I have a campaign that I have a max bid of $0.10 for all of the keywords. All of these keywords pretty much have 0 bids on it, so I'm ranking #1-2 for most of them. Then there are a couple keywords set as inactive because the minimum bid has to be $0.15. But those also don't have any competition...so what is driving the price up on those couple keywords?
"so what is driving the price up on those couple keywords?" Probably they are less relevant to what you are advertising.
