In online affiliate marketing course, they will teach you everything you need to know to run a business online everything you need, even you'll learn how to create affiliate campaigns from scratch even if you currently don't have an audience or a list and the best part is you don't even need your own products to make money with affiliate marketing.
Outbrain is not necessarily the network of choice, it was just an example. As for tracking the ROI usually you'll want to track campaigns in Google analytics and track clicks on affiliate links as event and average value/email or you'll want to duplicate the post and run paid traffic to the duplicate so you know exactly what the conversions are as you can put them in separate email lists etc too.
Access to a computer, spreadsheet software (Excel or Google Spreadsheets), an email account, and an eager and open mind! Additionally, I ask that you have at least some online following already. It can be a small one, but you shouldn't be starting from scratch when getting access to this course. If you're not sure what your business is about yet, that's the most important thing to figure out first!

This leaves the greater, and, in case of cost per mille, the full risk and loss (if the visitor cannot be converted) to the advertiser.
