TL;DR
Podcast audio files are invisible to Google. Your show notes page is the only thing that can rank. Most podcasters treat show notes as an afterthought (timestamp links and guest bio), which gives Google nothing to work with. The podcasters who rank treat each episode’s show notes as a standalone article targeting a specific search query. The audio is the content; the show notes are the SEO asset. They require separate strategies.
The Conversation
Kenji, business podcast host, 150 episodes over 3 years, zero organic traffic despite quality guests and growing download numbers: I’ve been podcasting for three years. Downloaded over 2 million times. But when I check Google Analytics, organic search traffic to my podcast pages is basically zero. How is that possible?
SDC SEO Brain: Because Google can’t listen to your podcast. Audio files are opaque to search engines. Google sees an MP3 embed and a page with some text around it. If that text is thin (guest name, episode title, maybe timestamps), Google has nothing to index. Your 2 million downloads came from podcast apps, social promotion, and word of mouth. Search wasn’t a channel because you didn’t build for search.
Kenji: But I have show notes for every episode. Guest bio, bullet points of what we discussed, links to resources mentioned.
SDC SEO Brain: How many words are your typical show notes?
Kenji: Maybe 200 to 300 words? Sometimes less.
SDC SEO Brain: There’s your problem. 200 words with bullet points of topics isn’t enough for Google to consider it substantial content. You’re competing against 2,000-word articles written specifically to rank for the same topics. Your show notes are metadata, not content.
Kenji: So I need to write articles for every episode? I already spend hours producing the audio.
SDC SEO Brain: You don’t need articles for every episode. You need to identify which episodes have ranking potential and invest in those. Not every episode targets a searchable query. An interview titled “My Conversation with John Smith” has no search demand. An episode titled “How to Negotiate a Higher Salary” does. The second one deserves substantial show notes. The first one doesn’t.
Kenji: How do I know which episodes have search potential?
SDC SEO Brain: Look at your episode topics through a keyword research lens. Would someone type this into Google? “How to build a remote team” is searchable. “Episode 47: Catching Up with Sarah” is not. Pull your episode list and categorize them. Some are interview-driven (search potential is the guest’s expertise topic). Some are topic-driven (search potential is the topic itself). Some are neither (news commentary, personal updates). Only invest SEO effort in the first two categories.
Kenji: What about transcripts? I’ve heard those help with SEO.
SDC SEO Brain: Full transcripts are a trap for most podcasters. They’re long, but they’re not structured for search. A one-hour conversation transcript is 8,000 to 10,000 words of rambling dialogue with no clear hierarchy. Google sees it as one massive block of text with no organization. It might help with some long-tail queries if someone searches an exact phrase you said, but it won’t rank for the main topic because the content isn’t optimized.
Kenji: So transcripts don’t help?
SDC SEO Brain: They help accessibility and they provide raw material. But raw transcripts aren’t SEO content. The strategic approach: use the transcript as source material to write proper show notes. Pull the key insights, structure them with headers, add context the conversation didn’t include. The transcript becomes your research, not your published content.
Kenji: That sounds like a lot of work per episode.
SDC SEO Brain: It is. Which is why you don’t do it for every episode. If you publish weekly, maybe one episode per month gets the full SEO treatment. That’s 12 pieces of substantial content per year targeting specific keywords. Better than 52 episodes with thin show notes that rank for nothing.
Kenji: How long should the SEO-focused show notes be?
SDC SEO Brain: Long enough to compete with what’s currently ranking. Search your episode’s target keyword. Look at the top 5 results. How long are they? How are they structured? What subtopics do they cover? Your show notes need to be at least as comprehensive. If competitors have 1,500-word guides, your 300-word bullet list won’t compete. This doesn’t mean longer is always better. It means comprehensive coverage of the topic is required.
Kenji: What about the episode title? Should that be keyword-optimized?
SDC SEO Brain: Episode titles serve two purposes that sometimes conflict. For podcast apps, catchy and curiosity-driven titles get clicks. For SEO, clear keyword-focused titles rank. You can split the difference. Your page title (what appears in Google) can be different from your episode title in podcast apps. Many hosting platforms let you set these separately. “Episode 127: The Salary Talk Nobody Wants to Have” for Apple Podcasts. “How to Negotiate a Higher Salary: Expert Strategies” for the webpage title tag.
Kenji: I didn’t know I could have different titles.
SDC SEO Brain: Most podcast hosts allow separate fields for RSS feed title (what podcast apps see) and page title (what Google sees). Check your hosting platform settings. If they don’t support this, you can manually edit the page title in your CMS while keeping the embedded player title different.
Kenji: What about the URL structure? My episodes are at /podcast/episode-127/.
SDC SEO Brain: Numeric URLs waste SEO opportunity. /podcast/episode-127/ tells Google nothing about the content. /podcast/how-to-negotiate-salary/ immediately signals relevance for salary negotiation queries. Changing existing URLs requires redirects and is probably not worth the effort for 150 old episodes. But going forward, use descriptive slugs for episodes you’re optimizing.
