What determines my podcast's ranking on the charts?
Each podcast player has its own way of determining charts, and while none have revealed their exact algorithm, we can dive into what we know about them.
To quote James Cridland from Podnews in a great article about podcast stats:
While Apple do not publish the way they compile the Apple Podcast charts, they are generally understood to be based on recent subscriptions. An appearance on the Apple Podcast charts reflects a podcast’s ability to attract a larger number of new subscriptions to their podcast over recent days. It is not related to downloads.
You can appear very highly on the Apple Podcast charts by planning all activity around your podcast release on one specific day, and encouraging as many subscriptions on that one day as possible.
We'd add that while the show-level charts are based on recent subscriptions, the episode charts seem to be based on downloads and/or listens. That is, episodes that rank highly on, for example, the US podcast episode chart seem to really be the most popular episodes.
Spotify's charts seem directly related to listens/popularity. Spotify doesn't currently offer episode-level charts.
Every week, we use Chartable's IAB V2-certified measurement of audience size to create the Top 200 and Trending charts across twenty different countries, based on weekly changes in audience among the 5,000 podcasts using our proprietary feed integration.
