I recently got banned from google and managed to get me account back, there were significant amount of INVALID clicks thanks to my stupid colleguages.

So now that I have got the account back; i want to get traffic to my website via ADWORDS. Buy low cost keywords and sell high (hoping that the traffic makes clicks on my ads). I heard there was a similar program which has recieved postive response.

I need to know if this is a good idea, and is there a good chance for me getting banned. I do not want pay too much for advertising because too much traffic for a newbie is a bad idea and might result in permanent ban.

So please let me know if this is a good idea.
