I've heard from so many affiliates that they "tried" Google Ad Words and it "didn't work" for them, so they quit after only a brief period of blind and random trial and error. The same thing happened to me when I first started dabbling in pay per click. I found that Google Ad Words wasn't as easy as I thought and there was a substantial (and potentially expensive) learning curve.
I didn't make ANY real money in Google Ad Words until after I had found, studied and implemented Perry's Marshall's Google Ad Words techniques.
Since I learned the secrets of how the Google Ad Words system works, I have driven hundreds of thousands of clicks to my own websites and to the websites of other affiliate products I promote, with return on investment (ROI) of 300%, 400% even 500% on some of my campaigns.
Believe me, Ad Words DOES WORK - it's a powerful and FAST marketing tool - but there's a learning curve and you can "lose your shirt" if you don't know what you're doing - especially with the changes that have recently taken place in Google's landing page policies.
Perry Marshall put together a FREE mini course called, 5 Days To success with Ad Words, which shows you how to shorten the ad words learning curve, make fewer "newbie mistakes" and get your campaigns into the profit-zone faster, with less risk.
Here's the webpage where you can get Perry's Free ad-words mini course:
P.S. By the way, the rules at Google have changed, but The Google Cash Method STILL works if you do your homework and find the right keywords and write great ads. This is the method Clickbank affiliates use to make money even if they don't have a website. I will write more about this in the near future in the Affiliate training center area, or visit www.GoogleCashMethod.com
