Digital marketing is the use of online platforms and tools to promote products, services, or brands. It includes strategies like social media marketing, search engine optimization (SEO), email marketing, content marketing, and pay-per-click (PPC) advertising. Unlike traditional marketing, digital marketing allows real-time interaction, targeted advertising, and measurable results. It helps businesses reach a wider audience, engage customers, and drive sales through various digital channels. With the growing use of smartphones and internet access, digital marketing has become essential for brand visibility, customer retention, and business growth in the modern digital era.
