While marketers can appear as guests on just about anything (shows, webinars, blogs), the most prevalent method is podcast guesting.
Podcast guesting is appearing as a guest on someone else’s podcast. You can spend anywhere for 15 to 50 minutes sharing your perspective on something, a story of value, or marketing experiences to the podcast’s audience.
In return for guesting, you have the opportunity to reach an audience and generate more influence, income, or followers for yourself.
