Downloads: One of the most basic metrics for measuring the success of your podcast is the number of downloads. You can track the number of downloads for each episode using your podcast hosting platform or a tool like Chartable.
Listenership: It's also important to track your listenership over time. You can use analytics tools to track how many listeners are tuning in to each episode, where they are located, and how long they are listening.
Engagement: Engagement metrics, such as social media shares, comments, and ratings and reviews, can help you understand how your listeners are engaging with your podcast and whether they are finding value in your content.
Revenue: If you are monetizing your podcast, revenue metrics can help you understand the financial success of your podcast. You can track revenue from sponsorships, affiliate marketing, merchandise sales, and other sources.
Feedback: Finally, it's important to solicit feedback from your listeners to understand how they are responding to your podcast. You can ask for feedback through surveys, social media, or direct communication with your listeners.
