My Sept not too good as well. Any holiday in Euro and US? Most of the traffic is came from Euro and US. So, it really affect if that's long holidays happen.
from over here, my advise would be to quit worrying so much about how much your getting per click, and more about how much traffic and clicks your getting in general, 100 and some odd clicks for ALL of september?? Thats very very very low, even if ya got 10 dollars a click thats only 1000 bucks for the whole month.
seems september is good with me because i've made 15 with my new site it only 40 days, is a little baby for now (this is my first site, thanks Digital Points for what i've learn from here )
