Well, let's face the fact. Most Google adsense publishers are not able to earn a decent income from their adsense.
However some changes to how you implement adsense to your site may have a drastic change on your website revenues.
Implement adsense at a position where it can be seen easily. We often ignore how our website is seen by visitors. if your adsense ads cannot be noticed easily, they will not be clicked on.
Merge your google adsense background and border color, with that of your website. Often it is what Google calls "ad blindness". If something looks like an ad, people avoid looking at it. Your adsense should merger with the content of your website.
Finally, check your content keywords. The adsense ads displayed are relevent to the content of the website. If your website contents target ads that have low paying ads, then the revenue is less, even if there are lots of clicks. That is how a single click may pay you $0.03 or $20.00 . Targeting adsense ads that pay more increases website revenues substantially.

Top paying adsense keywords
The great CPC mistake: Now, this much implemented, it depends how we analyse good paying adsense keywords. CPC (cost per click) available on Google adsense is not enough, as the real payment depends on several factors. The bottom line is if there are enough advertisers who are bidding high on a keyword, then the payment of the keyword be good. A high CPC does not necessarily mean that there are enough advertisers who are bidding high on that keyword. Good earnings also mean that there are enough advertisers bidding high on that keyword.
