i was registed a account adword with Coupond all keyword activate but my ads dont show on google please tell me what problem
Maybe it's because of your CPC rate? If you are paying low CPC on a highly comepetitive keyword or keyword phrase. Usually it has something to do about this. Often it's better to bid on low CPC keywords, that gets a good amount of searches on Google. You should do some keyword research, before anything else!
From where you check it? from google stats? Do you see impressions? When did you start running your ads? More info will appreciated,
My guess would be that your CPC is too low. New accounts often have to pay more for clicks than better established ones, so you may have to set your bids higher at first and then lower them later,
did you have any other adwords account before? it seems like google smelled somethig funny with this account. contact adwords and ask for explanation
