So, I had plenty of time to learn all about internet marketing.
My very first foray into adwords + CPA was a HUGE success. I took the "webfetti" offer on Azoogle, it's a myspace toolbar, bid on one keyword on the content network "myspace", and proceeded to make about $5,000 that month off of that ONE KEYWORD.
I quit my job shortly after that. The webfetti gravy train didn't last long, and I ventured into other niches, insurance, information, education, and dating.
Dating is still my bread and butter. The networks pay $2-$4 for a free sign up, and believe me, convincing single guys to sign up for a free lead in hopes they'll get laid is, and always will be, an easy sell.
One of these days we'll look back and call these the "Good Old Days" of affiliate marketing.
So for you guys who aren't getting involved and trying new things, I recommend you start now. My first attempt was a huge success. I've had many failures since then, but I've learned from them all.
It's only going to get harder from this point on, so I'd recommend that you new guys get started as soon as possible. There's money to be made right now. No one knows where affiliate marketing will be in 10 years, I'm cashing in while I can, I recommend that you do the same.
