A podcast episode without accompanying written content is largely invisible to search engines, no matter how good the audio is.
Publish a Real Show Notes Page
A dedicated page per episode with a genuine summary, not just an embedded audio player, gives search engines something to index.
Include Full or Partial Transcripts
Transcripts turn spoken content into searchable text and often surface long-tail phrases naturally.
Link Between Related Episodes
Cross-linking episodes on similar topics helps both listeners and search engines understand your show's overall topical coverage.
