In my second day of using adsense I made 32 cents is that good for a low impression site (total of 93 impressions in two days.)
The more important are: (a) your eCPM for these two days and (b) your CTR (click-through-ratio). Your current eCPM is about $3.20 which is not bad. If your CTR is more than 5%, I think your ad-placements are good.
Doesn't sound bad if it scales up too, I'd be making quite good money if I had a consistant eCPM like that.
I think you should look at your average earnings over a month or so , that will give you a better picture
Two days data is not sufficient to reach a conclusion. You stats will depend a lot on type of site you have , the source of traffic you have, quality of content etc. Dont bother about adsense for atleast a month. After sometime , once a pattern starts to develop, you will ,yourself, know whats working and whats not. For low traffic site it is better to compare weekly or maybe monthly data than daily data.
I will say look at your figures once a month goes by and then determine if it is good by your earnings and cpm. If you have a cpm between 2-5 that means it is pretty good. Stay working on to improve your content and keywords to stay with good earnings.
It is a good start. After all we cannot say more about a blog with low traffic. Try to improve the traffic count and check the adsense stats gain.
