After you have identified new podcast formats from your benchmarking data, you need to test and refine them. This means experimenting with different elements of your podcast content, such as length, frequency, format, tone, topics, guests, production quality, and promotion strategies, and measuring their impact on your KPIs. You should use various methods and tools to test and refine your new podcast formats, such as surveys, interviews, focus groups, A/B testing, and analytics. You should also solicit and incorporate feedback from your audience, and monitor and adapt to their changing needs, preferences, and behaviors. For example, you might test different lengths of episodes, such as 15 minutes, 30 minutes, or 45 minutes, and see how they affect your podcast downloads, retention, and engagement. You might also try different formats of episodes, such as interviews, case studies, or tips, and see how they resonate with your audience.
