Additionally, a search and analysis of scientific studies from articles published in Scopus-indexed journals was conducted. The discussion presents different perspectives on both terms, highlighting the strong links between influencer marketing and consumer purchase intention. It is concluded that Influencer Marketing, through the influencer’s credibility, is one of the most influential elements in purchase intention. Moreover, the perceived empathy between followers and influencers also emerges as a key factor in fostering emotional connections and parasocial relationships that enhance purchase intention.
