If you are running Chitika Ads or planning to do so, one thing you should consider carefully is ad placement.
I am currently running Chitika ads across several of my blogs, including this one, testing the ad placement of each one in relation to Google Adsense ads. Finally, I found that the best way to display Chitika ads and Google Adsense together is by placing them just after the blog title, see screenshot below:

Improved conversion
I notice that there is an improvement in the click through rate of both ads by between 40-60 per cent compared to putting them as skyscraper banners in sidebars.
Chitika ads are special in that they only target search engine traffic from the United States, Canada as well as some selected countries. They won’t appear to normal blog visitors or those coming from countries other than the selected ones.
Those who come to this blog entry from this blog’s front page or from non-selected countries will only be able to see the Google Ads, because Chitika will be hidden, see screenshot below:

By the way, this is also one of the most effective ad placement for Adsense.
How did I manage to arrange these ads?
Quite easily. Both ads will be automatically inserted in all posts — past, present and future — thanks to a minor customisation I’ve done with the Thesis Wordpress theme, the one I’m currently using. Not sure if I can do the same with other Wordpress themes though.

Did not try Chitika before. How is the revenue compare to AdSense?
It’s about 30 per cent of adsense’s revenue at the moment. It used to be just around 5 per cent but that was before I changed the ad placement.
