/social-captions — Algorithm-Optimized Social Media Captions (v2)

The user sends material (text, image, script, competitor post, screenshot, or description of content). You analyze it and immediately generate captions for ALL 7 platforms in English.

No questions. No menus. Just analyze and deliver.

WORKFLOW

STEP 1: Analyze the Input

Read/view whatever the user sent:

• If it's text/script — extract the core topic, key message, niche, and tone
• If it's an image/screenshot — describe what you see, identify the niche and key message
• If it's a competitor post — analyze their approach, then write BETTER captions
• If it's a brief description — expand it into full captions

Write a short (2-3 sentence) analysis:

**Topic:** [what this is about]
**Niche:** [industry/category]
**Key message:** [the core idea to communicate]

STEP 2: Generate Captions for ALL Platforms

Generate captions for all 7 formats below. Each caption must use a DIFFERENT formula. All captions in English only.

Output in this exact format:

PLATFORM RULES (CRITICAL — follow exactly)

INSTAGRAM REELS

• Length: 80-200 characters. Short hook = video title
• Structure: Hook (first 125 chars before truncation) → 1-2 sentences max → CTA
• Hook: Must stop the scroll in 5-10 words. Use: conflict, transformation, curiosity gap, bold statement, or shocking stat
• CTA: Optimize for DM shares ("send to a friend who...") or saves ("save for later") — 10x more valuable than likes
• Hashtags: 3-5 niche hashtags IN the caption. Never #fyp, #viral, #instagood, #like4like
• SEO: Primary keyword in first 2 sentences
• NO: Engagement bait, emoji in first line, generic phrases

INSTAGRAM CAROUSEL

• Length: 300-900 characters. Longer captions work — users are already engaged
• Structure: Hook → Expanded value complementing slides → Save CTA
• CTA: Always optimize for saves. Carousels with save CTA get +68% saves
• Body: Lists, step-by-step, checklists. Structure with emoji-bullets or numbers

TIKTOK

• Length: 100-300 characters. First 80-100 visible before truncation
• Structure: Hook (80 chars) → 1-2 short sentences → CTA + 3-5 emoji (+33% engagement)
• SEO: voiceover > on-screen text > caption > hashtags in importance
• Keywords: Primary keyword in first 80 characters
• Hashtags: 3-5 MAX. Formula: 1 niche + 1 thematic + 1 trending. NEVER #fyp, #foryou, #viral
• Completion rate: 70%+ needed for viral. Caption should tease "watch till end"
• CTA: Questions get +44% comments

THREADS

• Length: 100-280 characters optimal (max 500)
• Structure: One clear idea. Conversational tone, like a group chat
• Tags: Only 1 topic tag per post. Can be multi-word. Niche > broad
• Engagement: Replies are #1 signal. Provoke conversation
• Links: +17% better with links now
• NO: Engagement bait, copy-paste from other platforms

FACEBOOK (Page/Personal)

• Length: 40-80 characters for max reach
• Structure: Ultra-short hook → value → discussion question
• Hashtags: 0-2 max or none
• AVOID trigger words: "buy now", "limited time", "FREE" (caps), "click here", "money", "income", "contest", "giveaway"
• SAFE replacements: "available today", "complimentary", "no cost", "learn more"
• Trigger word impact: 1-2 words = -20-30% reach, 3-5 = -40-60%, 6+ = -70-95%

FACEBOOK GROUP

• Length: 200-500 characters. Longer, contextual
• Reach: 30-50% of members (vs 1-2% for Pages)
• Style: Community language ("who else has experienced...", "curious what you all think about...")
• CTA: Open discussion questions

YOUTUBE SHORTS

• Title length: 40-70 characters optimal (max 100). Title is the #1 SEO signal — treat it like a search headline
• Title structure: Primary keyword first → benefit or curiosity gap → NO clickbait that misleads (YouTube penalizes)
• Title formulas: "[Keyword]: [what viewer gets]" / "How to [result] in [time]" / "[Number] [topic] secrets" / "Why [common belief] is wrong"
• Description length: 150-300 characters. First 100 chars visible before "Show more" — front-load the hook
• Description structure: Hook sentence (repeats/expands title) → 1-2 sentences of value → CTA → hashtags
• Hashtags: 3-5 MAX, placed at the end of description. 1 broad category + 1-2 niche + 1 topic-specific. NEVER #shorts as the only tag
• SEO: YouTube is a search engine. Match exact phrases people type: "how to use Claude", "AI productivity tips", "Claude tutorial"
• CTA: Subscribe prompt or "watch [linked video] for more" — channel growth > likes for Shorts
• Completion rate: Critical metric. Title must match video content exactly or retention tanks
• NO: Misleading titles, keyword stuffing, #shorts #viral #fyp as primary tags

ANTI-PATTERNS (NEVER do these)

Engagement bait (-50-90% reach on ALL platforms):

• "Like if you agree" / "Comment YES" / "Tag 3 friends"
• "Share before they delete this" / "React with [emoji] if..."

Shadow ban triggers:

• Violence words (even in innocent context)
• Adult content words
• Financial promises: "guaranteed income", "get rich quick"
• Letter substitution does NOT help — algorithms detect it

Format crimes:

• Same hashtags on every post (spam flag)
• More than 5 hashtags (limit since late 2025)
• Wall of text without line breaks
• #fyp, #foryou, #viral — useless and harmful
