Digital marketing is the use of electronic media, particularly the internet, to promote or sell products or services. It is a broad term that encompasses a wide range of activities, such as search engine optimization (SEO), search engine marketing (SEM), social media marketing, content marketing, email marketing, and mobile marketing.

Digital marketing is important for businesses for a number of reasons. First, it allows businesses to reach a wider audience than ever before. In the past, businesses were limited to reaching customers through traditional channels, such as print advertising, television advertising, and direct mail. However, digital marketing allows businesses to reach customers all over the world, 24 hours a day, 7 days a week.

Second, digital marketing is more cost-effective than traditional marketing. With digital marketing, businesses can target their ads to specific demographics, interests, and behaviors. This means that businesses can reach the right people with the right message, which can lead to better results and a higher return on investment (ROI).
