The Impact of DigitalMarketing on Small and Medium Enterprises (SMEs) Growth: A Systematic Review

Introduction: Small and Medium Enterprises (SMEs) are a cornerstone of global economic development but often face barriers such as limited resources, restricted market access, and high competitive pressure. Digital marketing has emerged as a transformative tool that enables SMEs to enhance visibility, improve customer relationships, and achieve sustainable growth through cost-effective online strategies. Methods: This systematic review analyzed 52 peer-reviewed empirical studies published over the past decade. Inclusion criteria focused on research that explicitly examined the relationship between digital marketing practices—such as social media marketing, search engine optimization, email marketing, and online advertising—and the growth metrics of SMEs. The review adhered to PRISMA guidelines to guarantee methodological rigor and dependability. Results: Findings indicate a strong positive correlation between digital marketing adoption and SME growth indicators, including sales performance, market expansion, customer retention, and brand awareness. The effectiveness of digital marketing interventions was found to be moderated by factors such as managerial digital competence, organizational readiness, budget allocation, and external market conditions. Despite the benefits,SMEs continue to face challenges in digital literacy, measuring return on investment, and keeping pace with evolving digital platforms and consumer behavior.
