Hello, I have been reading many forums on adwords , but still confused . Everyone has different sayings on this . Well my question is , If i create one new adword account, add real cc/vcc , one domain/url , 1.But for billing info, i use a free $100 Voucher /code. Then will google charge my cc/vcc for the ads or will it use from the voucher first? 2. If i create multiple adword accts, for diff url/domain, different vcc/cc , can i use different vouchers/coupons for them too?? and not spend a single penny from cc/vcc. (but cc/vcc are real and have money) ??
