When I promo my podcasts, we do it with video clips, that a editor manually chooses

We tend to get 3 or 4 good 1 min clips from a 1 hour conversation

Generally that is the best way to “trial” a long form podcast

People who want to learn more will then listen in full

I’ve also seen 10 mins clips be successful. If you have 2 to 3 hour convo you can pull a number of good sections out

Initially you could build it so someone manually enters their clips, with the link to the main show

One day the client could assist with the production work (which for sure people pay with)

Ie - you give exposure and sell implementation
