Abstract

This research explores the intersection of marketing, technology, and sustainability in shaping consumer behaviour and driving innovation within the Indian context. With a growing emphasis on digital transformation and the increasing consumer demand for sustainable products and services, this study seeks to understand how technological advancements such as AI, blockchain, and IoT are influencing consumer expectations, service quality, and organizational strategies across diverse sectors, including healthcare, retail, and FMCG. Utilizing a mixed-methods approach, the study gathers data from 1,000 respondents across six metropolitan and five tier-II cities in India. The research examines consumer responses to digital marketing and sustainable practices, evaluating the impact of service quality on customer satisfaction and retention. The findings highlight the growing importance of sustainability in consumer decision-making, as well as the role of digital technologies in enhancing operational efficiency and consumer engagement. The study also identifies barriers to the adoption of digital and sustainable practices, particularly in tier-II cities, and provides policy and industry recommendations for businesses seeking to integrate green technologies and ethical branding into their marketing strategies. The research concludes with insights into the future of interdisciplinary innovation in India's evolving consumer landscape and outlines areas for further study, including the impact of the digital divide, the long-term effects of sustainability on brand loyalty, and the integration of advanced technologies in traditional industries
