Digital marketing is the promotion of products and services through online platforms such as search engines, social media, websites, email, and mobile apps. It helps businesses connect with customers where they spend most of their time—on the internet. Unlike traditional marketing, digital marketing allows companies to target specific audiences, track results in real time, and adjust strategies quickly. Common types of digital marketing include search engine optimization (SEO), social media marketing, content marketing, email marketing, and online advertising. Today, digital marketing plays an important role in business growth because it is cost-effective, measurable, and capable of reaching a global audience.
