Podcasts can be an amazing marketing tool, giving you increased publicity and a built-in platform to advertise your products and services. Over the last decade or so, podcasts have grown from niche hobby to mainstream media channel. In line with this growth trajectory, superstar podcast creators have won big; Joe Rogan, for example, recently landed a $100-plus million deal to become exclusive to Spotify. And in the wake of increased consumer awareness, millions of people have flocked to the format to try and take advantage of it.
