Choosing a Podcast Niche: A Data-Informed Framework

The best niches combine audience demand, sustainable sponsor economics and your unfair advantage. Here's how to find yours.

The landscape

When it comes to why 'pick a niche' is really three decisions in disguise, the details matter. Here's what the evidence and practitioner experience point to:

• Broad niches (tech, business, health) have the largest audiences but the weakest differentiation; sub-niches (AI regulation for fintech founders) convert faster.
• Check CPM benchmarks before committing: business and finance shows command $45–$100 CPM while entertainment averages closer to $18–$40 — same effort, very different economics.

What actually works

When it comes to why 'pick a niche' is really three decisions in disguise, the details matter. Here's what the evidence and practitioner experience point to:

• Competition analysis: search your target keywords in Apple Podcasts — if the top 10 results all launched pre-2022 with stale feeds, demand has outgrown supply.
• The '50-episode test': could you generate 50 distinct episode ideas in this niche in an hour? If not, the niche is too narrow or too shallow.

Putting it into practice

When it comes to why 'pick a niche' is really three decisions in disguise, the details matter. Here's what the evidence and practitioner experience point to:

• Your unfair advantage can be access, expertise, taste or simply consistency — but it must be identifiable before launch.
• AI-assisted production changes the calculus: research-heavy niches (history, science, finance) become viable for solo creators because the research pipeline compresses.

Key takeaways
