The rise of influencer marketing: impact on consumer trust and purchase decisions

Abstract

Influencer marketing has emerged as one of the most powerful digital marketing strategies in the contemporary business environment, fundamentally transforming how brands communicate with consumers. With the rapid growth of social media platforms such as Instagram, YouTube, and TikTok, individuals with substantial online followings commonly referred to as influencers have gained the ability to shape consumer perceptions and influence purchasing decisions.

This study examines the impact of influencer marketing on consumer trust and purchase behavior, with a specific focus on authenticity, relatability, and credibility. A mixed-method research design has been adopted, incorporating primary data collected from 100 respondents across different demographic segments. Statistical tools such as correlation analysis and chi-square tests have been used to validate the hypotheses.

The findings reveal a strong positive relationship between influencer credibility and consumer trust, which significantly influences purchase decisions. Micro-influencers, in particular, are found to be more effective due to their perceived authenticity and closer connection with audiences. However, concerns related to over-commercialization, misleading promotions, and lack of transparency remain critical challenges.

The study concludes that influencer marketing is a strategic tool for modern branding, provided it is implemented ethically and aligned with consumer expectations. The research contributes to the growing field of digital marketing by offering empirical insights into consumer behavior in the age of social media.
