Yes it absolutely depends on your niche. I earn about $1 per click on average, but am looking to increase that. Would you mind sharing a bit about your site's topic? Is it the sites in your sig? Thanks.
Oh please tell to us what was your strategy? Was it just a lucky or did you optimize your site content according to the results of Google Keyword Selector?
Yesterday i had 18 clicks got only 3.22$
YOU ARE LUCKY!! congrats
Even $3.22 from 18 clicks are good one. People who have celebrity based website got $0.18 from 18 clicks. But yeah they got huge traffic and I think their traffic compensate them.
My daily adsense earning is 5-6$.... although i am not working on daily basis... i have education blogs of Ignou University, oxford university... getting daily good visitors and earnings too.... Secondly, i have launched 2 new blogs on new thing and started earning from that so may be i'll reach daily 10$ earning soon....
