With that clickthrough rate it sounds like your ad placement is very poor, or you've got so much other distracting stuff on your pages that your visitors aren't noticing your ads. Try rearranging things a bit. I usually aim for an absolute minimum CTR of 10%.
u are not getting high paying ads....... look into ur keyword..... my worst blogs get me 20cts per click.
I think the average or good enough CTR should be around 5 to 8% . Maybe i am wrong but many people supports this...
kinda like a low peak now. if u target Asia now, which is coming to CNY, then ads related to CNY goodies, holidays, dinners, will get u good EPC as advertisers will try to grab a slick of the festive earnings.
