This is my first comment on your blog and I am really impressed by the quality of the content! You said that Amazon is famous but it’s complex and I agree with you upon that. As a beginner, I don’t think it’s a good idea to join complex affiliate programs. I recently published an infographic about affiliate marketing sats (https://www.earnyfy.com/affiliate-marketing-stats-2016) amazon was not the list of top affiliate networks used by affiliate marketers. I think Clickbank is good for the beginner. And another I think liked is that telling people that it’s not as easy as it sounds. Most people think making money is really and when they know the truth they call it a scam and give up.
One other positive about the Ultimate Bundles affiliate program that your readers may not have realized… They actually offer second-tier commissions too, meaning you’ll earn a share of the sales from any affiliates that you refer to the program. In this case, it’s 10% of their bundle sales during their first year as an affiliate which could be a nice earner!
