Jason – so happy to hear the tutorial is helping! Affiliate marketing was a huge break for me and I’m sure it can be for your son too. Whatever products/services he ends up selling, just make sure he is excited about the industry he is – it takes a long of time creating content and it will keep him motivated especially when he gets his first sales.
The problem with affiliate marketing, like many other home business options, are the so-called gurus and get-rich-quick programs that suggest affiliate marketing can be done fast and with little effort. Odds are you've read claims of affiliate marketing programs that say you can make hundreds of thousands of dollars a month doing almost nothing ("Three clicks to rich!"). Or, they suggest you can set up your affiliate site, and then forget it, except to check your bank deposits.
