I have a site where i dont want to show ads for US visitors and some other countrys, but i dont mind to show ads to others. Its ok, to code my site to show ads only for some visitors? question is, google receives clicks from my site, but if google goes to my site no ads are shown. Google and bots see a page with no ads.... no problems with that?
There's no problem with doing that as long as you don't modify the Adsense code in any way. You could put the Adsense code in some sort of include file and use server-side scripting to decide when to show it.
