Digital marketing is the practice of promoting products, services, or brands through digital channels such as search engines, social media platforms, email, websites, and mobile applications. It enables businesses to reach a large and targeted audience efficiently and cost-effectively. Key components of digital marketing include Search Engine Optimization (SEO), Pay-Per-Click advertising (PPC), content marketing, social media marketing, email marketing, and web analytics. Unlike traditional marketing, digital marketing allows for real-time data tracking, customer interaction, and highly personalized messaging. As internet usage and mobile device adoption continue to grow, digital marketing has become an essential tool for organizations seeking to grow their online presence, increase sales, and build lasting customer relationships.
