Say I put my budget to be £15 a month. But at the moment I have like 3£ on my card. How will this affect me, WHat if google goes to charge me and my card is empty? Also Hostgator is giving 25$ worth of credit. Is this totally legit, or is there a catch, like I need to spend so much....
Don't advertise if you don't have money to do it.You really don't want google on your neck. There isn't any catch with that free 25$ voucher probably,you can use that money for advertising without any worries.
