I had seen Comm’s book What Google Never Told You About Making Money With AdSense mentioned on a website using my CNNesque theme. I went to the page and found it cost $97. For an eBook! Ouch! A bit steep. But I started reading reviews and found the reviews were all pretty good. I am not a beginner with Adsense, but I am sure the book will have some stuff that will help me improve my click throughs. I have lots of traffic, and I am sure I can be making more money than what I am making now. I found a link through which I bought the book for $57. If I can boost my AdSense earnings, it will be worth it!
