This study examines the effectiveness of marketing strategies employed by Amul, a leading dairy brand, in driving Sales Growth within its product line. Three key objectives guide the investigation: evaluating the impact of Product Diversification, comparing Traditional and Digital Advertising strategies, and analysing the influence of End-Use differentiation on Sales Growth. Leveraging a Secondary Research Approach, Sales Data spanning multiple years are compiled and subjected to statistical analysis using T-test methodology. The findings reveal significant insights into Amul's marketing landscape. The study unveils a noteworthy distinction in Sales Growth resulting from Product Diversification strategies between Adult and Children Products. While both segments exhibit positive growth, Adult Products demonstrate a more pronounced impact, suggesting potential areas for strategic emphasis. Additionally, the analysis highlights a significant difference in Sales Growth between Traditional and Digital Advertising strategies, with Traditional channels showing slightly higher mean Sales Growth. This underscores the importance of a balanced approach that leverages the strengths of both advertising mediums. The study underscores the significance of considering the End-Use of Products in influencing Sales Growth outcomes. Final Products exhibit higher mean Sales Growth compared to Intermediate Products, signalling opportunities for Amul to further enhance its consumer-facing product offerings. Based on these findings, several recommendations are proposed to optimize Amul's marketing strategies. These include allocating resources towards diversifying offerings targeted at the adult demographic, adopting a balanced approach to advertising that integrates Traditional and Digital channels, and exploring opportunities to enhance the portfolio of Final Products
