You're joking, right? The company I work with (my client) just paid their top affiliate $6K. 15% of the referrals he sent in the last month. Know where he drives those sales from? His blog. lol.
None of the top affiliate performers I work with promote Amazon. Bezos runs the worst affiliate program on the internet. Commission is too low and cookie duration too short.
Blogging isn't dying. Neither are affiliate programs. Internet marketers aren't where the real money is, either. They're just the skeevy get rich quick scam corner of the classifieds.
