Here are three keys to podcast growth: Interview top people in your field (get the right guests). Two, get featured on iTunes (not just listed but featured on their front page). Three, encourage your guests to share their interviews via their blogs and social networks.
Once you create a podcast, you need to get the word out so people can find what you have to offer.
