This study examines the impact of digital transformation on the marketing strategies of small and medium-sized enterprises (SMEs) in Morocco. Focusing on key marketing dimensions such as offer customization, customer service efficiency, marketing cost reduction, performance analysis, and overall marketing effectiveness, the research aims to explore the benefits SMEs gain from adopting digital technologies. A quantitative approach was used, involving a sample of 200 marketing managers from SMEs that have integrated digital tools into their marketing strategies. Data were collected via surveys distributed through email, social media platforms, and in-person meetings. The findings reveal that digital transformation positively affects offer customization, customer service efficiency, performance analysis, and overall marketing effectiveness. However, no significant relationship was found between digital transformation and marketing cost reduction. The results emphasize the importance of digital tools for improving SME competitiveness and highlight the need for strategic investment in digital technologies. This study provides valuable insights for both practitioners and researchers, recommending that SMEs adopt digital transformation in a structured manner to optimize their marketing strategies and enhance customer relations in an increasingly competitive environment.
