How to choose a podcast hosting platform
Your host owns your RSS feed, stores your audio and shapes your analytics. Rather than ranking products that change every quarter, here are the axes they differ on, so you can evaluate any of them yourself.

Choosing a host is a consequential decision, and most comparison articles answer it badly — by ranking six products against a snapshot of their current plans. Plans change; the underlying axes do not. This guide is about the axes.
To be explicit about what this is: it is a framework for reading a hosting platform's own documentation, not a review. No hosting platform is ranked here and none was trialled for this article. Where a decision depends on current commercial terms, the honest answer is to read the vendor's current pricing and terms pages before committing, because anything written here about them would be out of date before you read it.
What a podcast host actually does
Strip away the marketing and a podcast host performs four jobs:
- It stores your audio and serves it over a URL that podcast apps can fetch.
- It generates your RSS feed — the single document that every directory and app reads to discover your episodes.
- It counts downloads and reports them back to you.
- It submits your feed to the major directories, or gives you the feed URL to submit yourself.
Everything else — websites, players, transcription, ad marketplaces, video, communities — is an add-on. Useful add-ons, sometimes decisive ones, but the four jobs above are what you cannot do without.
The storage model is the first real difference
Hosts express their limits in at least three incompatible shapes, and which shape suits you depends entirely on the show you make:
| Limit shape | What it caps | Suits | Watch out for |
|---|---|---|---|
| Upload hours | New audio you may add in a billing period | Regular shows with predictable episode lengths | Bulk-importing a back catalogue can exceed the allowance immediately |
| Total storage | Everything you have ever uploaded, cumulatively | Short-run or limited-series shows | The cap tightens permanently as the archive grows |
| Downloads | How often listeners fetch your episodes | Long back catalogues with modest audiences | A single viral episode can push you into a higher tier unexpectedly |
Two follow-up questions matter more than the headline number. First: what happens to episodes older than the retention window on an entry-level plan — do they stay online, or are they removed? Second: if you stop paying or downgrade, what becomes of the archive? Hosts answer both differently, the answers change, and both answers live in the terms of service rather than the feature grid. Read them.
Distribution and feed ownership
Distribution is mostly a convenience feature: a host submits your feed to the major directories, or hands you the feed URL and lets you submit it. Either way the directories are pulling from one RSS document.
What genuinely differs is portability. Ask whether you can set a permanent redirect on the feed when you leave, and whether you can point a domain you own at it. A host that supports both makes migration a routine operation; one that supports neither makes your subscriber list its property rather than yours. This is the single question most worth asking before you upload episode one, and it costs nothing to ask.
Analytics: what "certified" means and what it does not
Download counting is less obvious than it sounds — partial fetches, range requests, bots and repeated app polling all have to be handled consistently, or two hosts will report different numbers for identical traffic. The IAB technical guidelines exist to make those numbers comparable between publishers, which is why advertisers ask whether a host's measurement is certified against them.
If you never intend to sell advertising, certification matters far less than clarity. Look instead at whether you can see per-episode trends over time, listener geography, and which apps your audience actually uses — that last one tells you which platform's presentation to optimise for. Some hosts also report platform-native streaming metrics that are not comparable with downloads at all; treat those as a separate number, not a bigger one.
Audio format requirements for podcast hosting
Whichever host you choose, the upload question is the same, and it is one of the few parts of this decision that is genuinely stable.
Hosts overwhelmingly accept MP3, and many also accept M4A (AAC). Around 128 kbps mono for speech, or roughly 192–256 kbps stereo where an episode carries music, is the widely recommended range — but your host publishes its own guidance and its own maximum file size, and that guidance is what you should follow.
The part that is not negotiable is where the MP3 comes from. Do not record to a lossy format: compression at capture discards audio permanently, before you have made a single edit, and every subsequent processing step operates on the reconstruction rather than the recording. Record and edit in WAV, export one full-quality master, and encode the publication MP3 from that master. Compress once, at the end.
The same rule applies to material you did not record. If a guest, a producer or an archive sends you an MP3 and you need it in a session, converting it to WAV first gives your editor a plain PCM source and stops the file being decoded repeatedly — it does not recover anything the original encode removed, and no tool can. For the full stage-by-stage breakdown see audio formats for podcasters; for the underlying comparison, MP3 vs FLAC vs WAV; and if you are preparing a back catalogue for import, batch conversion covers doing it in bulk.
How to decide
Work through it in this order, and the shortlist tends to make itself:
- Feed portability first. Check for a permanent redirect on exit and custom-domain support. If a host fails here, its other features may not offset the cost of being locked in.
- Match the limit shape to your show. Long back catalogue, small audience? Download-based caps hurt least. Weekly show, growing audience? Upload-hour caps are predictable.
- Decide whether you need certified measurement. Selling advertising makes it near-essential; otherwise clarity beats certification.
- Check the upload requirements against the export settings you actually use.
- Then, and only then, compare current commercial terms on the vendors' own pages. That is the volatile part of the decision, so make it last, with the durable questions already answered.
