Can you believe it? They banned me from using Adwords. It happened almost a year ago. Our company was offering free beer using Adwords for St. Patrick's Day. Well it proved out to be against the guidelines, oh well. Now, as a matter of a fact i don't work for that company any more and changed the whole site idea from Nightlife to Fashion. Still Adwords support guys from London refuse to reactivate my account. Miva and Overture don't do the job nearly the same like Adwords so i feel like a criminal who can never be pardoned and got a capital punishment Well its their business, but if you look at the situation as a human being, this system is so evil.
Nothing against, but they don't want their world's top trademark name associated with alcohol, tobacco, gambling, guns... See Full list here: https://adwords.google.com/select/contentpolicy.html
Bit Off-Topic: How's MIVA for you (why you are using that)? They got nice amount of fraud/low converions (even I experienced this).
