Know your audience: Ensure that you understand the demographics of your audience – who are they? what age ground and gender do they fit into? What are their interests? If you understand your audience, you’ll be able to provide them with better content.
Know your guests: Before you invite guests onto your podcast, do your due diligence and research them thoroughly first. Simple things such as mispronouncing your guest’s name can not only make you seem incompetent but may also offend your guest.
Length: A good podcast should not be too long. The longer the podcast, the less likely that people will listen to the entire thing. That doesn’t mean that you should make them to short either. A podcast that lasts for 15-30 minutes is considered to be ideal.
