Does no. of page impression also lead to earning?? or is it the clicks which are the only way to earn from adsense.Thanks
Adsense also pays for the impressions. $0.01 to 0.05 per 1000 impressions, very low..... isn't it? So, clicks only can earn more money from adsense.
Some of the ads are CPM (pay $0.25 per thousand impressions for example). I would suggest you to focus on getting more clicks. Impressions won't earn anything.
You can get some earnings from impressions only, but it is so low, that you should not bother abot that...
