For many, SEO is just about websites. That’s Rookie SEO. Think bigger than keywords and rankings. Search has moved on.
People now discover information through podcasts, videos, newsletters, voice assistants, and AI-generated answers that never require a click.
If SEO is about being found, then it can no longer be limited to web pages alone. SEO went off-page some time ago.
This article explores how SEO principles apply to non-web channels – specifically, how you can optimise podcasts, newsletters, and voice-driven search environments for long-term discoverability.
Rethinking What SEO Actually Is
“SEO is about search experience optimization.” Warren Laine-Naida
At its core, SEO is not about rankings or traffic.
SEO is the practice of structuring information so it can be understood, retrieved, and recommended by systems.
Those systems used to be search engines. Today, they also include:
- Podcast and Video platforms
- Recommendation engines
- Voice assistants
- AI systems trained on public content
When the definition is framed this way, the channel becomes secondary. The underlying principles remain the same.
Podcast SEO: How Audio Content Gets Discovered
Audio itself is not searchable. Text is.
Podcast platforms rely on metadata and contextual signals to determine what a show or episode is about and when it should be recommended.
Where Podcast Discovery Happens
Podcast discovery typically occurs through:
- Apple Podcasts and Spotify search
- Google and YouTube audio indexing
- Voice-based queries such as “Play a podcast about…”
- AI-powered podcast search tools
- … or right here!
None of these systems truly understands audio in the way a human listener does. They depend on structured text signals.
The Real SEO Assets of a Podcast
“Natural language and clarity matter for SEO.” Warren Laine-Naida
From a discoverability perspective, the most important components of a podcast are:
- Show title and description
- Episode titles
- Episode descriptions
- Show notes
- Transcripts
- External references and links
The audio file itself is only part of the equation.
Practical Podcast Optimization Principles
Clear, descriptive episode titles.
Episode titles should describe the topic directly. Clever or vague titles reduce discoverability.
Intent-focused episode descriptions.
Descriptions should explain what problem the episode addresses, who it is for, and what topics are covered.
Transcripts as a foundation, not an extra.
Transcripts enable:
- Search engine indexing
- AI summarization and citation
- Quote-level discovery
- Accessibility
Without transcripts, podcast content is largely invisible to machines.
Consistent topical focus. Podcasts with a clear thematic focus send stronger signals to platforms and recommendation systems than shows with scattered topics.
Video SEO: How Moving Images Get Found
“With all of my heart, I’d love it if more YouTube videos had: — edited SRT files — Chapters in the description.” Bridget Willard
Video works differently from audio. But it faces the same problem.
Systems can’t watch videos. They read the text around them.
Where Video Discovery Happens
People find videos through YouTube search. Through Google video results. Through social media feeds. Through AI-powered content recommendations.
YouTube is the second-largest search engine after Google. And Google owns it. That means video SEO is search SEO.
The Real SEO Assets of Video
For video discoverability, what matters:
Video title. Description. Tags. Captions and subtitles. Thumbnails. Chapters. Engagement signals like watch time and click-through rate.
The video content itself matters for retention. But discoverability lives in the metadata.
How to Optimize Video for SEO
Write titles for search intent, not clicks.
The best title answers what someone is searching for. Clickbait might get the first view. Clear titles get sustained discovery.
Use the first two sentences of your description wisely.
That’s what shows in search results. Make them count.
Add captions and transcripts.
YouTube can auto-generate them, but manual ones are better. They improve accessibility and give search engines more text to index.
Break videos into chapters.
Chapters create timestamp links that can surface independently in search. They also improve user experience.
Design thumbnails for clarity, not drama.
People scan thumbnails fast. Simple, readable text and clear imagery win over complex designs.
Optimize for watch time, not just views.
Platforms prioritize videos that keep people engaged. Strong intros matter. So does pacing.
Create consistent content.
Like podcasts, videos with a focused theme build stronger signals than scattered topics. YouTube rewards specialization.
Newsletter Discoverability: The Overlooked SEO Channel
Email is often viewed as private and ephemeral, but newsletters increasingly function as long-term content assets.
When newsletter archives are publicly accessible, they become part of the searchable web and part of the training data ecosystem for AI systems. Another thing to think about: the sign up pages for your Newsletter is probably indexed there in Google and Bing too.
How Newsletters Get Discovered
Newsletter content can surface through:
- Search engine results
- Brand and author queries
- AI-generated summaries
- Curated resource lists
Over time, consistent publishing builds authority in the same way a blog does.
Optimization Principles for Newsletters
Treat each issue as a standalone resource.
Each edition should focus on a single topic and answer a specific question.
Publish public archives.
If content exists only in inboxes, it cannot contribute to discoverability or authority.
Use internal linking across issues.
Linking between related newsletter editions reinforces topical relevance and helps systems understand content relationships.
Consistency over volume.
A steady publishing cadence builds trust signals more effectively than sporadic output.
Voice and AI Search: Optimization Without the Screen
“Make your content visible to both people and machines.” Warren Laine-Naida
Voice queries and AI-driven search interfaces favor natural language and direct answers.
Users do not speak the way they type. They ask complete questions and expect concise responses.
How Voice-Based Discovery Works
Voice assistants and AI systems typically rely on:
- Clear, direct explanations
- Structured content
- Authoritative sources
- Featured snippet-style answers
Optimization Principles for Voice Search
Answer questions explicitly.
Content should clearly state the question being addressed and provide a direct answer.
Use conversational language.
Natural phrasing aligns better with spoken queries and AI interpretation.
Favor clarity over complexity.
Short, well-defined explanations are more likely to be surfaced than long, abstract discussions.
Authority matters more than novelty.
Accuracy, consistency, and trustworthiness outweigh creative phrasing.

SEO in a No-Click Environment
Discoverability no longer guarantees traffic.
Content may be summarized, read aloud, or cited without a direct visit to the source. This does not mean SEO has lost its value.
Instead, the focus shifts toward:
- Visibility
- Recognition
- Brand recall
- Trust
These signals compound over time, even when clicks decrease.
Final Thoughts
SEO is no longer confined to websites.
Podcasts, videos, newsletters, and voice-driven platforms all rely on the same foundational principles: clarity, structure, and usefulness.
When content is created with these principles in mind, it becomes discoverable across channels, formats, and systems – often in ways that cannot be fully predicted in advance.
That is not a limitation of modern SEO. It is its evolution.
