Geo - Targeting

Geo targeting in geomarketing and internet marketing is the method of determining the geolocation (the physical location) of a website visitor and delivering different content to that visitor based on his or her location, such as country, region/state, city, metro code/zip code, organization, Internet Protocol (IP) address, ISP or other criteria.

The best way to really take advantage of this technology is through a company that is owns it's own prorietary software and is pushing it's listings all over the web. Localadlink is by far the best way to get your business in front of specific zip codes.
