I'm going to start my first Adwords campaign soon and wanted to find out some information prior to jumping into it. The way I understand it, I could automatically bid on a keyword, so I could rank much higher than if I were to manually bid (and later on find out that I have been severely out-bid). Also, I called Google and a representative told me that in order to use certain vouchers (like the $100 one I received from my hosting company), I need to deposit a specified amount of money into the account and exhaust that amount before the coupon is applied to the account. So if I need to deposit $10, can I buy a pre-paid credit card and manually deposit $10 to the account and use that in order to access the funds on the coupon? And after all balance is depleted ($10 paid and $100 on the coupon), could I delete the campaign and all the information associated with it and move on to another account? Thanks in advance, I appreciate any information that you can provide me!
