Endorsement on Instagram and cultural dimensions: an analysis of digital influencers

Purpose The purpose of this study is to understand the individualism/collectivism and masculine/feminine cultural aspects presented in the endorsement content made and shared by digital influencers on Instagram. Design/methodology/approach The authors conducted a cross-cultural qualitative study, collecting endorsement posts published by six fitness mega-influencers from Brazil and the USA. A total of 147 posts were assessed through the semiotic analysis of still images. Findings The authors identified that, in collectivist and feminine cultures, endorsements focus on the emotional competence of the digital influencer and the content aims at interaction, whereas in individualistic and masculine cultures, the posts highlight the informational competence of the influencer and the content focuses on the endorser's self-promotion. Research limitations/implications This study examined only two of the Hofstede's six cultural dimensions, limiting its scope. However, this study established a model that shows that the appeal of content posted by the influencer depends on individualism–collectivism dimension and the post symbolism is a result of the masculinity–femininity dimension. This study also identified the spectrum of appeal in messages and the role of advertising in building the influencer's narrative. Practical implications The authors identified cultural traits as an important criterion of congruence when choosing a brand endorser and as an element that impacts the marketing communication strategy in a social media environment. Therefore, this study suggests that organizations consider the influencer's culture as a criterion for choosing endorsers, which will guide the digital content strategy suited to the campaign's target audience. Social implications This study emphasizes the illusory effectiveness of the internet in the search for convergence, establishing that the digital environment still requires socialization that brings feelings of cultural engagement, especially through new social actors arising from virtual media. Still on the social side, this study suggests the reflection of the economic characteristics of a country together with its cultural dimensions. Originality/value This study fills a research gap from previous studies that provide empirical evidence on the impacts of cultural differences on social media behaviors. This research adds the impact of the influencer in this virtual environment to restructure the communication and information model, mold it according to the culture, acting as indicators of social transformation resulting from technological advances. This research still innovates by proposing a new methodological approach for semiotic analysis in digital media.
