It adopts an inductive approach, employs a case study design, and uses coding schemes for analysis. The goal is to gain insights into their strategies and behaviors.

Conclusion: This study explores how social media micro-influencers fabricate authenticity and trustworthiness to engage their audience. Influencers like Johanna Johnson and Alva Blomdahl use tactics like consistent posting, transparent sponsored content, and genuine engagement. Drawing on consumer culture theory, the findings emphasize the significance of authenticity, personal connections, and transparency in establishing credibility and trust. The research contributes to understanding the impact of consumer culture on influencer marketing and consumer behavior.
