Problems with GeotargettingAd Butler uses one of the most accurate Geotargetting databases currently available, and updates that database regularily. However, because of the nature of IP assignment it is not always possible to identify the location of an IP.
The targetting database is very accurate at correctly identifying the locations of IPs that it recognises, but when an IP can't be recognised it excludes it from geotargetting to prevent any ads from being shown in error.
Generally IPs that belong to large, multinational ISPs or corporations that assign IPs on the fly fall into this category.
If you are using such an IP, you may not be able to see your targetted ad, but the ad will be shown to any users that can be certified as being from the target region.
