human influencers. However, given their recent introduction, the effectiveness of virtual influencers is unclear, and there is limited managerial guidance regarding when and how they should be used. Across four studies, including an empirical investigation using secondary data analysis and three scenario-based experiments spanning two cultural contexts, we find that virtual influencers are less effective than human influencers as endorsers in terms of brand attitude and purchase intention. Furthermore, we identify perceived sensory capability and credibility as the serial mechanism. Lastly, we introduce the salience of sensory cues within the ad as a theoretically important and managerially relevant moderator, which attenuates the negative effect of virtual influencers. This research extends virtual influencer literature by focusing on business-related outcomes. Our theoretical model highlights essential differences in advertising outcomes between human and virtual influencers and provides important managerial implications.     

Social media influencers and consumer engagement: A review and future research agenda

The rise of social media influencers (SMIs) in the recent decade garnered wide interest from academicians and marketers. Academicians try to understand the effect of influencers on consumer behaviour, while marketers use influencers as part of their strategy to achieve marketing objectives. Although, plenty of practical and conceptual research is available in this area, literature reviews in the domain of SMIs and consumer engagement are scarce as it is still developing, and most of the studies have focused on these two concepts separately. In this study, the authors attempted to combine and understand how social media influencers affect consumers engagement. This systematic review of the literature offers a comprehensive view of previous research on social media influencers and consumer engagement. The study reviewed articles published in the Australian Business Deans Council (ABDC), Scopus, and Web of Science indexed journals till 5 June 2021. To understand consumers' engagement with SMIs, authors identified and theorized the antecedents, decision and outcome of such engagement. It also discusses the influencer-follower parasocial relationship on different social media platforms. The study proposes an integrated conceptual framework that can be further used to test and validate the impact of social media influencer's marketing efforts on consumer engagement. This framework also may serve as a foundation for marketers to develop effective influencer strategies for brand promotions. The review concludes the discussion by highlighting theories, methodology, and context of studies conducted by past researchers.     

Antecedents and outcomes of digital influencer endorsement: An exploratory study

The advertising and marketing literature have established that celebrity endorsements constitute an effective way to enhance attitudes toward brands and increase purchase intents. However, there are no relevant studies on digital influencers. This study addresses the research gap by examining the effect of digital influencers' attractiveness and the effect of the congruence between a digital influencer and a brand on consumer attitudes and purchase intentions. By applying structural equation modeling to a sample of 307 followers of digital influencers, a model was tested and group analysis was performed for two categories (“entertainment & video games” and “fashion & beauty”). The results show that both brand attitudes and purchase intentions are influenced by the digital influencer's attractiveness (which includes both likeability and familiarity) and by the congruence between the digital influencer and the brand. This study makes several contributions to both theory and practice, which are highlighted in this paper.     

Social media influencers: The formation and effects of affective factors during online interactions

Social media influencers emerged as powerful sources in affecting and guiding consumers' purchase decisions through self-generated content and online interactions with their followers. A large number of studies have so far focused on cognitive aspects such as perceived credibility, trustworthiness, and expertise of these influencers. This study aims to further advance the existing literature on social media influencer marketing from an affective perspective, with a focus on the emotional bonds generated by online interactions between the influencer and their followers. Based on the interpersonal process model of intimacy and theories in celebrity endorsement and social media influencer marketing, it examines the impact of self-disclosure and perceived responsiveness on familiarity and intimacy, which, in turn, affect purchase decision. An online survey was conducted with 304 social media users in Mainland China who have followed social media influencers. The results highlight the formation of two affective factors, namely, familiarity and intimacy, via self-disclosure and perceived responsiveness. Theoretically, this study provides a fresh perspective to better understand the endorser effect outside the regular set of cognitive factors. Marketing practitioners and companies can follow the suggestions of this study to select more effective social media influencers for their marketing campaign, and to build closer relationships with their target customers.     

Stereotyping human-like virtual influencers in retailing: Does warmth prevail over competence?

Building upon the Stereotype Content Model (SCM), the current research provides insights into how virtual influencers (VIs) influence consumer responses. More specifically, it investigates the associations between the VI's anthropomorphism and stereotypical judgments of the VI's warmth and competence as well as the differential and mediating roles of these stereotypes in influencing consumers' willingness to follow the VI's recommendations and purchase intentions. The results support the idea that anthropomorphizing VIs has a direct bearing on stereotyping VIs along the competence and warmth dimensions of the SCM. Consistent with the “Primacy-of-Warmth Effect” hypothesis, the study's findings show that perceived warmth, compared to perceived competence, is positively more associated with consumers' willingness to follow the VI's recommendations. Furthermore, the findings reveal that perceived warmth mediates the association between the VI's anthropomorphism and consumers' willingness to follow the VI's recommendations. However, the findings lend partial support to the mediating role of competence. The willingness to follow the VI's recommendations, in turn, is positively associated with purchase intention. The paper wraps up with some implications for research and practice.     

