I've been play around Adwords and I just don't get it. The keyword that gets traffic cost me more than $0.10 in order for it to active. And then in order for them to show on the first page, I need to pay $0.50 or more. Where are the keywords people talking about that only cost $0.10 or less and tons of clicks? (Keyword I found just doesn't have traffic at all...) Someone be kind enough to reveal how to get some doable keyword?
