Growth & Marketing
Growing Your Podcast Audience
Podcast SEO, cross-promotion, repurposing, and the marketing tactics that actually move downloads — not the ones that look good on Twitter.
Great shows don’t grow by accident — they get found, and they get shared. Our flagship podcast marketing guide is the complete playbook; the guides here go deeper on the tactics that actually move downloads versus the ones that just feel productive.
Growth starts with being discoverable. Podcast SEO and our deeper dive on SEO for podcasts help the right listeners find you in search, while repurposing your content turns one episode into a week of posts. New to all this? Start with how to promote a podcast episode.
Then meet listeners where they already scroll. Our playbooks for social media, Instagram, and TikTok cover what works on each platform, and email marketing keeps the audience you’ve already earned.
Marketing pairs naturally with monetization as your audience grows, and builds on the distribution foundation underneath it. Castos Campaigns helps you turn casual listeners into subscribers with promotional tools built right into your host.