How,why, and when disclosure type matters for influencer marketing

Consumers’ changing media consumption behaviors and skepticism toward traditional forms of advertising have prompted the growth of influencer marketing. Even as regulatory authorities call on brands and influencers to disclose the posts as advertising, no consistent guidelines exist. The distinct effects of self-generated versus platform-initiated disclosures also remain unclear, nor has research addressed the interplay of key influencer characteristics and marketing disclosures. This article reports on findings from the first academic field study of influencer marketing disclosures, as well as three experimental studies, which indicate that disclosure is a double-edged sword. When provided through a platform-initiated branded content tool, disclosure consistently exerts the strongest effect on perceptions of advertising, negatively relating to influencer trustworthiness and consumer engagement. The effects of disclosure type also depend on the number of followers and number of previously endorsed products (i.e., influencer characteristics). Yet, consumers also express appreciation for transparency when influencers disclose posts as advertising, which increases perceived trustworthiness of the influencer and engagement with the post. The implications of these findings should inform choices by public policy makers, brand managers, and influencers.     

Building influencers' credibility on Instagram: Effects on followers’ attitudes and behavioral responses toward the influencer

Collaborations between influencers and brands have become increasingly popular in recent years. Previous research has mainly focused on influencer marketing as a commercial action designed to enhance followers' perceptions and reactions toward promoted brands, ignoring the consequences of these promotional actions on influencers' credibility and their relationships with their followers. This research sheds light on the topic by exploring how influencers' promotional actions affect their credibility, and followers' attitudes and behavioral responses toward the influencer (i.e., to continue following, imitate, and recommend them to other users). A study addressed to the followers of a popular influencer was carried out to test the research model. The results showed that perceived influencer-product congruence positively affects followers' perceptions of the credibility of, and attitude toward, influencers, and negatively affects perceptions of paid communication. Followers' perceptions that influencers have been paid to take part in promotional activities harms their credibility; however, credibility is essential for generating positive attitudes toward the influencer. Finally, both perceived credibility and attitude foster positive behavioral responses toward the influencer; influencers must enhance these factors to retain their influencing capacity. This research provides managerial implications for influencers and brands that can help enhance followers’ experiences when exposed to promotions on social media.     

Effective influencer marketing: A social identity perspective

Social networking in the form of online communities and social groups is a characteristic of social media communication that has profound implications on the identity dynamics and behavior of social media users. Drawing from social identity theory, this research brings the social identity construct (i.e., followers' perception of the self in relation to the influencer community) to the literature on influencer marketing and examines the effect of followers' social identity, along with their interest fit and the influencer's opinion leadership, on their purchase intention. This research also examines the moderating role of storytelling, a pervasive approach of social media influencers, in enhancing the social identity–purchase intention link. Empirical results from 467 Instagram users show that all three factors positively impact followers' intention, but social identity has a more salient effect than the others. Storytelling posts can enhance these effects. Studying influencer marketing through the social identity angle contributes to better understanding of influencer marketing effectiveness.     

Opinion leadership vs. para-social relationship: Key factors in influencer marketing

The literature on influencer marketing has identified opinion leadership of influencers and parasocial relationship with influencers as two focal constructs affecting followers' purchase intention; yet they are only studied in isolation. This research aims to provide a comprehensive understanding of the effects of the two key constructs by combining and comparing them in a model with the moderators of post characteristics, namely post type and correspondent inference. Empirical results from 409 online followers of two Instagram accounts confirm the complementary effects of opinion leadership and parasocial relationship in influencer marketing and reveal the more prominent role of parasocial relationship over opinion leadership in affecting followers’ purchase intention. These effects are moderated by post characteristics. Storytelling posts intensify both effects. Correspondent inference enhances the effect of parasocial relationship, but not that of opinion leadership. These findings point to the importance of the social aspect of influencer marketing and inform the influencer marketing research and practice on “who says what” for improving communication effectiveness.     

Is beauty always good? Effects of visual presentation of Influencer’s aesthetic labor on brand purchase intention

Aesthetic labor plays a crucial role in social media influencer marketing. Based on the theories of aesthetic labor and social media influencers, this study aims to identify the psychological mechanism and boundary conditions of the effects of visual presentation of influencers’ aesthetic labor on consumers’ brand purchase intention. The results of five studies indicate that the visual presentation of influencers’ aesthetic labor and consumers’ regulatory focus have an interactive effect on brand purchase intention. Specifically, promotion-focused consumers (vs. prevention-focused consumers) are more willing to purchase brands endorsed by influencers with a high-level (vs. low-level) visual presentation of aesthetic labor through para-social relationships. Furthermore, the homophily between influencers and consumers moderates this interaction effect. These findings have significant managerial implications for influencers and other retailing marketers to leverage aesthetic labor to win consumers’ purchase intention towards related brands.     

