Influencer marketing is a marketing strategy used in the digital ecosystem to promote products or services through influencers or influential people in the digital environment. These influencers can be celebrities, experts on a particular subject, or simply people with a large follower base on social media. Thus, influencing followers can help promote a brand or product more effectively than traditional marketing. Although influencer marketing is a central concept in current trends in marketing strategies, most marketing managers have yet to incorporate it into their agenda. As a result, more research is needed to provide reliable and accurate data on influencer marketing to empower marketing managers and their teams with the necessary knowledge. Based on this research gap, a systematic bibliometric literature review was conducted. This research essay aims to assess the challenges and opportunities, thus building a reference framework for influencer marketing in the digital ecosystem.
