Funny story, I've been participating in the Amazon affiliate program for... a very, very long time. (I want to say somewhere around 10 years, but it's probably not quite that long.) I continue to receive their marketing and messaging regarding my account only to become excited to log in and finally see that I've made some money. So, can you guess how much money I've made in all these years of working with Amazon as an affiliate? I've actually received one payment of around $10. Of course given the stocks in my portfolio, I guess I could be getting a worse ROI.
So, you say, "well sure, you aren't trying very hard". Ok, what does it mean to "try hard"? Should I quit my full time job and "get rich" with Amazon? I'm not willing to do that, after all I need to feed, cloth, house, and educate my children--and that doesn't happen without income, a trust fund, or a goverment hand out like AIG got.
Actually, I've been an active affiliate for various affiliate markets and have accumulated a bit of experience that would probably be helpful to others anticipating getting into affiliate marketing more heavily.
My advice, don't quit your day job. And, learn when to give certain affiliate programs the finger--don't fall for the BS that passes as "information" in those channels...while these folks weren't clever enough to invent gaming, they certainly engage in it.
...see, I told you it was a funny story. You know what else is funny, watching people get hurt on America's Funniest Home Videos, right?
