Have you ever wondered what ads are showing in your AdSense, Chitika and YPN units around the world in different locations?
These advertising systems are all geographically targeted advertising systems (Chitika less so but they do to some extent). The ads you see in your part of the world can be quite different to those you see in mine.
AdSense does offer a preview tool but it only works in windows versions of IE. Chitika and YPN don’t offer such tools.
Digital Inspiration has a cool tool that might be useful for you.
The sandbox tool shows you what type of ads your site is likely to show in different geographic locations. It will also give you a comparison between the ads that the three different systems will serve to your sites in different color schemes to help you to choose what ad system might serve the most relevant ads to your blog.
I can’t vouch for the accuracy of it but it seems to work and might be useful for some. Let me know what you think.
