One challenge in creating a personal brand is convincing consumers that it is authentic. Brands perceived to be inauthentic will have difficulty engaging with consumers; thus, the brand may not be long-lasting. This is also important for influencers, as they are a type of personal brand. Therefore, it is essential to consider the authenticity that is necessary for influencers when creating their brands. This study adapts the dimensions of advertising content value, and it examines the direct and indirect effects on influencer authenticity and followers' trust, attitudes, and purchase intentions. The study reached out to 445 social media users interested in beauty and personal care products. The results indicate that the perceived entertainment and perceived informativeness of the influencer's post content have a significant positive effect on influencer authenticity. Moreover, the results also show that influencer authenticity plays an important role in trust in and attitude toward branded posts. Finally, trust in and attitude toward branded posts lead to purchase intention.
