What does "OUT" mean on the chart rankings?
If you see "OUT" as your rank, it means your podcast or episode has recently fallen off the chart. If and when your podcast reappears on the charts, you'll see its new rank.
Please note that ranks change often, so don't be discouraged! In particular, the Apple Podcasts show charts are based on recent subscriptions, so they change very frequently based on the amount of new subscribers.
