Affiliate Marketing is really hard when you are starting out. You’re going to waste a lot of time and money at the beginning. And that is assuming you ever actually start. Affiliate marketing is of those things you could spend the rest of your life “researching.”
The number 1 question any affiliate marketer gets from new people is, “What should I sell?” OK… technically the first question we get asked is “Do you really make money selling stuff on the internet” but no matter how you answer that question it devolves into “What should I sell?”
“I should go for stuff that pays me the most commission, right?”, or “big ticket items”, oh, and my favorite “I should sell stuff people actually want to buy”.
