Abstract

Influencer marketing and communication are experiencing rapid growth, driving the expansion of research aimed at understanding how they work. The profiles of so-called influencers are highly diverse, and their impact varies depending on the context in which they operate. In this regard, platforms such as Instagram have consolidated their position as ideal spaces for brands to integrate these profiles into their communication strategies. To address the dynamics explained above, this study focuses on examining how researchers approach the study of this field, using a systematic review of the scientific literature as its methodology. Recurring keywords, research approaches, designs, and instruments used to achieve a variety of objectives related to understanding the phenomenon are analyzed. In addition, the subject matter of these publications is investigated. The results show that, far from declining, research in this field has experienced steady growth over the years, raising various concerns within the scientific literature related to the need to address aspects such as transparency in influencers' publications, the authenticity of their content, the effectiveness of the communication strategies implemented, and the real impact on the audience in a more comprehensive and detailed manner.
