When we display your geo-targeted ads, keep in mind that we may identify geographic interest based on the words in relevant search queries and the physical location from which those search queries originated. Physical location can be determined by the computer's Internet Protocol (IP) address, which is assigned by a user's Internet Service Provider (ISP). You might not see your ad if we're unable to determine that location. For example, this might happen if:

• The computer from which the search query originated uses an ISP that employs a proxy server, preventing us from identifying the computer's IP address
• The search query does not contain a recognizable location-specific term.

Here's what you can do so others see your Ad

If we can't determine the location interest or physical location from which a search query originated, we may display ads targeted to the entire market. To reach potential customers who might not be physically located in your targeted geographic area, consider creating an additional geo-targeted campaign similar to your regionally targeted one—except with region-specific terms in your keywords and ads.
