16% CTR ... mmm kind of high for my taste.... about the 2 cents clicks.. seems just a low paying niche...
I'll also add that the $.02/click wouldn't rank right at the top of my list. Don't forget that's just an average. However, it's money you didn't have yesterday, and if you can maintain that level, it's going to pay for hosting and some pizzas and beers. You'll need to either filter out the low payers or make a concentrated effort to up the quality of your site. Better quality will usually equate to higher paying clicks.
I would be happy with the clicks but very very disappointed with the earnings from them although something is better than nothing.
For some reason you are attracting low pay out ads. Maybe because of the niche you are in and maybe because of poor targetting The other explanation is a lot of those clicks may be registered as invalid clicks hence no income generated
Were you previously earning more with the same clicks? If so you may have been smartpriced meaning you need to change your writing and niche up a little if you want to make more.
I think it is too low. think about a way of improving. I am also new in adsense and blogging still I can earn at least 1$ from 20 clicks. Page impressions are not also not high.
