Character Count Design for Podcast Show Notes - Platform Limits and Optimization Strategies

A podcast's show description and episode notes are critical touchpoints that determine whether listeners discover your show and hit the play button. However, major platforms like Apple Podcasts, Spotify, YouTube Music, and Amazon Music each impose different character limits, meaning the same text may get truncated differently across platforms. This article provides a precise breakdown of each platform's limits and explains how to design your character counts to deliver optimal information to every listener.

Character Limits by Platform

Podcast character limits differ between the overall show description and per-episode descriptions. Additionally, the number of visible characters varies between "collapsed view" in search results or cards and "full view" on detail pages.

The figures below are practical reference points as of August 2026, drawn from what you can see in publishing dashboards and each company's help pages. Some platforms do not state a character limit in their official documentation at all, and the values move as specifications change. Before you commit to a format, check the input field of the platform you actually publish to.

The design principle is to fit the whole text to the platform with the smallest allowance. Even if you write a 3,000-character description for Apple Podcasts, the later half never reaches listeners on a platform whose show description field sits in the 1,000-character range. If you distribute across multiple platforms, keep your core information inside the first 1,000 characters and treat everything after that as supplementary.

Google Podcasts, incidentally, was announced for shutdown in September 2023, closed in March 2024, and was folded into YouTube Music. Older explainer articles may still list it as a destination, but today you only need to look at how YouTube Music handles your feed.

Search Result Display - The First Two or Three Lines Decide

Most listeners discover podcasts through in-platform search. Card displays in search results cut the show description off after a few lines, and how much text fits into those lines is not a fixed number. Apps collapse by line count rather than character count, so the visible amount changes whenever the screen width, the system font size setting, or the app's own layout changes. Treat the first two or three lines as the part that will definitely be read, and everything past it as a bonus for listeners who tap to expand. Designing around that fold is the same discipline as meta description design.

Information to include in the opening section visible in search results:

• Genre and theme: Convey your show's positioning in one sentence, such as "A podcast exploring the intersection of technology and business"
• Update frequency: Include information listeners use for subscription decisions, like "New episodes every Monday"
• Target audience: Clearly state who the show is for, such as "For startup founders and product managers"
• Differentiator: Show what sets you apart, like "Active CTOs invite guests to candidly share their failure stories"

Starting with preambles like "This show is about..." or "In this podcast, we..." fills part of the visible area with zero information. When only a few lines show, dropping the throat-clearing and leading with the core message is more effective.

Episode Description Structure Techniques

Episode descriptions (show notes) serve a different role than show descriptions. While the show description helps listeners decide "Should I listen to this show?", episode descriptions serve two purposes: "Should I listen to this episode?" and "Reference material after listening."

Effective episode descriptions follow a three-layer structure:

Design the Layer 1 hook to fit the first two or three lines that stay visible without expanding in any app. Leading with the guest's name, the topic, and specific numbers, as in "This week we welcome former Google engineer Tanaka to share 3 lessons learned from large-scale system outages," means the substance still lands even when nobody taps to read more. Put a greeting or a sponsor announcement in that position instead, and listeners scroll to the next show without ever seeing anything to judge you by.

Layer 3 timestamps are especially important for long episodes (30+ minutes). An episode you have to scrub through from the start to find the part you want gets postponed, while a table of contents turns the same episode into something you can start right now. Some apps treat a time notation like "12:30 - Topic name" as a link to that playback position, so keep the format intact and the times accurate.

Using description vs. content:encoded in RSS Feeds

Podcast RSS feeds have two main fields for storing text: the <description> tag and the <content:encoded> tag. How you use these two directly affects display differences across platforms.

Which field an app reads, and in what order of preference, differs from app to app and is not always spelled out in official documentation. That makes "put the information in one field only" a design that ends with an empty description box somewhere. The practical recommendation is dual management: store a plain text version (under 1,000 characters) in description and an HTML version (with links and timestamps) in content:encoded. Write the plain text version so that a listener who sees only that still has everything needed to decide, without depending on links.

There is no reason to invest in itunes:summary for a new RSS feed. If your existing feed already carries it, set content that does not contradict description. When all three fields say different things, the description a listener sees changes depending on which app they use.

Writing SEO-Optimized Show Notes

Podcast SEO requires thinking along two axes: search optimization for the audio content itself and text search optimization for show notes. Apple Podcasts and Spotify each have their own search algorithms, requiring a different approach from YouTube description SEO.

None of these companies publish how their search works, but you can confirm for yourself that in-app search draws on the text of show names, episode titles, and descriptions: simply search for your own show. The corollary is that a word which never appears in your description cannot lead anyone to you. Before publishing, it is worth checking once whether the words someone would actually type to find that episode appear naturally in the text.

Play counts and completion rates are often discussed as ranking factors, but that is not a published specification. The only side you can reliably control is the text, so tidying up the show notes first is where your effort pays off.

• Natural keyword placement: Include keywords related to the episode's theme naturally within the first 200 characters
• Guest full names: Many listeners search by guest name, so always include full names and titles
• Specific topic names: Rather than "Talking about the cloud," write in the searcher's own words, as in "What one company found when it costed out moving back on-premises"
• Consistent series naming: For ongoing series, use unified naming like "Series Name #3" to support series-based searches

Title Character Count Design

Episode titles face even stricter character limits than show notes. While sharing many commonalities with video title optimization, podcasts have their own unique constraints.

