Digital marketing is the practice of promoting products or services using digital channels such as websites, search engines, social media, email, and mobile apps. Unlike traditional marketing, digital marketing allows businesses to target specific audiences, track performance in real-time, and adjust strategies quickly based on data. It includes a wide range of techniques, such as Search Engine Optimization (SEO), Pay-Per-Click (PPC) advertising, content marketing, social media campaigns, and email marketing. With the rise of the internet and mobile devices, digital marketing has become essential for businesses of all sizes to reach customers, build brand awareness, and drive sales in a competitive online environment.
