After a year, I finally going to receive my first payment from Adsense!
All this while I did not really bother much about Adsense placement until this month, I started giving it more attention; putting Adsense code in each post. That really makes a lot of difference.
Instead of getting only a few dollar a month, I got almost $40 this month! That really motivates me to start a few more niche blogs and see whether I can depend on Adsense for my monthly income instead of writing paid post which will jeopardize the blog page rank.
