Top Podcast Tracking Services by Episode Share (April 2023)

This is an archived version, the current version is here.

Now that we have a good idea of which podcast hosts are producing new podcast episodes, let’s turn our attention to third-party podcast analytics services.

These services are typically provided by a company that is not the podcast host, but can provide tracking and analytics by being specified as the underlying media file url, which then redirects back to the host. Sometimes, these services are implemented as custom prefixes (taking the original media url and adding a prefix to it), but not always.

By intercepting every episode media file request, these analytics services can provide a view that is potentially larger than what the underlying podcast host analytics can provide.

Podtrac, one of the most popular services, released some interesting data about their US download figures for September 2021.

But how representative of the entire podcast world is this data? How many podcasters use services like these?

We already did the work of analyzing every single new podcast episode published (about 1.7 million in April 2023), identifying which podcast hosting company it belongs to.

We used the actual media file url (past any tracking redirects) to identify the host instead of the feed url domain, which can often undercount hosts that offer custom domains.

Let’s now take a look at the tracking services themselves. Of the new episodes that were published in April, how many of them included one or more of these tracking services? Some episodes had as many as eight of these redirecting trackers!

Note we can only observe “client-side” trackers. There are other podcast analytics services such as Triton Digital that receive private request logs directly from partner hosts. Like first-party podcast host analytics, the reach of these services is not measurable in a public way, and thus not included in this analysis.

First, a quick chart of the top podcast tracking services over time, based on share of new episodes every month.
