There's a question I get asked a lot, maybe more than any other question related to podcasting except, “Is the blue snowball mic ok?” No, it's not. The question is, “My podcast isn't getting any traction. How long should I expect to wait before I start getting feedback? Should I quit if no one cares?”
If your podcast isn't getting any traction or getting new listeners, I would take a long, hard look at a four things:
How good is your content?
Are you engaging with your audience?
How good is your audio quality and delivery?
Are you writing enough for your podcast episodes?
I don't think “How can I get more downloads?" is quite the right question. The question you should be asking yourself is, “How can I make my show better and more valuable for the audience I do have?” So that's what I'm going to share with you in this episode.
