Increase Revenue by 25% with Chitika

I receive an email from Chitika telling me how the guys over at Zedomax.com recently increased their overall advertising revenue by 25% by adding Chitika | Premium to their site. Man, 25% increase in revenue is quite a lot. Well, at least in my case. They manage to increase their earnings by just adding a Chitika | Premium unit above their article titles, thus keeping their AdSense units right below the titles. It has been a while since I last login to my Chitika account. Perhaps I should give it another try and see how it goes again for me.
