Why growing a podcast audience seems difficult

• Podcasts are traditionally only audio. It is essential to grab your listener's attention immediately.
• Audio is not as easy to share as text or video.
• Discovering podcasts is a slower process and based on word-of-mouth recommendations and personal tastes.

It means you have to be strategic about how you get your show heard. Having guests on your show can help with exposure as they will share your podcast with their audience.
