I started a campaign on google adwords paying 1 cent per click, and had thousands of keywords. My click through rate was low, but because of all the keywords, I was getting thousands of impressions of my add in searches. I only spent 97 cents and got 14 clicks. Then after a couple hours all my keywords were deactivated, and they want me to raise my minimum bids to 5 or 10 dollars per click. Is this a scam or what? I had great traffic going for a while, can I get it going again?
