A change to the way Apple’s iOS operating system manages automatic podcast downloads may impact a key performance indicator for advertisers.

For years, Apple Podcasts automatically paused episode downloads when a follower’s device storage was full or when she hadn’t played any of the last five episodes for more than 15 days. Then, when the follower (i.e., subscriber) resumed, Apple would download all unplayed episodes.

On the other hand, the download metric is less meaningful for performance advertisers — those looking for specific outcomes, such as signups or sales. Even with iOS 17, some (or even many) downloaded episodes are not listened to. Say a podcast is…
