A question I answered on Quora: How do you use your podcast for your business?

A:
Center the topics of the show on your area(s) of expertise.
Advertise your products and services on your show through mentioning them, through ad rolls, or both.
Interview the people you with whom you wish to do business.
If you’re a consultant or coach or therapist — something that can be administered via conversation — display your expertise by having a session or consult on the air.
Share your show with people who need the help/information/entertainment you’re offering.
