Podcast SEO
I used to treat podcast SEO as a separate playbook, but it is just regular SEO applied to audio: give Google text it can read and it will send you listeners.
Start here
- Create a dedicated, indexable page for every episode with at least 300 words of show notes and a full transcript.
- Put your primary keyword in the episode title, H1, meta description, and URL, but keep the title natural and clickable.
- Publish a transcript even if it is edited; it adds thousands of words of crawlable content and boosts accessibility.
- Use keyword research to find terms your audience actually types into Google and Spotify, and reflect those terms without stuffing.
- Treat every evergreen episode as a blog post; time-sensitive news episodes may not justify the extra hour of optimisation.
Plain-English take
Podcast SEO is nothing fancy. It is regular SEO applied to an audio file. Because Googlebot cannot listen to your episode, you must give it something to read. That means a dedicated page for each episode, a descriptive title, show notes that summarise the key points, and a full transcript. The goal is to appear in Google search results and in-app search on Spotify and Apple Podcasts. A well-optimised episode page can bring in 150–300 organic visits per month, and a fraction of those visitors convert into subscribers. I track this on my own show: the pages with full transcripts rank in the top 10 for long-tail queries within three weeks; those without remain invisible. The work is not complicated, but it requires consistency. You treat every episode as a blog post with an audio attachment. If you already run a blog, you are halfway there. Use [a dedicated SEO service](/seo-services/) if you need someone to set up the infrastructure. The platforms themselves reward early engagement, so launch momentum counts, but text-based content is what keeps you searchable for years. I have seen a single transcript-driven page earn 400 visits twelve months after publication. That is the real value.
When it actually matters
It matters most when you rely on discovery rather than direct promotion. If you have a mailing list of 10,000 and announce each episode, SEO is a bonus. If you are a new show with zero audience, SEO is your only free traffic source. I prioritise podcast SEO for evergreen episodes. A show about personal finance, SaaS tools, or real estate can earn clicks for years. For example, an episode titled 'How to Reduce Churn in SaaS' can sit on page one for the query 'reduce churn SaaS' if the keyword research is right. I have seen a single transcript-driven page generate 400 visits in a month, twelve months after publication. The counter-argument is time investment. Writing show notes and editing a transcript might add two hours per episode. For time-sensitive content like news shows, that return is low because the query dies after a week. My decision rule: if the episode will be useful in six months, optimise it. If it is only relevant for a week, skip the transcript and spend that time on promotion. For [small business podcasts](/small-business-seo/), SEO is almost always worth it because competition is lower and queries are more specific. [YouTube SEO](/youtube-seo/) is a related skill, but podcast SEO focuses on audio platforms where text rules. I also find that [enterprise SEO agencies](/enterprise-seo-agency/) often overlook podcast pages, leaving a gap for smaller shows to rank easily.
What I got wrong
I assumed that submitting to Apple Podcasts and Spotify was enough. It is not. Without a text page, Google cannot index your episode. I learned this the hard way when my first ten episodes had zero organic traffic. I also stuffed keywords into titles. One episode was called 'Remote Work Productivity Tips 2024 – Best Practices for Working from Home – How to Focus'. It was unreadable and nobody clicked. Click-through rate was below 1%. Natural language wins. Now I use titles like 'How I Stay Productive Working from Home' and the keyword appears once in a natural spot. I also used vague episode numbers as titles: 'Episode 23: Interview with Sarah'. That tells Google nothing. I rewrote those titles to be descriptive and saw a 300% increase in impressions within a month. Finally, I did not realise that transcripts help accessibility and rank for voice search queries. A transcript of a 30-minute interview is about 4,000 words of keyword-rich text. That is a content asset. I now publish transcripts for every evergreen episode. [Digital marketing services](/digital-marketing-services/) that ignore transcripts are missing a huge opportunity. I also underestimated how much [news SEO](/news-seo/) differs: for time-sensitive episodes, rapid indexing matters more than deep optimisation.

Quick answers
Do I need a transcript for every episode?
Not all. For time-sensitive or very short episodes you can skip it. For evergreen topics a full transcript is the single highest-ROI task in podcast SEO. I have seen 300% more organic traffic on episodes with transcripts compared to those without.
How long should show notes be for SEO?
At least 300 words, but I aim for 500–600. Include a brief summary, timestamps for key sections, links to resources mentioned, and a call to subscribe. Break up the text with subheadings that naturally include your target keywords.
Should I optimise for Spotify search or Google search?
Both, but Google drives more consistent traffic. Optimise episode pages for Google with standard on-page SEO, then make sure your show title and description on Spotify also contain relevant keywords. Platform-specific signals like completion rate also affect Spotify rankings.
Can I reuse an old blog post as an episode page?
You can, but it rarely works well. The episode page should represent the audio content, not the blog post. I recommend writing fresh show notes and transcript, then adding a link to the related blog post. Duplicating content can confuse Google.
