First things first- you heed to have high quality podcast content. Your listeners will come back if your information is helpful and/or entertaining. In order to have fresh content, you should consider ideas like having a co-host, interviewing experts on the topic, answering listeners questions, etc.

You might want to think about having a "teaser" to keep your listeners coming back. Think about TV shows and how they feature a clip from the next episode, often after the ending credits roll. This excerpt gives the audience a "teaser" on what is upcoming; their curiosity will keep them coming back for the next episode.

You might also think about your local radio station. They typically hold several contests throughout the year - you can apply this principle to your podcast. Try teaming up with other website owners who might be willing to help you promote your contest, or to donate prizes. During each podcast, give out a clue, such as a keyword or phrase- something they can use to help them to win the contest.

If you have your contest set to be discussed on four or more episodes, at the end of the concert, ask listeners to send in an email stating all four clues. The first three correct entries would be eligible to win your prize.

The easiest way to get your listeners to come back, is to involve them in each new show. They will be more dedicated if you can somehow make them feel as if they are a part of the show. Many hosts will give listeners a phone number on which they can call in, or record a promo message.

Your radio station may also use this tactic. They sometimes have their listeners record promos like "you're listening to xxwwnn 104.7" or something similar. The listeners feel connected and feel as though they have a bit of fame being on the show.

If your podcast isn't quite taking off as quick as you would like, keep working on developing quality content. Don't forget to keep marketing it. After some time, the time you put into it will pay off and you'll be enjoying a steady and loyal audience.
