My client started Adwords over Overture some time ago at my suggestion. I don´t know much about adwords but I do know Overture sucked and wasn´t bringing him the biz. He started it and was really happy at first. Now, get this. Initially he was advised by AW to pay €8 a day.Now it is €90 a day. I mean that is just silly! Is it possible or recommended to maybe do week on and week off?
I never go by Adwords recommendations. I find that if you go with Adwords you will spend the most amount of money and receive about the same traffic.
