A google adense secret revealed

[mora]

Hello,
Wanted to share this with everybody,

The top-paying ads will be shown in the ad unit that appears first in your HTML code. To take advantage of this, you will need to understand which of your ad units has the highest clickthrough rate (CTR) by using custom channels. Then, you can easily change the code of your website to make sure that your top performing unit is the one with the highest-bidding ads.
