It there a way to count unique users that download podcast from itunes?

I created a podcast, and set it up in itunes. I am able to track the number of downloads for the media files, and I would like to know how many different users are downloading the files. I tried using cookies / sessions, but that doesn't seem to work. Itunes ignores cookies, and thus a new session id is created every download. 开发者_C百科

Is there another way to track unique itunes users of my podcast?

I don't know if you are still interested, but Blubrry offers free stats. It tells you how many people are downloading from iTunes and any other platform. This is much easier than trying to devise your own system, and is high quality.

Cookies wouldn't work because if their cookies were cleared then it would count as a new user. The only "unique" thing about users are there IP addresses really. Since they're "downloading" it if two people use the same computer the chances of them both needing to download it are slim, so IP address would work decently well.

This isn't fool-proof but if you're just using this to get track stuff for yourself, it might be good enough.

I use FeedBurner to track subscribers and downloads of my podcast. Gives a lot of great stats.
