Podcasting has grown into one of the most popular content formats globally, and in 2026 Google actively indexes and surfaces podcast content in search results. Episodes can appear in Google's dedicated podcast results, in general web search for specific topics, and increasingly as sources cited in AI Overviews. Making your podcast discoverable through search requires a specific set of optimisation practices that most podcasters overlook entirely.
How Google Indexes Podcast Content
Google indexes podcasts in two ways: through your RSS feed which carries metadata about each episode, and through transcripts or show notes on your website. Google's AI can also analyse the audio content of episodes directly — it processes spoken content and understands what topics are covered even without a written transcript. However, providing a written transcript significantly improves indexing quality and creates additional ranking opportunities.
Keyword Research for Podcast Topics
Podcast topic selection should be informed by actual search demand. As we covered in our guide to keyword research with AI tools, identifying what your target audience specifically searches for — then recording episodes directly addressing those queries — ensures your content targets proven demand rather than assumed interests.
Topics that rank well in Google web search for informational queries and have growing trend data in Google Trends are ideal podcast subjects. They have confirmed demand, and a well-optimised episode page can capture organic traffic from users who discover the episode through search rather than podcast platforms.
Optimising Episode Show Notes
Every episode should have a dedicated page on your website with comprehensive show notes that function as an SEO article in their own right. Include:
A keyword-optimised title that reflects how people search for the episode's topic — not just an episode number and guest name. As we covered in our guide to title tags that get clicked, search intent alignment is the primary CTR driver.
A full transcript or detailed summary of the episode content. This gives Google comprehensive text to index and creates the keyword density that supports rankings for the episode's topic. Use our keyword density checker to verify appropriate keyword coverage in show notes.
Internal links to related content on your site. Show notes pages with links to related articles create the internal linking structure that builds topical authority as covered in our guide to internal links for rankings.
Podcast Schema Markup
PodcastEpisode and PodcastSeries schema tells Google explicitly that your content is podcast audio. Include episode number, season number, duration, audio file URL, and publication date. As we covered in our guide to advanced structured data, proper schema markup improves eligibility for rich results in podcast search features.
RSS Feed Optimisation
Your podcast RSS feed is the primary distribution mechanism for podcast platforms. Ensure your feed includes: complete episode titles with keywords, comprehensive descriptions of 150–300 words per episode, accurate category tags, and a valid website URL for each episode. Apple Podcasts, Spotify, and other platforms rank podcasts within their own search based partly on the quality of RSS feed metadata.
Summary
Podcast SEO in 2026 requires keyword-informed topic selection, comprehensive show notes pages with full transcripts, PodcastEpisode schema markup, and optimised RSS feed metadata. The combination of a strong website presence with well-optimised show notes and correct schema creates dual visibility in both Google web search and platform-native podcast search.