As with show descriptions, several companies do not publish a number for the title input limit (as of August 2026). The values below are what you can observe in the input fields, but the figure that matters in practice is not the ceiling: it is the length that stays readable in a list view without being cut off.

The recommended lengths sit far below the ceilings because list views break titles off after one or two lines. Anything past roughly 35-50 characters is safest treated as text that will not be read. If you include an episode number (e.g., "#127" = 4 characters), you effectively have 30-45 characters to work with.

Avoid repeating the show name inside episode titles. In a title like "Tech Talk - Tech Talk #127 The Future of Generative Models," the show name is already displayed separately on the show page and in app lists, so the repetition spends limited display width on information the listener already has. Spend that same width on something specific to the episode and you give them one more reason to press play.

Chapter Markers and Character Counts

Chapter markers are a mechanism for giving titles, and sometimes images, to sections inside an episode. There are two families: markers embedded in the audio file itself, and the Podcasting 2.0 style, where the RSS feed points to an external JSON file. Which one an app understands differs from app to app. In an app that supports neither, chapters simply do not appear, so writing the same timestamps into the description as well is the practical belt-and-braces approach.

The recommended character count for chapter titles is 20-40 characters. Chapters sit in a narrow list, so assume they get cut off even earlier than a description does. Titles that name the content, like "Why Rust is gaining attention in embedded development," serve a listener hunting for the part they want far better than generic labels like "Introduction" or "Summary."

Show Description Templates and Examples

Here are genre-specific templates for creating effective show descriptions efficiently.

Interview shows (recommended 800-1,200 characters)

• First 100 chars: Show concept and host introduction
• 100-300 chars: Types of guests and notable past guests
• 300-500 chars: Value for listeners (learning, insights, entertainment)
• 500-800 chars: Update frequency, episode length, social media accounts
• 800-1,200 chars: Sponsor information, listener mail, related links

News commentary shows (recommended 600-1,000 characters)

• First 100 chars: News genre covered and analytical perspective
• 100-300 chars: Host's expertise and background (establishing credibility)
• 300-600 chars: Show characteristics (breaking news, deep dives, original reporting)
• 600-1,000 chars: Publishing schedule, related media, contact information

For both templates, take the platform whose show description field is narrowest as your baseline (in the table above, the one in the 1,000-character range) and concentrate core information in the first half. Treat anything past 1,000 characters as bonus information that only gets read in apps with room to spare, and move reference links and sponsor details there. Laid out that way, the material a listener needs in order to judge your show arrives no matter which app they open it in.

Your Real Limit Is Set by the Hosting Service

So far we have looked at limits on the platform side, but the number of characters you can actually write is decided by the input fields of your hosting service. Every app simply reads the RSS feed the host generates, so if the host's field is short, all the headroom on the Apple Podcasts side counts for nothing.

Hosting services do not necessarily publish their limits as a documented specification, and the limits change with feature updates. Rather than relying on numbers quoted in someone else's article, the one reliable method is to check in the dashboard of the service you pay for. Three steps will tell you what you need to know:

• Watch how the input fields behave: Paste a long block of text into the show description and episode description fields and see whether a character counter appears, or whether typing simply stops
• Check how HTML is handled: Insert links and line breaks, save, and confirm whether they survive on the public page (some services flatten everything to plain text)
• Read the generated RSS directly: Open the feed URL in a browser and see with your own eyes what ended up in description and content:encoded

The trap worth watching for is a service whose show description field is far shorter than its episode description field. A show description is a piece of writing you use for a long time once written, so where the limit is tight, narrow it to three things - update frequency, target listener, and the show's angle - and let the episode side carry everything else.

A/B Testing Episode Descriptions

The optimal character count for episode descriptions varies by show genre and listener demographics. A/B testing is effective for finding data-driven answers. While podcast A/B testing isn't as straightforward as website testing, the following methods allow indirect measurement:

• Alternating tests: Publish even-numbered episodes with short descriptions (under 300 chars) and odd-numbered with long descriptions (800+ chars), then compare play counts and completion rates
• Hook comparison: Alternate between "question format" and "conclusion-first format" for the opening 100 characters, comparing play start rates
• Timestamp presence: Compare completion rates between episodes with and without timestamps. Which way the effect runs varies with episode length and genre, so confirm it against your own numbers rather than assuming another show's result carries over
• CTA placement: Compare follower growth rates when placing "Subscribe" or "Leave a review" requests at the beginning vs. end of descriptions

Apple Podcasts Connect and Spotify's creator dashboard (named Spotify for Creators as of August 2026) let you check per-episode play counts, completion rates, and follower changes. Cross-referencing these metrics with description character counts and structure helps you find the optimal design for your show.

Audio Transcripts and SEO

Apple Podcasts began displaying transcripts of episode audio with iOS and iPadOS 17.4, released in March 2024. The point worth noting is which languages it covers: at launch the feature was available for English, French, German, and Spanish, so whether it applies to your show depends on the language you publish in (as of August 2026).

You will also see it claimed that transcripts are indexed for search and that keywords in show notes therefore matter less. Neither company documents whether transcript text feeds in-app search, or how, so treat that as an assumption rather than a specification. What is certain is that the text an app definitely has to work with is your show name, episode titles, and descriptions.

That asymmetry is convenient for you in practice. As with SEO character count considerations, text you control completely turns into an asset in proportion to what you write. Even if transcripts eventually cover more languages, structured information such as timestamps, reference links, and a guest's title cannot be generated automatically out of audio, so time spent tidying your show notes never goes to waste.
