The rapid advancement of digital technologies has transformed retail business models worldwide. Consumers increasingly interact with brands through multiple touchpoints, including physical stores, websites, mobile applications, social media platforms, marketplaces, and customer service channels. This evolution has led to the emergence of omnichannel retailing, a strategy that integrates all customer interaction channels into a seamless and unified shopping experience. This study examines the impact of omnichannel retailing strategies on customer satisfaction, operational efficiency, brand loyalty, and business performance in the digital economy. Using a quantitative research approach involving 500 retail organizations, the research investigates the effectiveness of omnichannel integration and its contribution to sustainable competitive advantage. Findings indicate that retailers implementing robust omnichannel strategies experience higher customer engagement, increased sales conversion rates, improved customer retention, and enhanced organizational performance. The study concludes that omnichannel retailing has become a critical success factor for modern retailers operating in increasingly digital and customer-centric markets.
