Well i just wanna share my experience with you guys although i am not yet sure that this is the real reason why my ads are no longer displaying on the sponsored search results in google. I have bought multiple activated adwords account to advertise one site. been doing good for more than a month. Today, my ads are no longer displaying. At this point of time, i really have no idea what caused this. Not a campaign budget issue i'm sure as i have enough of it. So anybody experiencing the same thing during the last 24 hours?
You probably have been banned due you'vr violated TOS, now you can not advertise using AdWords anymore.
no, when you are banned, you are free to login on your account, but the ads will never show again even you try to create new accounts.
Even if i try to create new accounts....ok, so what do they ban. The IP, Credit card, account....or what
your credit card, your site layout/content (if you try move your site to a new domain will not help you), the keywords you used, your ad text - they also use geo-targeting (based on your IP) to track you and each time they detect you (when you try to create a new account) they get more data about you to help detecting you the next turns. Their system is very good - I never heard of someone that could get in again after get banned.
