A few years ago, if a podcaster came to me and said, “What’s an effective call-to-action I can use to help grow my show?” I would reply, “Make sure to tell your audience to subscribe to your podcast on their podcast app or wherever they listen to podcasts.”
New listeners (and sometimes even our longtime listeners) need the reminder that if they like what they’re hearing, they’ll probably want to know when new episodes as they’re released.
