Podcasts exist across various platforms and websites, meaning it is difficult to track podcast growth and the number of listeners following a specific show. However, there are methods to find out the number of listeners. The easiest way to see how many listeners a podcast has is to check out podcast download numbers and the number of subscribers. This is possible for podcasts that are hosted on platforms such as Spotify, Google Play, iTunes, SoundCloud, and others. To estimate the number of listeners, you can use a Web analytic tool. Every podcast-hosting platform provides tools for tracking subscribers by IP address and device. In this way, they offer specific data on podcast listenership. For example, iTunes podcast analytics provide podcasters with information about how often users listen to shows and episodes and how the popularity of each episode changes over time.
