Podcast categories: the two slots in your feed and what each one buys

Apple Podcasts sorts 3,154,841 shows into 110 boxes, and podcast categories are the field most hosts fill out once and never look at again. The show count comes from Podcast Industry Insights, the independent catalog tracker published by Daniel J. Lewis, which reports 3,154,841 valid podcasts available in Apple Podcasts against 132,338,415 episodes in feeds, from data it says is "collected independently and updated nightly." The 110 is Apple's own arithmetic: 19 top-level categories and 91 subcategories on the category list it publishes for creators. You get two of those boxes. Almost nobody spends them on purpose.

That is a strange thing to leave on autopilot, because the two slots do completely different jobs, only one of them feeds the charts, and neither one does what most podcasters assume. The assumption is that a category is a keyword, that putting your show in Business instead of Society & Culture makes it findable to people searching for business shows. Apple's own documentation says otherwise, in plain language, on a page almost no one reads.

Nineteen doors and ninety-one rooms

The top level is short enough to hold in your head: Arts, Business, Comedy, Education, Fiction, Government, History, Health & Fitness, Kids & Family, Leisure, Music, News, Religion & Spirituality, Science, Society & Culture, Sports, Technology, True Crime, and TV & Film.

Four of those have no subcategories at all. Government, History, Technology, and True Crime are terminal. A technology show that wants to say it covers cybersecurity rather than consumer gadgets has no field to say it in, which is one reason the Technology category runs as wide as it does.

The rest fan out unevenly. Sports has 15 subcategories, from Baseball and Basketball through Cricket, Golf, Rugby, and Wrestling. Science has 9, including Astronomy, Chemistry, Earth Sciences, Mathematics, and Social Sciences. Leisure has 8, which is where Automotive, Aviation, Crafts, Games, Hobbies, Home & Garden, and Video Games live. Comedy has 3. Music has 3. Fiction has 3.

The unevenness is the first thing worth noticing, because it tells you where Apple expects precision and where it expects a crowd. A running show has a Sports subcategory waiting for it. A show about small business software has Business, and then Entrepreneurship, Investing, Management, Marketing, Non-Profit, or Careers, none of which is about software. The map was drawn for a catalog much smaller than the one it now holds.

The field in the feed

Categories come from your RSS feed unless you set them somewhere else. The podcast namespace documentation at podcast-standard.org describes the tag in one line: "Category of the podcast. Must be one of the iTunes categories. The subcategory is defined by a nested itunes:category tag."

Nested, not listed. A subcategory is not a second category. It sits inside its parent, which means Health & Fitness with Nutrition nested under it is one choice, not two. The second choice is a separate parent tag.

Apple states the limit directly on its category page for creators: "You can choose up to two categories per show, primary and secondary, plus subcategories for each, if available." Most hosting dashboards expose both. Some expose only the first. If your host gives you one dropdown and no second, you are leaving a slot unused, and it is worth an email to support rather than a feed rewrite.

Spotify reads the same field. Its creator support page says categories come from "the itunes:categories field in your RSS feed," and adds that "our editorial team curates categories your show may appear in," so part of the placement there is editorial rather than mechanical. Shows hosted on Spotify for Creators set the field in the submission flow or later from Settings.

What Apple does with the first one

Here is the sentence that should change how you fill the form. From Apple's category documentation: "The primary category is used to display your show in each category page, Top Charts, and personalized recommendations on Home, Search, and within Categories in Library."

Top Charts. Singular path, primary only. The secondary category does not chart you. It gets you onto a browse page and into the recommendation pool, which has value, but the ranked list that podcasters screenshot and put in pitch decks is decided by the first tag in the feed.

That turns category selection into a competitive question rather than a descriptive one. A mid-size interview show about money could honestly file under Business, or under Business with Investing nested, or under Education with Self-Improvement nested. All three are accurate. They are not equally crowded, and the chart you can realistically reach is not the one with the biggest audience. If you are weighing chart position against reach, the download benchmarks in our podcast downloads guide are a better reality check than the chart itself.

Picking the smaller room is not a trick. Apple's content guidelines prohibit metadata that misrepresents the show, and a mystery show filed under Mathematics to game a thin chart is exactly the kind of thing that gets a feed relabeled. The honest version of the move is narrower: among the categories that genuinely describe your show, take the one where your current audience size can place you.

Where search stops caring

Apple publishes a separate page on how search works, and it is specific about what gets indexed. The indexed metadata is "show name, channel name, and episode title." The ranking inputs are three: metadata, "Popularity: podcasts with large followers and plays in Apple Podcasts," and "User Behavior: podcasts with high engagement, such as those that are played or followed from search results." Ratings, reviews, and shares are not factored into search results.

