This chapter investigates the revolutionary impact of social commerce and influencer networks within modern digital retail landscapes. Social commerce signifies a fundamental transformation from conventional e-commerce models by merging social media capabilities with transactional processes, thereby establishing dynamic, community-centric purchasing environments that harness interpersonal networks and social influence mechanisms. The study examines how prominent social media platforms—including Facebook, Instagram, TikTok, Pinterest, and YouTube—operate as specialized retail conduits, each providing distinctive features for audience interaction and sales optimization. The research analyzes influencer-driven commercial frameworks, evaluating the comparative efficacy of micro-influencers against macro-influencers in establishing credibility and stimulating purchasing behaviors, while also exploring the developing significance of artificially intelligent virtual influencers. Community participation elements, encompassing user-created content, social validation systems, gamification-based retention strategies, and collective purchasing mechanisms, are examined regarding their influence on trust development and consumer decision-making processes. The investigation demonstrates that authenticity constitutes the primary challenge and potential advantage throughout social commerce frameworks, with thriving platforms and content creators consistently emphasizing genuine value delivery rather than exclusively transactional engagements. These discoveries enhance comprehension of how social connectivity and commercial enterprise merge through advanced technological infrastructures to generate novel possibilities for substantial consumer-brand partnerships.
