I'm still very new to the world of PPC and am having a hard time driving traffic to my sites in any significant way. Last month I made a little bit of money, but now I am trying to scale my campaigns to make even more money. So, #1: when developing a campaign, how many keywords do YOU typically use? I know that I currently use too few; normally no more than 7 keywords. #2: What kind of CTR do you expect from the ads that you develop on the search engines so that you know your ad is good? Thanks!
