I've got to be honest and say that I am a noob still experimenting and learning how to make money online. Google has given me a coupon code for $100 for Google Adwords. Thing is, I have no clue what to do with it or if $100 is even enough for Adwords. I have to use it by June 4, 2010 apparently. Can anyone give me some insight? Maybe there is something I can do with this?
