Automate show notes and SEO posts from vertical episodic videos using repeatable prompts and rewrite templates for faster publishing and better discovery.

Hook: Stop letting vertical episodes sit unearned — automate show notes and SEO-ready posts

If you publish episodic vertical video (Reels, Shorts, TikToks, Holywater episodes) you know the grind: record, edit, post — and then manually write show notes, timestamps, transcripts, and a blog post that actually ranks. That manual work kills scale, consistency, and brand voice. In 2026, with vertical streaming platforms and AI-first tooling exploding, publishers who automate show notes generation with rewrite templates win distribution and SEO. This guide gives a step-by-step automation recipe to convert batches of vertical episodes into transcripts, polished show notes, and long-form SEO posts — fast, repeatable, and brand-safe.

The context: Why automate show notes for vertical episodic content in 2026?

In late 2025 and early 2026, investment and product moves accelerated around mobile-first episodic video. Notably, Holywater raised $22M in January 2026 to scale AI-driven vertical streaming and serialized microdramas, illustrating a larger shift: platforms are optimizing for vertical, episodic attention and data-driven discovery. Search and social still need text to index, summarize, and surface episodes. Automation is not optional — it’s required to:

Increase discoverability across search (SEO posts) and podcast directories (show notes).
Maintain consistent brand voice across hundreds of micro-episodes.
Reduce legal and duplicate-content risk while repurposing media at scale.

Holywater’s funding in January 2026 underscores the growth of AI-powered vertical episodic content — and the need for automated, SEO-ready text that makes episodes searchable.

High-level automation workflow (overview)

Here’s the end-to-end flow we’ll implement. Each stage includes tools, prompts, and rewrite templates you can copy.

Ingest vertical video (source capture)
Transcribe and auto-segment (ASR)
Generate raw show notes and timestamped bullets (LLM prompt)
Apply rewrite templates for brand voice and SEO variants
Generate long-form SEO posts (podcast-to-blog conversion)
Quality checks, canonical tags, and publish via CMS

Step 1 — Ingest: Capture vertical episodes reliably

Automated pipelines start with consistent metadata and storage. For each episode, capture:

Episode slug (YYYY-MM-DD-guest-topic)
Source file (MP4 vertical — 9:16)
Episode metadata: host, guest, series, tags, platform (TikTok/YouTube Shorts/Holywater)

Store assets in a predictable place (e.g., an S3 bucket or cloud folder). Use webhooks from publishing platforms or an upload form to trigger the pipeline.

Quick implementation options

Zapier/Make/n8n to watch folders and trigger processing
Direct API integrations with platforms (YouTube Data API, TikTok API, Holywater when available)
S3 / Cloudflare R2 + serverless functions for scale

Step 2 — Transcribe and auto-segment

Accurate transcripts are the foundation. Use an ASR with speaker separation and timestamps (e.g., AssemblyAI, OpenAI Whisper X, Rev.ai). For vertical episodic content — often 30s–5min — configure segmenting by topic or pause detection so timestamps map to discrete beats.

Run ASR to get full transcript with timestamps.
Auto-segment into topic chunks using a semantic model or silence detection (every 30–90s).
Label segments with auto-extracted topic tags (keywords) using NLP.

Store the transcript and segment JSON alongside the video. This becomes the single source of truth for show notes and SEO posts.

Step 3 — Generate raw show notes (prompt recipes)

Now feed the transcript + metadata into an LLM prompt pipeline that outputs: a short show notes blurb (50–120 words), detailed timestamp bullets, and a 1-line social caption. Use a two-pass prompt: first extract the facts, then rewrite into brand voice.

Raw extraction prompt (example)

Input: transcript segments JSON, episode metadata

Prompt: "Extract the episode title, 3–6 key topics, guest name(s), and 6 timestamped bullets (timestamp + 10–20 word summary) from the transcript. Return JSON with keys: title, topics[], guest, bullets[] (timestamp, summary), call_to_action."

Rewrite template — Show Notes

After extraction, apply this rewrite template to produce the public show notes:

<episode_title> — <subtitle>

  Quick Summary: <one-sentence summary>

  Key moments:
  - <00:00> — <moment 1>
  - <00:45> — <moment 2>

  Topics: <topic1, topic2, topic3>

  Listen / Watch: <links>

  CTA: <subscribe / follow / transcript link>

Use an LLM-controlled rewrite pass to enforce voice and length limits. Replace placeholders from extraction JSON.

Step 4 — Apply rewrite templates to preserve voice and avoid duplication

Rewrite templates are the secret to scale: they let you generate multiple, unique SEO variants (short show notes, medium blog summary, long-form SEO post) from the same transcript without duplicate content penalties.

Template set examples

Short show notes (60–120 chars): social-friendly blurb + link — ideal for cross-posting and the social layer
Long show notes (150–300 words): detailed summary + timestamps
SEO post outline (H2/H3 structure): head keywords and expanded paragraphs

Sample rewrite prompt (brand voice)

Instruction: "Rewrite the extracted show notes into our brand voice: concise, helpful, professional. Keep it under 180 words. Use active verbs and include the keyword 'show notes automation' once. Provide a 1-sentence CTA at the end encouraging readers to read the full transcript."

Step 5 — Convert episodes to SEO posts (podcast-to-blog recipes)

For search growth, convert each episode into a 800–1,500 word SEO post using the transcript as source material. The process is:

Auto-generate an SEO-optimized outline with target keywords for the episode.
Expand each outline node using the corresponding transcript segments (source quoting allowed up to a limit).
Insert relevant external links, time-coded embeds, and an FAQ section (generated from the transcript questions).

SEO post prompt template

System: You are an SEO editor (2026) focused on mobile-first vertical episode posts. Use E-A-T and avoid verbatim copying beyond 50 words per section.

