how much you get paid actually depends on your niche. you probably don;t have a niche that pays much. what is your niche BTW?
there is no help ... is only God for poor people ... your niche is the problem i think, huge huge traffic is the solution or another niche ...
Niche is important yes. I see that you have channels on each ad block e.g. mp3 I would filter ebay.com from your adsense filter. Generally nice sites like ebay gets "Great" quality score so they don't pay much advertising. Stubhub ad showing on your site is 50/50 "Tickets" related keywords are competitive but well known site like that probably pay less. Some tips on how to filter your adsense ads, my blog http://www.mulamaker.com/my-way-of-increasing-adsense-earnings-with-competitive-ad-filter/
Addition: My main source of income is ticket affiliate so I heavily advertise for ticket related keywords.
I guess that I should be happy then with my 1 click for $1.16. I would rather have the 20 clicks times this amount though.
