Social media, such as Facebook, offer brands the opportunity to reach their target audience in a less obtrusive way than traditional media, through sponsored posts. Regulations require marketers to explicitly inform consumers about the commercial nature of these posts. This study addresses the effects of sponsorship disclosures by means of a 2 (no disclosure vs. the sponsorship disclosure ‘Sponsored’) × 2 (source: celebrity endorser vs. brand) experiment. Results suggest that a sponsorship disclosure only influences the use of persuasion knowledge when the post is disseminated by a celebrity. Moreover, a disclosure starts a process in which the recognition of advertising (i.e., the activation of conceptual persuasion knowledge) causes consumers to develop distrusting beliefs about the post (i.e., higher attitudinal persuasion knowledge), and in turn, decreases their intention to engage in electronic word of mouth.

New social actors have emerged with the social media. Among them, we highlightedthe digital influencers, people who have millions of online followers, andinduce them in favor or against products and brands to be consumed. Therefore,we aimed to analyze this endorsement process carried out by digital influencers intheir online profiles, having as research field the fitness market that encouragespeople to evaluate and work tirelessly in their bodies. We used the Semiotic ImageAnalysis to investigate the postings of three Brazilian digital fitness influencersand identified four categories that configure the post format: body exposure, bodyextension, interaction between influencer and brand/product, and interaction betweeninfluencer and followers. By means of these categories, we identified thatthese influencers act as brand avatars, creating an intense link with these products,exposing their bodies in advertisements and extending the meanings of theirgood shape to endorsed goods and services.

Increasingly, Instagram is discussed as a site for misinformation, inau-thentic activities, and polarization, particularly in recent studies aboutelections, the COVID-19 pandemic and vaccines. In this study, we havefound a different platform. By looking at the content that receives themost interactions over two time periods (in 2020) related to three U.S.presidential candidates and the issues of COVID-19, healthcare, 5G andgun control, we characterize Instagram as a site of earnest (as opposedto ambivalent) political campaigning and moral support, with a rela-tive absence of polarizing content (particularly from influencers) andlittle to no misinformation and artificial amplification practices. Mostimportantly, while misinformation and polarization might be spreadingon the platform, they do not receive much user interaction.
