When a podcast application downloads a podcast episode, it sends the listener's IP address to the podcast host server. These IP addresses are logged by the server, and can be used to look up a geographic location for mapping purposes.
PodOmatic stats also can track the number of page views, feed views, unique visitors and subscribers to podcasts. PodOmatic's system provides a breakdown of downloads by podcast client, unique visits to a podcaster's web page and charts of activity over time.
A working example of the stats system is available at the PodOmatic site.
PodOmatic, a podcasting service provider, has introduced a "Geo-IP" statistical tracking system for podcasters. The system lets podcasters map IP-based geographic locations for their podcast listeners.
