"Q: >>Is google's adwords ban is for the account or for the domain?
AWA writes>> Knowing nothing about your account or your particular situation, I will answer this question in general terms: We shut down the accounts of advertisers who persist in not honoring the AdWords Terms and Conditions - and who may well negatively impact other advertisers, Google users, and Google itself.
As someone I know got banned recently, does anyone have any experience/evidence whether the ban is simply on the user, the domains involved, or both?
Seems pretty easy to if you wanted to get your competitors banned from adwords, if as you say, they ban URL's as well as account holder. Pay for a few clicks and then they are.
Another scenario, let's say an "adwords specialist" has 20 clients they are managing campaigns for , and now they are banned. Do you mean to tell me that all 20 cleients who have worked hard for 4 years on their URL's/sites are now banned forever because some lame "specialist" got someone else's URL banned and now the rest are permanently banned. I can't see that happening.
