A thread at Search Engine Watch forums named Can My AdWords Ad Appear Twice on the Same Page? is a bit amusing. A member posts that his boss is mad at him, because he can not get his AdWords ad to appear more then once on a single page of the SERPs.
He discusses conducting "blackhat AdWords campaigns". By that means, setting up two seperate AdWords accounts with different information and then running the same campaign in each. Of course that might work, but sometimes, blackhats get banned. So he asks, is it worth the risk?
Moderator AussieWebmaster says "This practice has been sidelined pretty much by Google but has been known to occurr.... penalty one term gets dropped."
