I have been blogging on tech related stuff for almost an year now and really make very less money. To earn more I made a site on 'college debt consolidation' just to see how it fares. It's not even finished yet and I feel it's much more rewarding. My tech site: 454 page impressions, 1 click = $0.31 My test site having the high keyword: 6 page impressions, 1 click = $0.62. That's exactly twice the amount I earn from my tech site with only 1/75 th of the traffic! The point of this post is to request Google/advertisers to increase the value of ads in tech related sites so those of us who are looking to make some decent amount from adsense don't have to resort to building sites on which we have no expertise.
