A question I answered on Quora: What can we do to best promote our educational Podcast's Patreon page www.patreon.com/thesocialexchange?

A:

Place a pre roll or post roll ad (maybe both) explaining your Patreon page’s existence to your audience. Have it as part of every episode.
Do an entire episode about the Patreon page — why it exists, what it’ll do for the show, what supporters get for being involved.
Link in the show notes for every episode and on the show’s homepage (website).
Send an email to your list sharing The who-what-when-where-why-how.
Promote in your other social media, youtube and snap/IG stories.
Have a great offer on each Tier of your Patreon that entices patrons. People are driven by self-interest.
