This study looks into how social media marketing affects young Indian consumers' purchasing decisions. Given India's sizable youth population and rising social media usage, it is imperative that firms and marketers comprehend this influence. The study uses quantitative techniques, such as ANOVA, correlation analysis, Chi-Square testing, and t-tests, to evaluate survey data and determine how different social media aspects affect purchasing decisions. The main conclusions show that influencer recommendations are very important and that social media marketing has a big impact on buying decisions. Although there was no general correlation between ad exposure and impulsive purchases, a linear trend did show up. Time spent on social media showed a weak positive correlation with purchase likelihood. The influence of different social media platforms did not significantly differ, though unequal group sizes limit this conclusion. The study highlights the need for tailored social media strategies and ethical considerations in digital marketing practices. Future research should explore diverse demographics, longitudinal trends, and emerging technologies to provide a more nuanced understanding of social media's impact on youth consumer behavior.
