Block clicks from specific countries

How to block clicks from specific countries

[TuanLa1972]

Hi, all.
My site launchs today and I would like prevent me from being banned by blocking Ads clicks from specific countries (because of sensitive reasons :) ). Can anyone suggest some idea or some threads i have to read?
Thanks in advance.
Tuan.

A good start: [google.com...]

You may want to choose hiring a service instead of doing this on your own server. There's no 100% chance of blocking traffic but it should be expected to be powerful enough to cure your major pains. :)

I serve AdSens by SSI server side include.

I can filter by anything I wont.

But since nobody gets banned for Amazon ads to often clicked, it's a nice idea to replace for certain visitors the AdSense ad by an Amazon ad.

Otherwise, it would looke like there are 2 holes on my page.

So the ads are on their right place, only not from a PPC program.

Finally using PHP script I can block Ads for specific countries. My website shows the content without Adsense Ads for visitors from specified countries, for anothers shows content with Ads.I hope that it is not against Adsense TOS. Am i right?
Thanks.

i have once coded a PHP filtering script for ip filtering, but i am sure that is not 100% accurate.

I'm just going to test this in April 1. Based on GeoChannel. By the way you can install GeoIP product to display ADs to your selected countries.
