Digital marketing refers to the promotion of products or services using digital channels such as websites, search engines, social media, email, and mobile apps. It has become a vital part of modern business as more consumers rely on the internet to find information, compare products, and make purchases.

Unlike traditional marketing, which uses print media, TV, and radio, digital marketing offers a more targeted, measurable, and interactive approach. Businesses can reach specific audiences based on interests, demographics, location, and behavior. Key components of digital marketing include Search Engine Optimization (SEO), which improves website visibility in search results; Pay-Per-Click (PPC) advertising, where businesses pay for each click on their ads; Social Media Marketing (SMM) to engage with users on platforms like Facebook and Instagram; and Email Marketing, which allows direct communication with customers.
