Some sites seem to customize their pages depending upon where they detect you are from (i.e. - U.S., Canada, UK, France, etc.).
How do they do that?
It would be nice to do something similar. My site is pretty simple, but I would like to avoid the risk of having a family member click on my AdSense ads and getting me kicked out of the program. So now I am wondering if there is some way to have a non-ad page served to my IP address, and a page with the ad on it served to everybody else. How would I go about doing this?
