I keep getting about 5 cents per day from no clicks. I changed the ads on the site today to see if I can get more $$$ but still not making no money at all... we are driven over 500+2k aday.
If the ctr is low, then chances are that you will get some cents for no clicks (Is it an incentive by the google). Try to optimize the contents with high paying keywords and position your ads at vantage points and now see how it works?
