Geolocation refers to the identification of the geographic location of a user or computing device via a variety of data collection mechanisms. Typically, most geolocation services use network routing addresses or internal GPS devices to determine this location. Geolocation is a device-specific API.

The Geolocation API returns a location and accuracy radius based on information about cell towers and WiFi nodes that the mobile client can detect.
The business benefits of geolocation are far-reaching and are being leveraged by all types of enterprises—manufacturing, retail, financial services, insurance, transportation, utilities and governments. As business and government services are enhanced, the user or consumer of those services benefits as well.
Most of the sales teams are en-cashing the benefits of location-based marketing to convert both offline and online traffic into long-term customers.
Location-based marketing effectively diminished the sales barriers. The companies can now know how the people around them can be attracted to have a business with them.
Geo location is among the most advanced tracking technologies used to correctly determine or estimate a geographic location of an object such as a smart phone or a network-operated computer. This technology closely relates to other positioning systems but with added benefits that can favour business, trade and field work of the sales team. Geo location effectively uses latitude and longitude coordinates to map a meaningful location. Geo location services use either the IP address of a connected device or RFID tag for accurate address mapping.
Apart from providing an extra edge with the search engine rankings, the location-based services also provide detailed analysis of the location-based marketing technique.
