#39: Podcast Growth Strategy: Levers That Actually Work

Ed Barker, founder of Studio 1878, explains that podcast growth rarely comes from simply promoting more; audio podcasts typically grow slowly through compounding because discovery is inefficient and listening requires a major time commitment. The episode outlines key growth levers: guest networks (making it easy and valuable for interview guests to share), content velocity and consistency (weekly is often best, but consistency matters most), platform algorithms (especially Spotify and YouTube metrics like completion rate, follows, saves, streaks, watch time, and click-through), and audience sharing, which is high-friction and works better with specific “shareable moments” and targeted prompts. There's a note on podcast swaps and host personal brand (notably on LinkedIn for B2B) as underused channels, and clarifies that paid promotion works best when promoting specific high-value episodes to specific audiences as an accelerant.
