The document compares digital marketing and traditional sales promotion methods. It discusses that traditional marketing relies on mass media like TV, magazines and advertisements to reach large audiences, but it is costly. Digital marketing uses methods like email, blogs, social media, pay-per-click ads and mobile marketing, and it allows for more targeted and measurable promotion. While traditional marketing has high exposure, digital marketing generally has lower costs, higher engagement and better return on investment. Both methods have benefits depending on a company's needs.
