Launching a Podcast

How to Start a Podcast

Your first-episode launch plan — from idea to live in Apple Podcasts, Spotify, and every other directory listeners use.

How to start a podcast — Castos guide

Starting a podcast comes down to a sequence most people never see laid out in order — and that’s exactly what this hub provides. If you want the whole launch in one place, start with our flagship guide, How to Start a Podcast, which walks the entire process from first idea to live episode. The guides below go deeper on each step along the way.

Get the fundamentals right before you record. How podcasting actually works explains the RSS-and-hosting plumbing behind every show; defining your ideal listener is the audience-first exercise that shapes every decision that follows; and the complete podcast launch guide is the top-to-bottom checklist you can work straight through. Don’t have a following yet? How to start a podcast without an audience is the playbook that works anyway.

Each stage of a launch also has its own deep hub to lean on as you reach it: planning your format and angle, choosing equipment, recording clean audio, and publishing and distributing to Apple Podcasts, Spotify, and YouTube.

When it’s finally time to press record, a couple of how-tos make episode one far less daunting — chief among them recording your first podcast and becoming a better podcast host.

Every show you publish needs a host to store its files and generate the RSS feed that the directories subscribe to. Castos handles that hosting and one-click distribution — and you can start a free trial whenever you’re ready to put your show online.

Frequently Asked Questions

How much does it cost to start a podcast?
Most new podcasters can launch for under $150 — a dynamic USB mic (~$70), a hosting plan ($19/mo at Castos), and free editing software like Audacity. You can spend more on gear later, but expensive microphones do not make new podcasts succeed.
How long should my first podcast episode be?
Aim for 20–35 minutes. Long enough to deliver real value, short enough that you can finish editing and publishing without burning out. You can always extend episode length once you have a workflow that fits.
Do I need a podcast host to publish my show?
Yes — a podcast host stores your audio files and generates the RSS feed that Apple Podcasts, Spotify, and other apps subscribe to. You cannot publish a podcast from YouTube or a website alone.
What's the difference between a podcast and a video podcast?
A traditional podcast is audio-only, distributed via RSS. A video podcast adds a camera and typically publishes to YouTube alongside the audio RSS feed. Many shows now do both from one recording.
How often should I publish new episodes?
Weekly is the sweet spot for most new shows — frequent enough to build a habit with listeners, sustainable enough to keep up for a year. Consistency matters more than frequency; pick a cadence you can hold.
