Checkout the source of traffic to your website thru Google Analytics. If your website is getting maximum traffic from Social Bookmarking sites like Digg, Stumbleupon , then Google will not give you much amount for Ads click.
i am getting my 95% of the traffic only from google and not from other search engines ,, my entire traffic is organic , and only 5% of the people come directly or from social bookmarking sites like orkut and others
Can you share geo ratio of your traffic . If you are receiving traffic from Asian countries then your earnings are normal buddy . In tech niche we compare our earnings with 10 cents per click and if you have got 26 clicks then you must earn $2.6 but you have earned more then that which is fine right now .
My traffic is from India, US and from the other European and American countries i don't know how to check the percentage of the traffic,
don't feel bad. it may be happened due to some kind of interst based ads. in my view your are earning a good money but as you are saying you have spend a lot of time, it hearts. hope nest time you ll feel better.
you can't measure from page impression, but from visitors, how many visitors come to your blog anyway?
May be you are not using the right keywords which pay you more.. And if you really wanna earn then most of your traffic should be from US. - Digital -
i am from India , here i will get Indian traffic in the morning and i am getting US , UK and Canadian traffic in the night , still there is no difference
Traffic comes from US/UK might get a higher click revenue, and you also can use the keyword research tool for choosing better keywords.
Adsense earning is like an online auction, the earning per click depends on visitor language,demographic,website content(keywords). 0.01 is the min click be happy its not less
