I own around 30 websites all with adsense banners on them, but only make about 3$ a day! Any help would be greatly apreciated. Some of my sites are 1st in Google and get lots of hits but hardly any clicks.
What I have done is try to write content that my users are attracted to. Basically, I have learned that if my visitors enjoy reading my content they will like the ads that display from the content I have. I hope that makes sense to ya. If your sites is about finding free desktop widgets to download you should write about that and get banners displaying that show those widgets from website and chances are enough users will click on those widget company banners.
You can do ads placement. if your 30 site banner all are in footer, you can earn double even more. more deep red = the best area next orange area yellow area white area = can't suck more for normal web site official page:https://www.google.com/adsense/support/bin/answer.py?answer=17954 for forum official page:https://www.google.com/adsense/support/bin/answer.py?answer=43868 for blog official page:https://www.google.com/adsense/support/bin/answer.py?answer=43869
