Podcasting is a compounding game — the curve is flat for a long time, then it bends. Shows that quit at month 6 never get to see the bend. What is podcast SEO? Podcast SEO is optimizing your show title, episode titles, show notes, and transcripts so they rank in Google, Apple Podcasts, and Spotify search. Strong podcast SEO can drive 30–50% of new downloads for an established show. Should I use paid ads to promote my podcast? Rarely. Paid ads work for podcasts at scale (50K+ downloads per episode) where the ROI on a $10 CPM makes sense. For new shows, spend the time on SEO, repurposing, and guesting on other podcasts in your niche. How do I get more podcast reviews? Ask. At the end of every episode, ask listeners to rate the show on their favourite app. Reviews are the social proof that converts directory browsers into subscribers, and they help your show surface in algorithmic recommendations. What is the best way to repurpose podcast content? Pull 30–60 second clips for short-form video (Instagram Reels, TikTok, YouTube Shorts), turn key insights into LinkedIn posts and Twitter threads, and convert long episodes into blog articles. Each episode should produce 5–10 secondary pieces of content. ## Related Hubs Where to go next on the growth journey.
