Best Practices for AI UGC
1. Disclosure and Transparency
Legal and ethical requirements:
- FTC guidelines: Disclose AI-generated content when it could mislead
- Platform policies: Instagram, TikTok, YouTube have AI disclosure requirements
- Consumer trust: Transparency builds long-term credibility
Best practice approaches:
Subtle disclosure:
- Small text: "Created with AI technology"
- Hashtag: #AIGenerated or #SyntheticMedia
Transparent approach:
- Explicitly state: "AI-generated testimonial based on real customer review"
- Behind-the-scenes: Show how AI content is created
Example:
Bad: AI testimonial presented as real customer without disclosure Good: "Real customer review, brought to life with AI avatar technology"
2. Authentic Voice and Messaging
AI UGC works best when:
- Scripts are based on real customer feedback
- Messaging matches brand voice
- Avatars represent actual customer demographics
- Content addresses real pain points
Process:
- Collect actual customer testimonials/reviews
- Extract key themes and language
- Create scripts using authentic customer language
- Generate AI videos that feel genuine
Example:
Rather than writing marketing copy, analyze 100 customer reviews, extract common phrases ("game-changer," "saves me 3 hours daily"), and use actual customer language in AI scripts.
3. Testing and Iteration
AI enables rapid testing:
Traditional: Create 1-2 video variations, test, iterate slowly AI: Create 50 variations in 2 hours, test simultaneously, optimize fast
Testing framework:
Variables to test:
- Avatar demographics (age, gender, ethnicity)
- Script hooks and messaging
- Video length (15s, 30s, 60s)
- Background settings
- Tone (casual, professional, enthusiastic)
Example:
DTC brand tests 20 UGC-style AI videos:
- 5 different avatars
- 4 different hooks
- 3 video lengths
After 48 hours: Find winning combination (avatar C, hook 2, 30 seconds), generate 10 more variations, scale winning formula.
4. Platform-Specific Optimization
Different platforms favor different content:
TikTok / Instagram Reels:
- 15-30 seconds max
- Fast-paced, energetic
- Captions required (sound-off viewing)
- Trending audio integration
YouTube Shorts:
- 30-60 seconds
- Educational or entertaining
- Clear value proposition quickly
LinkedIn:
- Professional tone
- 30-90 seconds
- Thought leadership angle
Facebook:
- Emotional storytelling
- 60-120 seconds
- Clear call-to-action
AI tools enable platform-specific versions:
Create master video, then use AI to:
- Reformat for different aspect ratios (9:16, 1:1, 16:9)
- Adjust pacing and length
- Modify tone and messaging
- Add platform-specific elements
