Switching Ads using a javascript for Geotargeting?

Ok, I have both Adsense and Yahoo. For USA clicks, I'd like to use Yahoo (they bring me way more money). For international, I'd like to use Adsense (Yahoo doesn't allow non-USA clicks). I want some way to detect the users IP address and then switch the Ads on my site dynamically based on their location... so either Yahoo (USA) or Adsense (International).

Does anyone have any ideas or examples on how to do this? I am sure it has been done before.

Thanks,

Ethan

 

why do you want to do it with javascript specifically? it'd be completely transparant with php

 

PHP is fine with me as well. Do you have an example I can see?

 

google for some ip2country php script, this one for example: http://www.scriptsez.net/index.php?action=details&cat=Miscellaneous&id=1087484351 (I haven't tested it, just found it on google)

 

Thanks for the link Pozer. Will look at it.

Is it OK under TOS?

 

GeoTargeting is certainly ok with the TOS, in fact, YPN recommends you do it. There are many scripts that out that can do it for you, such as phpadsnew or mySimpleAds.

Not only does it save your YPN account from being banned for too much international traffic, but it also makes you more money, since you won't lose the international YPN clicks, but instead you monetize them through AdSense clicks - Win-Win...

mySimpleAds is just awesome. thanks! I might get 50% more $ because of this!

 

The Geotargeting on this just isn't working well for some reason... is there a trick to it?
