If you think that adsense is the end of world for your blog/website for your earning , you are totally wrong. There is something other than adsense which is more reliable, more easy and more profitable.
Yes Bidvertiser is another money earning tool which you can add to your site.
Nice thing is that it pays you after you earn only 20$ as compared to adsense's 100$.
Another advantage is that money is directly transferred to PAYPAL.

Now place BIDVERTISER ads with ADSENSE ads and earn more.
