hi i have been using adsense for domain on two of my domains currently. (will be developing websites soon....). one of the domains is useless, the other one gets 5 impressions on the worst days and on some days it goes up to 20. but there are no clicks. so far i haven't earned more than $1 in the past 2 weeks even after so many impressions. am i doing something wrong?! is there a way to maximize earnings from adsense from domains?! help would be apreciated
