You can’t, but fortunately it doesn’t matter! Although it’s possible to roughly estimate a so-called “subscriber count”, the number of people who are polling your RSS Feed is constantly in flux and does not accurately represent a true listener count. So rather than provide our customers with highly inaccurate data, Fireside provides Unique Download Counts for every episode. This is the same data that advertisers will ask for, as they understand that “subscriber counts” are meaningless when it comes to measuring a podcast audience. Unique Downloads are all that matters.
