Digital transformation continues to redefine how small and medium enterprises (SMEs) compete across Asia's rapidly evolving emerging economies, making the strategic adoption of digital marketing tools increasingly central to business survival and growth. This systematic literature review synthesizes evidence from 30 peer-reviewed studies drawn from ten Asian nations, selected from an initial pool of 194 Scopus-indexed articles through a structured PRISMA 2020 protocol covering the period 2019 to 2026, to examine the adoption, effectiveness, and implementation challenges of three core digital marketing tools: social media marketing, search engine optimization (SEO), and email marketing. Grounded in the Technology Acceptance Model (TAM), the Technology-Organization-Environment (TOE) framework, and the Resource-Based View (RBV), the review addresses three research questions concerning tool effectiveness on business performance, contextual moderating factors, and key implementation challenges. Social media marketing emerges as the most widely adopted and most consistently effective tool, with positive effects on SME performance confirmed across Indonesia, India, Malaysia, Pakistan, and beyond. SEO and email marketing, while effective, remain underutilized and underresearched in Asian SME contexts. Effectiveness is moderated by digital literacy, management support, firm size, and government infrastructure, while principal implementation barriers include financial constraints, technical knowledge gaps, content inconsistency, and difficulty measuring return on investment. These findings carry significant implications for SME practitioners, policymakers, and management educators seeking to accelerate inclusive and sustainable digital marketing transformation across Asia's diverse emerging markets.
