I'm going to create a Feed reader app. When a user requests a feed, the feed is downloaded (or loaded from cache) on my server, then it downloaded from my server to user's PC/smartphone.
But I think Google Feedburner won't know that, and won't show real Subscriber count for admins. Is that right?
What should I do if I want google to count readers (also who are using my app) correctly?
What your basically talking about is creating a web proxy for the feed, and then serving the proxied feed to your users. By default this method will not update the feedburner subscriber counts as they will only see 1 unique visitor requesting the feed, however there are methods to inform google that you are requesting the feed on behalf of a certain number of subscribers.
In the case of stand-alone feed readers, that user has an application running on their computer which fetches the feed repeatedly throughout the day. We look at characteristics of those requests, and differentiate between repeated requests from the same person (as indicated by regular polling intervals, consistent IP addresses, and common user agents) and different requests (where one or more of the previous data points vary). In the case of web-based feed readers (My Yahoo, Google Reader, Bloglines, Pageflakes, etc.), those services retrieve the feed repeatedly throughout the day, but do so on behalf of multiple people. Almost all of these services report to us how many of their users are subscribed to the feed. At the end of the day, we tally up how many stand-alone feed readers are subscribed, and add them to the web-based users. The end result is the total subscriber number we report. (I’m leaving a few details out; see below for a more complete answer.)
