SMART CAMPAIGNS. I love them so so so so much.SMART CAMPAIGNS. I love them so so so so much. Has anyone ever figured out how to add NEGATIVE KEYWORDS to them? I just figured out that it lets me put a minus sign in the "products or services offered" section but don't know if that means that I can. Also would love to be able to use Ad extensions. If you have info on either of these it would be very helpful! Thanks. Sam.
