I was listening to The Podcast Answer Man (PodcastAnswerMan.com) the other day. He made a great point. He described his audience as podcasters who are serious about the quality of their show and serious about turning their podcast into a business.
He admits that even though he has many hobbyists listening to the show on a regular basis, his show isn’t necessarily targeted toward them. His show is for the serious podcaster.
Your target audience for your show should be just as clearly defined.
