Noted book author and marketing expert Seth Godin wrote a post recently, Advice for Authors part 1 and 2. If you are an aspiring book author it is certainly a post worth reading.
He writes, “Blog mentions, on the other hand, matter a lot.”
He does not mention podcasts. I am not sure how much podcasts matter for authors and book sales. I can tell you that Amazon affiliate sales (through my links) of books by authors interviewed on this podcast are low. For most books my affiliate sales are probably in the single digits. A few titles have achieved low double digit sales. What I don’t know is how often a podcast plants a seed for later mention.
If you are an author do podcast appearances matter? Have they helped your sales?
If you are a podcast listener does hearing an author on this or other podcasts influence your purchasing decision?
The market for books by paramedics and EMTs is a micro niche. Maybe 10 books sold through a podcast for this niche is significant. I am not sure.
If you are looking for book ideas I added an Amazon book store recently, EMS Books for your Kindle.
