In the rapidly evolving digital era, small and medium enterprises (SMEs) in developing economies like Bangladesh increasingly adopt digital marketing strategies to enhance their competitive edge and drive business growth. This study explores how digital marketing practices have been integrated into the business models of SMEs in Bangladesh and evaluates their effectiveness in achieving key business objectives such as customer acquisition, brand visibility, and revenue growth. Through a mixed-method research approach, including surveys and case studies, this article comprehensively analyses the adoption patterns, challenges faced, and outcomes experienced by Bangladeshi SMEs using digital marketing tools. The findings reveal that while digital marketing has significantly improved many SMEs’ market reach and sales performance, challenges such as limited technological expertise, budget constraints, and inadequate infrastructure continue to hinder its full potential. The study concludes with practical recommendations for SMEs to optimise their digital marketing efforts and suggests areas for future research to understand further the long-term impact of digital strategies on SME growth in Bangladesh.