Response to social media influencers: Consumer dispositions as drivers

Brand managers use social media influencers (SMIs) to influence consumers' attitudes and intentions. However, there is still ambiguity about the mechanisms by which SMIs influence their followers, as well as the metrics by which their performance can be evaluated. The existing literature has restricted itself to consumers' purchase intentions in order to evaluate SMIs influence and is silent on the role of the consumers' individual characteristics in SMIs influence mechanisms. Based on these research gaps and to provide a clearer picture of the SMI influence mechanism to practitioners, the present study assesses the role of consumer characteristics such as their social media attachment (SMA), parasocial relationships with social media influencer (PSR-SMIs), and susceptibility to SMIs influence (SSMII) in driving consumer response to SMIs influence through SMI compliance intentions. Study 1 found the sequential mediational role of PSR-SMIs and SSMII in the SMA-SMI compliance intentions relationship. Study 2 found the same sequential mediation and demonstrated how SMI skepticism negatively moderates the relationship between PSR-SMIs and SMI compliance intentions. To the best of the authors' knowledge, this is the first time that this skepticism variable is being explored in the SMI literature.     

The role of influencer–follower congruence in the relationship between influencer marketing and purchase behaviour

Over the last decade, influencer marketing has become one of the most important tools for companies and brands to increase awareness, sales, or image strength. Since consumers prefer brands and companies whose image is congruent with their actual or ideal self, we could expect that consumers tend to prefer influencers whom they can compare themselves with. Therefore, congruence between consumer and influencer is imperative in influencer marketing and may indicate whether the influencer will be able to promote products to the target audience in an appealing way. Using a quantitative empirical study, we surveyed more than 7500 individuals measuring how they perceive a specific influencer's credibility, content usefulness, congruence, and purchase behaviour. The results suggest that if there is a congruence between an influencer and the follower, the impact of the influencer's experience and its content usefulness on purchase behaviour is stronger.     

Judging a book by its cover? The role of unconventional appearance on social media influencers effectiveness

Social media influencers (SMI) have gained undeniable importance as brands endorsers. However, although their credibility can be affected by the way they look, no known studies have applied appearance stereotypes to SMI's perceived attractiveness, trustworthiness, and expertise, particularly when that appearance is unconventional (e.g., use of body tattoos). Therefore, building on extant endorsement research and the Stereotype Content Model (SCM), the study examines how the use of tattoos impacts SMI's credibility, attractiveness, and effectiveness. Based on a sample of 260 young adults, a 2 x 2 x 2 (SMI gender x tattoo x domain) experimental design was conducted. Results indicate a tattoo premium effect, regardless of SMI's domain. By extending the SCM framework to the influencer marketing literature, this study contributes to both research fields, while providing valuable insights to brands and SMI.     

Followers' engagement with instagram influencers: The role of influencers’ content and engagement strategy

Influencer marketing has emerged as an effective approach for brands to connect with customers through social media influencers. Although influencer marketing has attracted increased interest from marketing researchers in recent years, relatively little is known about influencers' content and engagement strategy and its links to followers' engagement behavior. The present study addresses this gap by examining how measures of influencers' content and engagement strategy (i.e., follower count, followee count, content volume, and domains of interest) are associated with followers' engagement behavior on Instagram both independently and interactively. The study leverages a unique dataset of Instagram influencers compiled by scraping an online influencer database to test its hypotheses. The findings indicate that follower count and content volume are negatively associated with follower engagement, while followee count is positively associated with follower engagement. However, these main effects are modified by influencers' domains of interest. The findings contribute to the literature by illuminating how elements of influencers' content and engagement strategy contribute to followers’ engagement behavior on Instagram.     

Influencer marketing: Homophily,customer value co-creation behaviour and purchase intention

Given the rise in influencer marketing on social media, this paper explores how homophily between influencers and their audiences affects customer value co-creation behaviour, resulting in increased expected brand value and purchase intention. A sample of 910 respondents from the United States completed an online investigation. The results indicate that homophily positively influences customer value co-creation behaviour as well as positively correlates with expected brand value and purchase intention. Customer value co-creation behaviour plays a multi-mediating role. Para-social relationship moderates the relationship between homophily and customer participation behaviour. Overall, this study encourages further research on value co-creation in influencer marketing and can constitute a valuable reference for marketing practitioners and influencers.
