Greenfluencers as agents of social change: the effectiveness of sponsored messages in driving sustainable consumption

Abstract

Purpose This study aims to examine the role of message appeals (concrete vs abstract) posted by greenfluencers in determining their behavioral intention toward the sponsored sustainable product. This study examined the underlying mechanism of message authenticity and product sustainability image in this relationship. This study also investigated the boundary condition of product type (utilitarian vs hedonic) in the effect of sustainability message appeal on purchase intention. Design/methodology/approach Four studies were carried out. One field experiment on Facebook and three scenario-based online experiments were conducted to test the proposed relationships. Findings This study found that a concrete message appeal results in a higher purchase intention of the promoted product than an abstract message appeal. This effect is a result of message authenticity and product sustainability image. Furthermore, product type moderates the impact of message appeal on behavioral intention via message authenticity and product sustainability image. Research limitations/implications This study contributes to the literature on influencer marketing, sustainability communication and the persuasion process. Practical implications This study’s findings provide insights for greenfluencers and firms that leverage greenfluencers to promote their sustainable products on social media. Specifically, it lays out how the sustainability message should be framed to be persuasive. Originality/value This study findings offer novel insights for greenfluencers and firms in developing effective message strategies to promote sustainable products on social media.

Colorful candy, teen vibes and cool memes: prevalence and content of Instagram posts featuring ultra-processed products targeted at adolescents

“…The rapid global diffusion of social media has introduced substantial transformations in marketing management models (Kapoor et al , 2023; Reed et al , 2012; Singh and Sharma, 2022; Vollero and Valentini, 2022). Social media has become the most profitable channel for global marketers (Nielsen, 2022), who spend a growing share of their advertising budget on social media marketing to increase brand awareness, improve brand image, encourage interactions with users and boost sales (Cavusoglu and Demirbag-Kaplan, 2017; Felix et al , 2017; Michaelidou et al , 2022).…”

Home cooking in the digital age: When observing food influencers on social media triggers the imitation of their practices

“…Despite these criticisms, recent research has shown that influencers can impact society positively. “Greenfluencers,” for example, can encourage the consumption of more sustainable products (Kapoor et al, 2023) or the adoption of eco‐friendly travel practices (Yasin et al, 2023). Some influencers confront gendered ageism (Veresiu & Parmentier, 2021) and challenge standard beauty norms by explicitly advocating for bodypositive movements (Cwynar‐Horta, 2016), thereby empowering their followers (Bussy‐Socrate & Sokolova, 2023).…”

Pawsitively powerful: Why and when pet influencers boost social media effectiveness

“…Influencer marketing can be defined as a "strategy in which a firm selects and incentivizes online influencers to engage their followers on social media in an attempt to leverage these influencers' unique resources to promote the firm's offerings" , Hub, 2023). Previous research has proposed several solutions to this issue, such as sharing more original content and ideas (Casaló et al, 2020;Ki & Kim, 2019;Leung, Gu, Li, et al, 2022), using more sensory language (Cascio Rizzo, Berger, et al, 2023) and high-arousal language (Cascio Rizzo, Villarroel Ordenes, et al, 2024), following fewer others (Valsesia et al, 2020), sharing visual content or sponsoring products congruent with followers' interests (Argyris et al, 2020;Belanche et al, 2021), using facial expressions (i.e., broad smile) that fit with the endorsed product (Shuqair et al, 2024), and adopting a concrete (vs. abstract) message appeal (Kapoor et al, 2023). A common thread in all these studies is the emphasis on human influencers-or more recently, virtual (computergenerated) versions (Sands et al, 2022).…”
