I stumbled upon a friend’s Facebook discussion board and one topic there is about how to improve Google Adsense CTR?

To those who dont know what is CTR in  google adsense is, let me share it here because some of you may find it useful.

What is CTR and how do I read it?

CTR stands for clickthrough rate, and in the simplest form, it is the number of clicks an ad receives divided by the number of times the ad, ad unit, or page is viewed. In other words, it is the percentage of how many clicks an ad received (based on how many views it received).

Therefore, the higher the CTR is, the better the performance is (ie: a larger number of clicks an ad/ad unit receives).
