# TikTok Video Performance Analyzer
## Purpose
Analyze TikTok video ad performance with a focus on hook effectiveness (first 2 seconds), video length optimization, and engagement patterns. On TikTok, **70% of video retention is decided within the first 2 seconds** - making hook analysis critical for success.
## The Critical 2-Second Rule
```

```
## When to Use This Skill
Invoke when user mentions:
- **Hook optimization:** "How do I improve my TikTok video hook?"
- **Length questions:** "What's the optimal video length for TikTok?"
- **Completion issues:** "Why is my video completion rate low?"
- **Content strategy:** "Should I use UGC or polished content?"
- **Ad format:** "When should I use Spark Ads vs regular ads?"
## Hook Analysis Framework
### Effective Hook Types
| Hook Type | Description | Example | Best For |
|-----------|-------------|---------|----------|
| **Curiosity** | Open loop, question, surprising statement | "You won't believe what happened when..." | Awareness |
| **Emotional** | Surprise, humor, shock, fear | "This made me cry..." | Engagement |
| **Value Promise** | Clear benefit stated immediately | "3 ways to save $1000 on..." | Consideration |
| **Pattern Interrupt** | Unexpected visual or audio | Quick cut, loud sound, visual glitch | Stopping scroll |
| **Native Format** | Looks like organic content | "POV: When you discover..." | Authenticity |
### Hook Health Check
| Rating | 2s View Rate | Action |
|--------|--------------|--------|
| **Excellent** | >70% of plays | Hook is working well |
| **Good** | 50-70% of plays | Room for improvement |
| **Needs Work** | <50% of plays | Prioritize hook optimization |

## Video Length Optimization
### Recommended Length by Objective
| Objective | Recommended Length | Reason |
|-----------|-------------------|--------|
| **Awareness** | 15-20 seconds | Maximize reach and completion |
| **Consideration** | 10-15 seconds | Balance engagement and attention |
| **Conversion** | 6-10 seconds | Quick CTA, lowest cost per action |
### Creative Specs (In-Feed Video)
- **Format:** 9:16 vertical, 1080×1920px
- **Max length:** 60 seconds (recommended 9-15 sec for best performance)
- **Audio:** Required — 93% of TikTok users watch with sound on
- **Safe zones:** 150px top, 175px bottom (avoid placing text/CTAs here)
### Completion Rate Benchmarks by Length
| Video Length | Expected Completion Rate |
|--------------|-------------------------|
| Under 15s | 76.4% |
| 15-30s | 65% |
| 30-60s | 50% |
| Over 60s | <40% (also exceeds platform max for In-Feed ads) |

STRENGTHEN HOOK SHORTEN BY 30% IMPROVE TARGETING
- New opening - Get to point faster - Check audience match
- Pattern interrupt - Cut middle section - Test different segments
- Add text overlay - Move CTA earlier - Review demographics
```
**Common Fixes for Low Completion:**
1. Strengthen first 2 seconds
2. Shorten video by 30% (max 60 sec; target 9-15 sec)
3. Add captions (7% watch without sound — but captions improve retention for all)
4. Test trending sounds (93% watch with sound — audio is a primary engagement lever)
### Low CTR Despite Views
**Diagnostic Questions:**
- Is the CTA clear?
- Is the CTA placed too late?
- Is the offer relevant to the audience?
**Common Fixes:**
1. Move CTA earlier in video
2. Add text overlay CTA
3. Use stronger action verb
4. Test "Shop Now" vs "Learn More"
### Low Conversion Despite Clicks
**Diagnostic Questions:**
- Does landing page match video?
- Is LP mobile-optimized?
- What's the load speed?
**Common Fixes:**
1. Ensure video-to-LP continuity
2. Simplify checkout/form
3. Use TikTok Shop for lower friction
## Optimization Recommendations
### Quick Wins (Implement Today)
1. Add text overlay in first 2 seconds
2. Test trending sounds/music
3. Add captions for sound-off viewing
4. Start with action, not logo
### Creative Tests to Run
| Test | Hypothesis | Metrics to Track |
|------|------------|------------------|
| Hook A vs Hook B (same content) | Different hooks affect retention | 2s view rate, completion |
| UGC vs polished version | UGC performs better | CTR, CPM, fatigue rate |
| 6s vs 15s vs 30s lengths | Shorter = higher completion | Completion rate, CPA |
| Spark Ad vs regular boost | Spark = higher engagement | Engagement rate, CVR |
### Campaign Type Considerations
| Campaign Type | Video Approach | Notes |
|---------------|---------------|-------|
| **Standard auction** | Any length ≤60s; hook critical | Manual control |
| **Smart+ Campaigns** | 9-15s recommended; algorithm selects best | Auto-optimization across audiences (like Meta Advantage+) |
| **Search Ads** (Sep 2025) | 9-15s; clear value prop in first 2s | Keyword-targeted; higher intent audience |
| **Spark Ads** | Matches original organic post length | Must feel native |
| **GMV Max / TikTok Shop** | 9-15s product demo; CTA = "Shop Now" | Automated Shop campaign |
### Advanced Optimization
1. Analyze top-performing organic for hooks
2. Use Creative Center for inspiration
3. Test creator collaborations
4. Implement Smart Creative for auto-optimization
5. For Smart+ Campaigns: let the algorithm test hooks — provide 3-5 variations at launch
