I’d stick with Amazon if I were you. All of my Amazon sites only have Amazon affiliate links. If you use Google Adsense display ads on your site, you’re literally taking people away from your site for the sake of just a few cents with these type of ads. If you direct them just to Amazon, then you have a greater chance of earning more money from that click.
If you are going to learn how to do affiliate marketing and you want to make real money (not just play at it as a hobby) then you need to learn from Omar and Michael. Why? Because I have seen firsthand how they can not just send tons of traffic but snag tons of sales. Whenever they have promoted any of my offers I'm amazed at the flood of sales notifications that come in. To get both these guys give you their blueprint for this price is crazy. Buy it but please treat it like you spent $200 on it so you value the info, use it and profit from it!
