To understand digital marketing better, it is helpful to understand why it has become so popular. Compared to traditional marketing methods, digital marketing strategies typically have a lower cost per impression and cost per click, making them effective for smaller business marketing budgets. Many universities also offer digital marketing courses, often as part of their marketing and promotion departments. Industry associations, like the American Marketing Association (AMA), offer educational workshops and conferences to help their members develop digital marketing skills. Websites like Google Digital Garage and YouTube provide a variety of training videos on digital marketing topics such as search engine optimization, content marketing, and social media.
