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.     

Virtual influencers as an emerging marketing theory: A systematic literature review

Over the past few years, the popularity of influencers on social media (SM) has increased, and influencer marketing has become an important element in companies' marketing strategies. This has resulted in significant interest from researchers and practitioners; consequently, the number of publications devoted to the topic of influencers and influencer marketing has risen. Simultaneously, computer-generated avatars and virtual influencers (VIs), including those using artificial intelligence (AI) and machine learning, have begun to emerge and gain popularity in the SM space. Thus far, research on these topics has been limited, with few studies examining the issue from different perspectives. Given the growing potential of VIs' inclusion in the consumer decision-making process, and this being a developing field, a comprehensive and critical review of existing research on this subject is urgently needed. In response, this study consolidates the current state of research on virtual, AI, and computer-generated influencers. A systematic review of peer-reviewed articles was conducted to identify key themes and dominant concepts. An analysis of 35 articles provides an understanding of this phenomenon, shedding light on the mechanisms underlying the appeal of VIs and their role in shaping consumer attitudes and behaviors. Based on the analysis, the main thematic streams from the study are presented. Further, research gaps have been identified, and recommendations made for future research directions.     

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.     

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.     

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.     

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.     

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.     

“I follow what you post!”: The role of social media influencers’ content characteristics in consumers' online brand-related activities (COBRAs)

The purpose of this research is to examine the underlying mechanisms through which social media influencers' (SMI) content characteristics (information, design, and technology quality and creativity) influence consumers' online brand-related activities (COBRAs) (consume, contribute, and create) through parasocial relationships and wishful identification. Grounded in the integration of the two-step flow theory, social influence theory, and power theory, a conceptual model is proposed and empirically tested using a sample of 263 social media users who had followed at least one social media influencer on social media. We analyzed the data using partial least squares structural equation modeling (PLS-SEM) and necessary condition analysis (NCA). The results reveal that three of the four dimensions of SMI's content characteristics, namely design quality, technology quality, and creativity are significant predictors of parasocial relationships. Design quality and creativity are significant predictors of wishful identification. Parasocial relationships and wishful identification are also identified as significant predictors of COBRAs. The results of NCA analysis also identify the proposed content characteristics as necessary factors required to foster COBRAs. This study offers valuable insights into how social media influencers can position themselves to be more effective in promoting brands and products through the curation of their social media content.     

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.     

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.     

Persuasive cues and reciprocal behaviors in influencer-follower relationships: The mediating role of influencer defense

In today's internet ecosystem, social media influencers serve a central purpose in the creation of a compelling online presence that engages their followers. This study examines the impact of social attractiveness, physical attractiveness, attitude homophily, actual self-congruity, and parasocial interactivity on influencer defense and purchase intention in the context of beauty influencers. A total of 689 respondents were recruited using Sina Weibo, one of the largest social media platforms in China. The results demonstrate that physical attractiveness, attitude homophily, actual self-congruity, and parasocial interactivity are crucial in affecting influencer defense. However, only attitude homophily, actual self-congruity, and parasocial interactivity emerged as significant predictors of purchase intention. The findings afford insights that can further understanding of the influencer-follower relationship in the social media environment.     

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.     

More than meets the eye: The functional components underlying influencer marketing

Influencer marketing is the practice of compensating individuals for posting about a product or service on social media. Influencer marketing is on the rise, and many marketers now plan either to start using influencers or to increase their use of them in their media mixes. Despite such growth, relatively little strategic or academic insight exists that is specific to influencers. In this article, we describe the roots of influencer marketing and the many different types of influencers that now exist. We identify influencers’ three functional components: the audience, the endorser, and the social media manager. We then detail for each of these components the different sources of value influencers potentially offer marketers. We draw on relevant academic research to offer advice about how to leverage each component strategically. We close by describing how the interplay of these functional components makes influencers a potentially powerful—and undervalued—marketing tool.     

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.     