Kenji: What if an episode covers multiple topics? Like an interview where we discuss career advice, then productivity, then investing?
SDC SEO Brain: You have to choose. One page can realistically rank for one main topic. If an episode genuinely covers three separate topics in depth, you have options. First, optimize for the strongest topic where you have the most ranking potential. Second, create separate landing pages for each topic that reference the relevant portion of the episode. Third, accept that this episode isn’t an SEO play and optimize future episodes more narrowly.
Kenji: Separate landing pages from the same episode? Isn’t that duplicate content?
SDC SEO Brain: Not if the pages are genuinely different. Each page focuses on one topic, includes different headers and structure, and timestamps to the relevant portion of the episode. The audio embed is the same, but the surrounding content is unique. Google evaluates the page, not just the embedded media. Think of it as three articles that each happen to include the same interview as supporting media.
Kenji: That’s interesting. What about podcast directories like Apple and Spotify? Do those help with SEO?
SDC SEO Brain: Apple Podcasts and Spotify are closed ecosystems. They don’t pass authority to your website. Being listed helps you get discovered within those platforms, but Google treats them as separate entities. What does help is if your podcast gets featured on third-party sites that link to your show notes. Guest appearances where the host links to your episode page. Roundups and recommendations from industry sites. Those backlinks help your pages rank.
Kenji: I’ve done dozens of guest appearances but they usually link to my podcast on Apple or Spotify.
SDC SEO Brain: That’s a missed opportunity. When you guest on other shows, request they link to your website’s episode page, not Apple Podcasts. You can even provide the specific URL. “Here’s where your listeners can find the show notes with all the resources we mentioned.” That turns guest appearances into a link building strategy.
Kenji: Good point. What about schema markup? I’ve seen podcast episodes show up in Google with special formatting.
SDC SEO Brain: PodcastEpisode schema can help Google understand your content and potentially display rich results. You’d mark up each episode with properties like name, description, datePublished, audio file URL, and associatedMedia. Most podcast hosting platforms don’t implement this automatically, so you might need to add it manually or through a plugin. The benefit is clarity signals to Google plus potential for enhanced search appearance.
Kenji: Is schema worth the effort?
SDC SEO Brain: For a 150-episode archive, probably not worth adding retroactively. For new episodes you’re optimizing for search, yes. It takes 10 minutes per episode once you have a template. The rich result potential isn’t guaranteed, but the clarity signals help Google categorize your content correctly.
Kenji: Let me ask about something different. My podcast is on a subdomain: podcast.mybusiness.com. Does that hurt SEO?
SDC SEO Brain: Potentially. Google treats subdomains somewhat independently from main domains. Authority built on your main domain doesn’t fully transfer to the subdomain. If your main site at mybusiness.com has strong authority, your podcast pages at podcast.mybusiness.com don’t automatically benefit. The strategic choice is either move the podcast to mybusiness.com/podcast/ (a subfolder) or accept that the subdomain builds its own authority separately.
Kenji: Moving 150 episodes with redirects sounds like a nightmare.
SDC SEO Brain: For an established podcast, migration is risky. The better approach might be keeping the subdomain but building links specifically to it. Guest appearances link to podcast.mybusiness.com. Your main site’s navigation includes links to the podcast. Over time, the subdomain builds authority. It’s not ideal, but it’s better than a botched migration.
Kenji: What’s the priority order here? I’m feeling overwhelmed.
SDC SEO Brain: Start simple. First, audit your 150 episodes and identify 10 to 15 with the highest search potential. These are topic-driven episodes on subjects people actually search for. Second, for those episodes, expand show notes to 800 to 1,500 words with proper structure (headers, key points, actionable takeaways). Third, update page titles and URLs for those episodes to be keyword-focused. That’s your foundation.
Kenji: And after that?
SDC SEO Brain: Fourth, implement PodcastEpisode schema on optimized episodes. Fifth, start requesting website links instead of Apple Podcasts links when guesting on other shows. Sixth, for new episodes, decide at the planning stage whether this is an SEO episode or not. If yes, plan the topic around a keyword and create proper show notes from the start.
Kenji: This is basically treating some podcast episodes like blog posts.
SDC SEO Brain: Exactly. The audio is the experience. The show notes are the search asset. They serve different audiences through different channels. Someone searching “how to negotiate salary” finds your show notes, gets value from the written content, and might then listen to the episode for depth. Someone browsing Apple Podcasts finds the episode directly. Both paths work, but they require different content strategies.
Kenji: One more thing. My podcast covers business topics broadly. Should I narrow down for SEO purposes?
