Selecting a podcast topic that has an existing niche fan base will increase the number of people who listen to your show. Identify a niche that you're familiar with within a larger community to determine what your podcast should be about. Podcast topics can include politics, social issues, wellness tips, music, celebrity rumors, or interesting stories. Poor audio quality will turn new listeners off and lower the chances of your Soundcloud going viral. Make sure that you use high-quality microphones and recording equipment so that people can understand the podcast. Popular podcasting microphones include the Heil PR-40, Samson Meteor, and the Blue Microphones from Yeti. If it's more than just one person, having dynamic, interesting, controversial, or funny hosts will increase the popularity of your podcast. Make sure to get hosts that have varying opinions and views to keep the podcast interesting and to encourage lively debate. The guests that you invite onto your podcast will influence your fans and audience. Get guests that fit within the scope of your podcast and invite people who have a large fan following. Even if people don't know your podcast, the interview may go viral.
Choose an interesting podcast topic. Use the proper audio equipment. Develop dynamic host chemistry. Secure interesting and compelling interviews.
