As part of my experiment I discussed in my last post. Due to dramatic decrease of my Adsense income, I even get into chance of trying some advertising networks like Adbrite and Bidvertiser but the things is other networks payment is not that big as Google adsense though it was bid enough to compensate to your loses. So since my experiment was not that long enough to get conclusion I still try to learn more about Google Adsense Optimization, a lot of books available about this and of course a lot of this was available in the net, that is why I come out of my own Top Ten Google Adsense Optimization, the credit was to all site who posted their expertise in optimizing Adsense for free. BTW I need Four more to complete my top ten list.
