In the growing area of digital marketing, influencer marketing has become a crucial catalyst for consumer behavior, especially in the organic food industry. This study investigates the impact of influencer marketing on social media awareness and purchase intentions for organic food items through a systematic literature review and bibliometric network analysis. The study looked at 156 research papers from Scopus published between 2018 and 2024, using methods like Citation Network Analysis and Global Citation Score Analysis, to analyze them. The results demonstrate that influencer reputation, competence, and content authenticity significantly bolster customer trust, social media engagement, and purchasing behavior. Identified emerging themes encompass the increasing influence of micro-influencers, the tactical use of narrative, the cultivation of parasocial relationships, and the ascent of AI-generated virtual influencers. This study, rooted in the Theory of Planned Behavior and Social Learning Theory, highlights the essential function of trustworthy influences in cultivating consumer loyalty and encouraging sustainable consumption patterns. The study provides theoretical insights and practical approaches for utilizing influencer marketing to enhance organic food consumption while also suggesting future research avenues, such as cross-cultural examinations and the investigation of technology’s changing influence on influencer marketing.
