Digital marketing is the use of digital channels and technologies to promote or market products and services to consumers and businesses. It encompasses a wide range of activities, including search engine optimization (SEO), content marketing, social media marketing, email marketing, online advertising, and mobile marketing. Digital marketing allows businesses to reach and engage with customers where they are, and to track the success of marketing campaigns in real-time. It is an effective and efficient way for businesses to reach a large audience and can be particularly useful for small businesses that may not have the resources for traditional marketing efforts.
