Someone I know experienced an issue with overcharges having never used Adwords before and signed up with the $100 voucher. They did not realize that you will be charged beyond the voucher if you do not take steps to stop your campaigns. I recently registered with a voucher as well. Looking over the Adwords support forums, it seems as a lot of people face this problem as they were not aware of how exactly the program works. I wrote an article with basic steps to take to prevent this: http://postdotcom.com/blog/steps-to-prevent-google-adwords-overcharge/ I was wondering if any of you experienced Adwords users can correct me on any of this as I'm hoping I did not give out any false information. Thank you
The real truth only google knows, but i might say that i have used vouchers without any credit card data , setting on manual payment . It works just fine .....
