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.
For example, if I talk about how cool a product is, and then you find out that I’m an affiliate for them, wouldn’t you as a conscientious observer become skeptical as to whether my information is biased, if perhaps I’m only saying how cool something is because I can get paid for it? Wouldn’t that make you question my integrity with other things I say as well?
