Can anyone tell me why my ads have been approved yesterday and when I checked today 0% has been served with all ctr at 0%?? Ususally I have around 15% CTR! I have set my daily budget at $20 and cpc at $1.89. Is this a time that google reviews accounts?? I am using vouchers if it helps.
One time the same thing happened to me also but when I emailed them they said me to increse the bid but your bid is high. I think you should email them they will respond very quickly.
One of the account which I am handling just underwent a review today... still undergoing... maybe your account is going thru the same process. Email google and see what they say.