User: "Given transcript segments and the topics array, create an SEO-optimized blog post (900–1,200 words) with H2s for each major topic, a strong intro (50–70 words), 3–4 supporting paragraphs per H2, a 5-question FAQ (derived from the episode), and a meta description. Use the keyword 'podcast to blog' in the first 100 words and 'vertical video' once in H2."

Step 6 — Quality controls, canonicalization, and human review

Automated output needs guardrails:

Run a plagiarism check or semantic similarity check between previous posts to avoid duplicates.
Flag sensitive content for human review (policy-based filters for defamation, medical/legal claims).
Apply canonical tags and hreflang where you republish across platforms.

Human-in-the-loop checkpoints can be lightweight: editors approve titles and CTAs, while LLMs handle the bulk of the drafting. Consider ephemeral AI workspaces for safe, auditable editor runs.

Technical integration: a practical stack (2026-ready)

Example stack to automate end-to-end:

Capture: Platform webhooks (YouTube/TikTok/Holywater) → cloud storage (S3)
Transcription: AssemblyAI / WhisperX (speaker separation, timestamps)
LLM pipeline: GPT-4o / Gemini Pro for rewriting (secure agent design)
Automation runner: n8n / Make / Airbyte for orchestration
CMS publishing: WordPress (WP REST API) or headless CMS (Contentful, Sanity)
SEO tools: Surfer/Frase or built-in content scoring using a vector search index
Monitoring: GA4, Search Console, and first-party analytics for watch-to-read conversion

Practical prompts and templates you can drop into your workflow

1) Transcript summarizer (compact show notes)

Prompt: "Summarize the following transcript into a 60–90 word show notes blurb that includes the episode title, three key takeaways, and a CTA to the transcript. Use the phrase 'show notes automation' once."

2) Timestamp generator

Prompt: "Create 6 timestamped bullets from these transcript segments. Each bullet should be 12–18 words and begin with a timestamp in MM:SS format."

3) SEO post expander

Prompt: "Using the outline below, expand into a 1,000-word SEO post aimed at content creators. Include internal links, suggested meta description, and three long-tail keyword suggestions." Use this for batch publishing and tie into your rapid edge publishing workflow.

Example automation recipe (batch process for 20 episodes)

Trigger: new video file uploaded to S3 (n8n trigger).
ASR: send file to AssemblyAI; store transcript JSON.
Extraction: run LLM extract prompt to get title, topics, bullets.
Rewrite: run rewrite templates to produce show notes, social caption, SEO outline.
Human check: editor reviews title and CTA (optional automated Slack notification).
Publish: post show notes to CMS + attach transcript JSON, schedule SEO post for next day.
Monitor: collect impressions, clicks, and watch-to-website conversions.

SEO and duplicate-content best practices

When repurposing audio/video into text, follow these rules:

Keep the transcript as a hosted asset but use canonical tags for multiple republished versions.
Ensure the SEO post adds value beyond transcript verbatim: analysis, resources, quotes, and an FAQ.
Limit verbatim transcript content per section (industry recommendation: under 50 words verbatim per 200 words of content).
Use structured data (PodcastEpisode, VideoObject) to help search engines index episodic content for rich results.

KPIs to measure automation ROI

Content output: number of show notes and SEO posts published per week
Time-to-publish: minutes from upload to published show notes
Search traffic: organic sessions to episode posts (30/60/90d)
Engagement lift: watch-to-site conversion rate, average session duration
Quality: editor rework rate (%) and user-reported issues

Troubleshooting common issues

Low transcript quality

Use better audio preprocessing (noise reduction, gain normalization). If ASR confidence is low, flag for manual correction or use human-in-the-loop captioning for critical episodes. Field gear and capture tips (mics, portable PA) can also help — see portable PA system reviews for practical options.

Duplicate content warnings

Audit similarity using sentence-level embeddings. If similarity > 0.85 to an existing post, trigger a rewrite pass focused on unique angles and additional assets (images, quotes, FAQ).

Voice drifting

Lock a brand voice prompt template and include 3–5 brand-approved example paragraphs in the LLM system prompt. Use a style score to detect drift and maintain consistency with brief templates.

Advanced strategies and future-proofing (2026+)

As LLMs and multimodal models evolve in 2026, apply these advanced strategies:

Vectorized episode memory: store episode embeddings to surface related episodes and auto-suggest internal links at publish time (embedding ops).
Conditional templates: generate different post lengths and CTAs depending on the platform (email digest vs. blog vs. Holywater page) and tie into your community commerce workflows.
Personalization: dynamically rewrite CTAs and social captions for audience segments using first-party data.
Adaptive SEO: use live SERP scraping to tune headings and keyword density at publish time (monitor costs).

Example mini case study (hypothetical)

Publisher X repurposed a 30-episode vertical series using this recipe. They automated transcription and show-note generation, applied rewrite templates, and published SEO posts that increased organic search traffic 42% in 90 days. Time-to-publish dropped from ~3 hours per episode to under 15 minutes, and editor rework fell to 12%.

Checklist before you launch your pipeline

Define metadata schema and storage location
Choose ASR provider and configure timestamps
Create 3–5 rewrite templates for show notes, SEO posts, and social copy
Set quality gates and human-in-the-loop thresholds
Integrate with CMS and analytics for monitoring

Final takeaways: Why this matters now

With mobile-first platforms like Holywater pushing serialized, AI-driven vertical content in 2026, publishers must automate the text layer that powers discovery. Show notes automation and robust rewrite templates are the scalable way to convert episodic vertical video into searchable, monetizable assets. The payoff is clear: more organic reach, faster publishing cadence, and preserved brand voice at scale.