Category is absent from that list. It is not ranked low and it is not weighted lightly, it is not there. Someone typing "nutrition podcast" into Apple Podcasts is matched against show names, channel names, and episode titles, which is why a show called The Nutrition Podcast outranks a better show filed under Nutrition with a clever name. Category drives browse and charts. Titles drive search.

That split has a practical consequence for anyone treating categories as an SEO exercise. The search surface where your category choice genuinely helps you is not inside the podcast apps at all. It is Google, which indexes web pages rather than feed metadata, and which is the reason our podcast SEO guide spends its time on what you publish on the open web rather than on what you tag in your feed. If you have never set up the web side, start with getting your podcast on Google before touching the category field again.

Spotify keeps its own list

Spotify reads your itunes:category tag, then runs its own system on top of it. Its support documentation notes that "chart categories are different to podcast categories elsewhere in the app," which means the thing you browse and the thing you chart in are not the same taxonomy. Apple has one list doing both jobs. Spotify has two, and only tells you about one of them.

The practical read: set the feed field accurately, then check how each app actually files you rather than assuming your tag carried through. Our guide to getting more listeners on Spotify covers the rest of what Spotify does and does not inherit from your feed.

The ampersand problem

Apple's feed requirements page gives one example of a category error, and it is a casing error: <itunes:category text="Kids & family" /> is wrong, <itunes:category text="Kids & Family" /> is right.

That is a lowercase f breaking a category assignment. The strings are matched exactly, and five of the 19 top-level names contain an ampersand that has to be escaped as & in XML: Health & Fitness, Kids & Family, Religion & Spirituality, Society & Culture, and TV & Film. Three more sit in the subcategory list, including Fashion & Beauty and Pets & Animals. If you hand-edit a feed or run a custom generator, this is the single most likely place for it to silently fail, and a show that appears in no category page at all usually has a typo here rather than a penalty.

If you use a mainstream host, the dropdown writes it correctly and this is not your problem. Check it anyway. It takes one view-source.

Picking against the room, not the map

A workable process, in the order it should happen.

Start by listing every category and subcategory that honestly describes the show. Most shows have three or four, not one. Write them down before you look at any chart.

Then open the category page for each candidate in Apple Podcasts and read the top twenty. You are looking for the shows you would be sitting next to, and for how large they appear to be. A category whose top twenty are all network productions with daily output is a category where a weekly independent show will not place. A category whose top twenty includes shows with modest review counts is a category with room.

Then set the primary to the most competitive category you can realistically place in, and the secondary to the widest honest one. The first is a chart bet. The second is a browse and recommendation bet, and there is no reason to spend it on a near-duplicate of the first. Business plus Business News is a wasted slot. Business plus Society & Culture reaches two different browse audiences.

Then write the show title and episode titles as if the category field did not exist, because for search it does not. That is the half of the work that pays, and it is covered in our notes on show notes and episode descriptions.

Changing it later

Category changes propagate the way the rest of your feed metadata does, through a refresh that you do not control the timing of. Apple's documentation on updating podcast metadata describes a detection window measured in hours rather than minutes, so a change made in the morning is not a change you can verify over lunch.

There is no evidence, from any platform's published documentation, that changing a category resets chart history or follower counts. There is also no published guidance saying it is free, so the sensible cadence is to pick deliberately, give it a quarter, and judge it against something measurable rather than against how the page felt. If a category change is part of a larger reset, the month-by-month structure in our first-year growth plan is a better container for it than a one-off edit.

The honest limits

No platform publishes how much traffic category pages send. Apple does not report browse impressions to creators, Spotify does not break out category-driven plays, and anyone quoting you a percentage for category page discovery is quoting an estimate with no primary source behind it. What is documented is the mechanism: primary category feeds charts, browse, and recommendations; search ignores category entirely; both slots come from one feed field that is case-sensitive.

Treat the category field as plumbing that has to be correct rather than as a growth channel. It is a half-hour decision that you make properly once. The channels that actually compound are in our guide to promoting a podcast, and the one that keeps working while you sleep is search on the open web, where your episodes can answer the questions people type into Google.

That is the work PodAnswer does. We take your episodes, find the questions your show already answers better than anyone writing a listicle, and publish those answers as pages that cite your audio with a real timestamp and link back to the episode. Growth is $149 a month for four articles. Network is $349 a month for twelve. The pricing page has the detail, and for podcasters walks through what we need from you to start, which is a feed URL and a list of the topics you want to own.
