Affiliate marketing is the art of marketing products, services or information for others. It doesn't require that you ever house or warehouse a single thing. But it does require that you have an audience to market those things to online. Without that audience, whether it's through search engines like Google or social media channels like Facebook, you'll find a difficult time with affiliate marketing.
The course work of a marketing program will consist of real-world and hands-on components, such as case studies of both successful and failed marketing campaigns, and simulated businesses marketed by students using the concepts they have learned. This will include diving into several computer programs like Adobe InDesign and Dreamweaver, as well as both free and proprietary website analytics software.
