Abstract

Social media influencers express opinions on products or brands, either through commercial partnerships or in the form of unbiased content, called genuine content. To differentiate between sponsored and genuine content, influencers are increasingly choosing to include an impartiality disclosure: "This post is not sponsored." This study analyzes the combined influence of impartiality disclosure and influencer type on consumer intentions. An online experiment involving 533 participants was conducted. The findings indicate that an impartiality disclosure enhances behavioral intentions by reducing persuasion knowledge activation and increasing influencer credibility. Importantly, the positive impact is more pronounced for nano compared to micro influencers.
