This paper investigates the influence of digital engagement strategies on brand loyalty in the FMCG sector among suburban consumers in Bhandup and Mulund, Mumbai, India. Using a case study approach, the research analyses how digital marketing tactics-such as social media campaigns, influencer collaborations, and e-commerce promotions-impact consumer engagement and loyalty. Focusing on younger, educated segments, the study reveals that digital platforms significantly shape brand perceptions and drive purchase decisions. By assessing the effectiveness of these engagement strategies, the paper highlights consumer preferences, price sensitivity, and brand-switching tendencies in response to digital advertising efforts. These findings offer insights into how FMCG companies can effectively use digital channels to foster brand loyalty in a diverse and evolving market.
