Don't post the stats publicly, as its not allowed in adsense! Your stats are not good, apart from the fact that you got good traffic. Work on your ads placement and blending to have a decent ctr. You much be on a very low paying niche anyways, cheers!
Overall good. But you should have got more clicks. Keep it up. I dont believe your earnings will change with ad placement etc. Sometimes its high and sometimes its low..depends on niche. Thats all.
I think is better to have earning than nothing. You have already traffic then maximize with ads placement.
stats are good..CTR should be atleast 1% unless you run a forum or you get lot of repeat visitors. for a site with most of the search engine traffic, u should get atleast 2% ctr.
