What a trailer is for
Directories such as Apple Podcasts accept a trailer as a short episode that introduces the show. It also gives you something to share before the first full episode is ready.
What to include
Keep it to one idea: who the show is for and what they will hear.
- The promise: what a listener gains.
- Who hosts, in one sentence.
- A short sample of the voice or a guest.
- The release date or rhythm, if you know it.
- A single instruction on where to subscribe.
How long it should be
Thirty seconds to two minutes is common. Shorter is easier to share. Longer trailers lose the people who have not yet decided to listen.
How it is produced
The trailer is recorded and edited like an episode, with the same intro music and loudness. It is often the last piece produced, because it uses the best moments from the first episodes.
