Convert a YouTube [CONTENT_TYPE] transcript into a natural, engaging, fully SEO-optimized article.\n\n🔽 INPUT DATA (variables)\n\nYouTube Transcript: {{ $json.content }}\nYouTube Video Description: {{ $('Get the most Viral Video').item.json.snippet.description }}\nPrimary Topic / Hook: {{ $('Get the most Viral Video').item.json.snippet.title }}\nTarget Keyword List: [TARGET_KEYWORD_LIST_PLACEHOLDER]\n(choose the best one as PRIMARY)\nInternal Links (optional): [INTERNAL_LINK_URL_PLACEHOLDER]\nLink to original video:https://www.youtube.com/watch?v={{ $('Get the most Viral Video').item.json.id }}\nAuthor Name: [AUTHOR_NAME_PLACEHOLDER]\n\n\n✅ TASKS\n\nRead the transcript + description and understand the plot.\nPick a PRIMARY keyword (exact phrase from list) that best matches the story.\nPick 2–3 SECONDARY keywords (variations/related from the list).\nWrite an engaging article (800–1000 words): conversational, [BRAND_TONE_ADJECTIVES], but factual; organize for SEO and readers.\nOutput ONLY valid HTML (no markdown, no schema, no HTML comments). Nothing else.\nSatisfy Technical SEO Checklist (below) and show all required elements.\n\n\n🧭 CONTENT STRATEGY\n\nHook first: Start with the [HOOK_STRATEGY] in ≤100 words, include PRIMARY keyword.\nContext: Who are the people (full names first mention), why it matters.\nFlow: Tell it like a story ([CONTENT_STRUCTURE_OPTIONS]). Use 2–3 specific H2s.\nQuotes: Paraphrase or quote brief impactful lines from transcript.\nAnswer user intent: [USER_INTENT_QUESTIONS].\nClose strong: Recap takeaway, tease related [CONTENT_CATEGORY] (internal link).\n\nTone: [BRAND_VOICE_DESCRIPTION]. Use words like [BRAND_SPECIFIC_VOCABULARY] when natural. Avoid fluff.\n\n🛠 TECHNICAL SEO CHECKLIST (MUST PASS)\n\nTitle (H1): 50–60 chars, PRIMARY keyword near start. One H1 only.\nMeta description: 150–160 chars, includes PRIMARY keyword, persuasive.\nSlug suggestion: short, lowercase, hyphenated; contains PRIMARY keyword (return it in a data-slug comment-less attribute on the <article> tag: data-slug=\"your-slug\").\nPRIMARY keyword placement: first 100 words, one H2, last paragraph (CTA), and once bolded.\nSECONDARY keywords: 2–3 sprinkled naturally (overall density <2%).\nSubheadings: H2 every ≤300 words; at least one H2 carries a SECONDARY keyword.\nReadability rules (aim to please Yoast/RankMath):\n\n≥30% sentences start with transition words (e.g., \"However\", \"Moreover\").\nPassive voice ≤10%.\nNo more than 2 consecutive sentences starting with the same word.\nParagraphs ≤150 words; avg sentence length ≤20 words.\n\n\nInternal link: ≥1 to my site with descriptive anchor (skip if none provided).\nExternal link: ≥1 authoritative source besides YouTube if possible; always include the original video with rel=\"nofollow\".\nTable of contents: simple <ul> with in-page anchors under a <nav id=\"toc\"> block.\nConclusion CTA: invite to [CTA_ACTION], reiterate PRIMARY keyword once.\nWord count: 650–950 words (stay in range if transcript is short).\nNo keyword stuffing: natural only.\n\n\nName Recognition Strategy:\n\nExtract all names from transcript, description and video title\nUse full names when first mentioned, then first names or nicknames. Avoid phrases like [AVOID_PHRASES_PLACEHOLDER]\nBuild character: Give readers context about who these people are in 1-2 sentences\nConnect the dots: Explain relationships between people involved\nTag relevant platforms: Mention their [RELEVANT_PLATFORMS] accounts when relevant\nActive voice always: \"[PERSON_A] called out [PERSON_B]\" not \"[PERSON_B] was called out\"\n\n📦 OUTPUT FORMAT (RETURN ONLY THIS)\n<!-- ====== START HTML OUTPUT ====== -->\n<h1>[TITLE with PRIMARY keyword]</h1>\n<meta name=\"description\" content=\"[150-160 char meta with PRIMARY keyword]\">\n<article data-slug=\"[your-slug]\">\n<p><strong>[PRIMARY keyword]</strong> … [intro hook ≤100 words]</p>\n<h2 id=\"sec-1\">[Subheading with a SECONDARY keyword]</h2>\n<p>...</p>\n<h2 id=\"sec-2\">[Names/platforms/context]</h2>\n<p>...</p>\n<h2 id=\"sec-3\">[Reactions/impact]</h2>\n<p>...</p>\n<p>Watch the original video <a href=\"\" rel=\"nofollow\">here</a>.

(No markdown, no explanations, no extra keyword highlights like \"**\".)\nValid HTML tags; no unclosed tags.\nNO MARKDOWN SYMBOLS ANYWHERE. DO NOT MARK INSERTED KEYWORDS WITH ANY SYMBOLS\nUse names and surnames whereever possible.\n\n\nNOTES\n\nIf transcript lacks names, use those in description/title; otherwise infer from topic but don't invent people.\nDon't be too formal. You write a blog about [CONTENT_NICHE], so the text must be [CONTENT_STYLE_REQUIREMENTS]\nNo defamatory claims: stick to transcript facts.\nIf any input is missing (e.g., internal links), skip gracefully but keep structure.",
