GeoSwitch is a plugin that allows you to change the content of your site based on the location of your client’s IP.

This plugin creates a javascript widget in your sidebar that shows ads to your site visitors based on what country they're in.

Enable GPS lookup for the Geo Controller plugin and collect geodata from the mobile visitors.

This plugin uses the MaxMind GeoIP JS Web Service to return the Country, Region, City, Latitude, and Longitude WordPress shortcodes.
