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 Rules
TikTok 没有独立标题字段。 只有 Caption（描述文案），即发布时的文字输入区。Caption 兼具标题和正文功能，前 80 字符决定信息传达效率。不要在 Agent 调用中传递 title 参数。
Caption Writing
| Rule | Detail |
|---|
| Max Length | 4,000 characters (as of 2025) |
| Recommended | 50-150 characters for best engagement |
| Visible | First ~80 characters before "more" truncation |
| Keywords | Place primary keyword in first 40 characters |
| Line Breaks | Use for readability — TikTok renders them |
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)

Algorithm Optimization
See → references/algorithm-guide.md
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
- Search-optimized content has longest shelf life
Completion Rate Tactics
| Position | Strategy |
|---|
| 0-1s | Pattern interrupt: unexpected visual/sound/text |
| 1-3s | Hook: promise value ("Watch till the end for...") |
| 3-10s | Deliver first value point quickly |
| Mid | Maintain tension: "But here's where it gets interesting" |
| Pre-end | Tease payoff: "The last one is the best" |
| End | Reward + CTA: deliver promise, ask for follow/save |