SDC SEO Brain: Topical focus helps. A podcast that covers everything from marketing to finance to operations competes for broad terms against specialists. A podcast focused specifically on “career growth for mid-level managers” can dominate a narrower space. You don’t have to change your podcast’s scope, but your SEO-optimized episodes should cluster around themes where you want to build authority.
Kenji: So even if I interview guests on various topics, I emphasize certain themes in my SEO efforts?
SDC SEO Brain: Right. Your guest might discuss productivity, management, and personal finance in one conversation. Your SEO-optimized show notes focus on management because that’s your target cluster. The transcript captures everything, but the structured content emphasizes your strategic keywords. You’re curating the episode’s searchable identity, not just documenting what was said.
Kenji: This makes me realize I’ve been leaving a lot of search traffic on the table.
SDC SEO Brain: Most podcasters do. Podcast SEO is an afterthought in an industry that measures success by downloads. But downloads are one-time discovery. Search traffic compounds. An optimized show notes page can bring visitors for years. That episode you published in year one still ranks and still converts listeners. The math favors investment in search even though the podcast world doesn’t emphasize it.
FAQ
Q: Why doesn’t my podcast get any organic search traffic?
A: Google can’t listen to audio files. Your show notes page is the only indexable content, and if it’s just bullet points and timestamps (200 to 300 words), Google considers it thin content. Podcasts get discovered through apps, social media, and word of mouth. Search traffic requires treating show notes as proper SEO content, not as episode metadata.
Q: Should I use full transcripts for podcast SEO?
A: Raw transcripts are poor SEO content despite being long. A one-hour conversation transcript is 8,000+ words of unstructured dialogue with no hierarchy or optimization. Use transcripts as source material to write proper show notes. Pull key insights, structure with headers, add context. The transcript is research, not publishable content.
Q: How long should SEO-optimized podcast show notes be?
A: Long enough to compete with what currently ranks. Search your target keyword and analyze the top results. If competitors have 1,500-word guides, your 300-word bullet list won’t compete. Comprehensive coverage of the topic matters more than hitting a specific word count. For most competitive topics, 800 to 1,500 words with proper structure is the minimum.
Q: Should podcast episode titles be keyword-optimized?
A: You can have different titles for different platforms. Podcast apps favor catchy, curiosity-driven titles that get clicks. Google favors clear, keyword-focused titles that signal relevance. Most hosting platforms let you set page title (for SEO) separately from episode title (for RSS feeds). Use both strategically.
Q: Do links to my Apple Podcasts or Spotify page help my website’s SEO?
A: No. Apple Podcasts and Spotify are closed ecosystems that don’t pass authority to your website. When guesting on other shows, request links to your website’s episode page, not platform listings. “Here’s where listeners can find show notes with all resources mentioned.” This turns guest appearances into link building for your site.
Summary
Podcast audio files are invisible to search engines. Google can’t listen to your episodes. Only the show notes page can rank, and most podcasters create show notes too thin to compete (200 to 300 words of bullet points and timestamps versus 1,500-word articles targeting the same keywords).
Not every episode deserves SEO investment. Interview-driven episodes where guests discuss their expertise have search potential. Topic-driven episodes (“How to Negotiate a Higher Salary”) have search potential. Commentary episodes and personal updates don’t. Categorize your archive and focus optimization effort on episodes with genuine keyword opportunity.
Full transcripts are a trap. They’re long but unstructured. 8,000 words of rambling dialogue doesn’t rank for the main topic because it lacks hierarchy and optimization. Use transcripts as source material to write proper show notes, pulling key insights and structuring them with headers and context. The transcript becomes research, not published content.
Episode titles can differ by platform. RSS feed titles (for podcast apps) can be catchy and curiosity-driven. Page titles (for Google) should be keyword-focused. Most hosting platforms support separate fields. “Episode 127: The Salary Talk Nobody Wants to Have” for Apple Podcasts. “How to Negotiate a Higher Salary: Expert Strategies” for the webpage.
Subdomain versus subfolder matters. podcast.mybusiness.com doesn’t fully inherit authority from mybusiness.com. Google treats subdomains somewhat independently. mybusiness.com/podcast/ (subfolder) better leverages existing domain authority. For established podcasts, migration is risky; building subdomain authority through dedicated link building is often the safer path.
Guest appearances are link building opportunities. When appearing on other podcasts, request links to your website’s episode page, not Apple Podcasts or Spotify listings. Platform links don’t pass authority to your site. Provide specific URLs: “Here’s where listeners can find all resources we mentioned.”
Topical clustering accelerates authority. A podcast covering everything competes broadly against specialists. SEO-optimized episodes should cluster around themes where you want to build authority. Even if a guest discusses multiple topics, the show notes emphasize your strategic keywords. You’re curating the episode’s searchable identity.
Podcast SEO compounds over time. Downloads are one-time discovery. Search traffic continues indefinitely. An optimized show notes page from year one still ranks and converts listeners in year five. The investment math favors search optimization even though the podcast industry measures success primarily by download numbers.
