A particular set of sites of mine which discusses health insurance and credit gets about 10,000 impressions a day. With a good CTR of 1-2% what can i expect to generate in adsense commissions from this?
10000 impressions........ may be something about 20-25$ and if there are clicks also then you can earn a lot.
If the 10k impression is largely based on returning visitors (discussion area of the site), then your earnings will definitely be significantly lower.
Impression doesn't mean you'll get good income, It's depend on many factors like which kind of visitors are coming on your website.
It depends, impressions are nothing, if your ads are terribly placed, keep experimenting, it will come in time.