Emoji rhetoric: a social media influencer perspective

ABSTRACT

Social media require a marketing rhetoric that embraces emerging language use and shifting communication norms. Emojis have become quintessential elements of social media communication; yet, their role in supporting persuasion attempts has not been systematically analysed. Drawing on general rhetoric literature, this paper dissects, portrays and labels social media influencers’ persuasive attempts to initiate engagement through emojis. The focus on influencers is justified because of their dual roles as marketers and active social media users. 600 Weibo posts by the top 200 Weibo influencers were collected to develop a taxonomy of emoji-based verbal moves aimed at encouraging responses in followers. The resulting taxonomy demonstrates that emoji use by social media influencers is complex and strategic and serves multiple persuasive and communicative purposes.     

Online Engagement and the Role of Digital Influencers in Product Endorsement on Instagram

Abstract

The article aims to analyze the forms of engagement generated from the endorsement of products by digital influencers on Instagram, considering the characteristics of their online posts. A qualitative approach was used to investigate digital influencers’ posts based on semiotic image analysis and the critical incidents technique. The results reinforced that digital platforms enable distinct forms of engagement by establishing new configurations that affect relationship marketing and promotion strategies. In particular, on Instagram, the development of engagement can involve four participants who play different social roles, expanding the process of value co-creation.     

When less is more: the impact of macro and micro social media influencers’ disclosure

ABSTRACT

There are growing discussions of social media influencers and their effectiveness in endorsing products. Further, recent policy regulations are requiring social media influencers to disclose sponsored content when using a form of native advertising. This research examined the effect of macro-influencers (high likes) and micro-influencers (low likes) and their disclosure of native advertising sponsorship on consumer evaluations of products. Results from a 2 × 2 experiment first show that consumers exposed to the micro-influencer condition report higher levels of product knowledge, and consumers exposed to the disclosure condition reported the products endorsed by social media influencers to be more attractive. The results also show that when exposed to micro-influencers who disclose, consumers have higher levels of purchase intentions than when exposed to macro-influencers who do not disclose, as well as higher purchase intentions than for posts where sponsorship is not disclosed by influencers. The important findings of this research for theory, practice and policy are discussed.     

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.     

“I'll buy what she's #wearing”: The roles of envy toward and parasocial interaction with influencers in Instagram celebrity-based brand endorsement and social commerce

Companies increasingly leverage Instagram as a channel for brand management, consumer services, and social commerce. This study addresses the dynamics of interaction among brand-related user-generated contents (UGC) posted on Instagram, social media-based brand communication with Instagram celebrities (parasocial interaction [PSI] and envy), and consumers' characteristics (social comparison tendency, compulsive buying tendency, and materialistic envy). Three between-subjects experiments (Experiment 1: N = 121; Experiment 2: N = 106; Experiment 3: N = 377) were conducted to test the effects of Instagram influencers and their branded-UGC on consumer behavior outcomes. Experiment 1 employed a 3 (branded content type [Instagram influencer's photo type]: selfies vs. photos taken by others vs. group photos) x 2 (gender: female vs. male) factorial design. Experiment 2 employed a 2 (content generator type: Instagram celebrity vs. mainstream celebrity) x 2 (gender: female vs. male) factorial design. Experiment 3 deployed a 2 (branded content type: photos listing products vs. photos showing models) x 2 (content generator type: commercial brand [corporate] vs. Instagram celebrity [human]) factorial design. Experiment 1 indicates Instagram influencers' photo types and gender moderate the effects of envy toward and PSI with them on consumers' intention to buy the products Instagram influencers are wearing. Experiment 2 shows content generator types and gender moderate the effects of envy and PSI on source trustworthiness perception. Experiment 3 demonstrates branded content types and content generator types moderate the effects of consumers' physical appearance social comparison tendency, compulsive buying tendency, and materialistic envy on brand trust. This study makes theoretical contributions to the literature on retailing and consumer services as well as provides managerial implications for Instafamous-based influencer marketing and social commerce in Web 2.0 environments.     

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.
