Creating added value for your podcast subscribers is a great way to raise or boost your profile.
One way to do this is to create a PDF or digital book made up of the key points of your podcasts, collated show notes, or with extra information that will be of interest to your subscribers.
You can keep it simple with a small PDF of a few thousand words that you give away to new subscribers to your mailing list, give it away as a free-be to all, or go further and write a far more in-depth book that can be sold via print-on-demand sites such as IngramSpark - and offered as both a digital and hard copy publication worldwide.
If you enjoy writing then producing these PDF documents can be great fun, if not ask someone to help you write and design it.
As an example, here is my Podcasting Made Easy cheat sheet, normally reserved for subscribers to my mailing list but made available here for a short time by way of illustration.
As always, if you have any questions about podcasting then do let me know.
