TikTok Content Creation

Caption Style

Core Tone: Authentic, Hook-first, Trend-aware

• Authentic: Sound like a real person, not a brand. Casual, conversational
• Hook-first: First line must stop the scroll — 1-2 seconds to capture attention
• Trend-aware: Reference trending sounds, formats, and cultural moments
• Value-driven: Every video must deliver on its promise
• Inclusive: Write for global audiences — simple English, avoid regional slang overuse

Caption Templates

Hook + Value + CTA:
  "POV: you just discovered [hack/trick/fact]"
  "Stop scrolling if you [pain point]"
  "3 things I wish I knew about [topic] sooner"
  "This [method] changed everything for me"
  "Nobody talks about this but [insight]"

Story-driven:
  "I tried [X] for [time] — here's what happened"
  "Day [N] of [challenge/experiment]"
  "What I learned from [experience]"

Engagement bait (compliant):
  "Save this for later"
  "Share with someone who needs this"
  "Comment [emoji] if you agree"
  "Which one are you? 1, 2, or 3?"

Writing Rules

DO:
  - Start with a hook (question, bold claim, or relatable scenario)
  - Use line breaks for readability
  - Include 1 clear CTA (follow, save, share, comment)
  - Write in first person where possible
  - Use numbers for specificity ("5 tips" > "some tips")
  - Match caption energy to video energy

DON'T:
  - Start with "Hey guys" or "Welcome back" (wastes the hook)
  - Write walls of text (keep under 150 words in caption)
  - Use all caps excessively (looks spammy)
  - Promise what the video doesn't deliver (reduces retention)
  - Use banned/restricted words (see content-rules.md)
  - ⛔ Insert ANY external URLs in caption (GitHub, website, shop links, etc.)
  - ⛔ Put QR codes in video frames
  - External links ONLY allowed in Bio — use "Link in bio" to redirect

Caption Writing

Caption Formula

[Hook line — grab attention]

[Value/Content summary — 1-2 sentences]

[CTA — follow, save, share, or comment prompt]

[Hashtags — 3-5 relevant tags]

Example Captions

Tutorial:
  "The Excel trick your boss doesn't know about 👀
   This saved me 3 hours every week.
   Save this & try it tomorrow.
   #ExcelTips #Productivity #WorkHack #LearnOnTikTok"

Storytelling:
  "I quit my 9-5 to build an app. Month 3 update.
   Revenue: $0 → $4,200. Here's exactly what I did.
   Follow for month 4 🔔
   #BuildInPublic #StartupLife #Entrepreneur"

Trend/Entertainment:
  "Tell me you're a developer without telling me 💀
   Comment yours ⬇️
   #DevLife #ProgrammerHumor #Tech #fyp"

Hashtag Strategy

Hashtag Best Practices

Count: 3-5 hashtags (sweet spot for reach)
Placement: End of caption (keeps caption clean)
Mix:
  1 broad/discovery tag:  #fyp #foryou #viral
  1-2 niche/topic tags:   #CodingTips #StartupLife #AITools
  1 trend/challenge tag:  Current trending hashtag
  0-1 branded tag:        Your own recurring tag

Max: TikTok allows up to 100 characters for all hashtags combined

High-Performance Tags

Discovery:
  #fyp #foryou #foryoupage #viral #trending

Engagement:
  #LearnOnTikTok #TikTokMadeMeBuyIt #tutorial

Niche (examples):
  Tech: #TechTok #CodingTips #AI #WebDev
  Business: #SmallBusiness #Entrepreneur #SideHustle
  Finance: #MoneyTok #Investing #CryptoTok
  Lifestyle: #LifeHack #Productivity #Motivation

Avoid:
  - Banned/restricted hashtags (check before using)
  - Irrelevant trending tags (algorithm penalizes mismatch)
  - Too many tags (>8 looks spammy, dilutes signal)

For You Page (FYP) Ranking Signals

Weight (estimated):
  1. Watch Time / Completion Rate — #1 signal, videos watched to end get boosted
  2. Re-watches — Users watching again = strong positive signal
  3. Shares — Highest-weight engagement action
  4. Comments — High-weight, especially lengthy ones
  5. Saves/Favorites — "Bookmark" indicates high-value content
  6. Likes — Base engagement, lower weight than above
  7. Profile Visits — from video = interest signal
  8. Follow-from-video — Strong conversion signal

Content Lifecycle

Phase 1: Initial Push (0-1h)
  - Shown to 200-500 users (small test pool)
  - Algorithm measures: completion rate, engagement rate
  - Target: >50% completion, >5% engagement

Phase 2: Expansion (1-24h)
  - If Phase 1 metrics pass threshold → 5K-50K pool
  - New signals: share rate, comment quality
  - Target: maintain engagement ratios

Phase 3: Viral Potential (24h-7d)
  - Strong Phase 2 → 100K+ pool
  - Content enters broader FYP
  - Can continue growing for days/weeks

Phase 4: Evergreen (7d+)
  - High-performing content resurfaces periodically
