I am confused!!!

Help, I need help.

For the past one month, I was earning average USD1 to USD2 per days but recently starting from May 15 my earning was dropped drastically, even zero amount. Is that means I was blocked by AdSense ? Many people say the less CTR rate would get better earning but why sometime I have very high CTR but earned much than the low CTR ? I am confused, can somebody please explain it to me ?

Thannk you very much.

AdSense

Hi, I am currently earning USD1 to USD2 per day by placing the AdSense advertisements in my blog. Can anyone share with me/us how to make more money from AdSense ??

Why not we form an alliance so that we can visit each other site to earn little money from blogging??

Thank you very much.
