The TikTok AI UGC Formula

The 3-Second Rule

You have 3 seconds to hook viewers or they scroll. Period.

Winning Hook Patterns:

1. Pattern Interrupt

"Stop scrolling, I need to tell you..."
"POV: You just discovered..."
"Wait for it... this is crazy"

2. Bold Statement

"I spent $500 on [product category] and this was the only one that worked"
"This $20 product does what $200 products can't"
"Nobody talks about this hack but..."

3. Relatable Problem

"If you struggle with [problem], you need this"
"Me trying to [common struggle]..."
"When you finally find a solution for [pain point]"

4. Visual Hook

Unexpected scene or action
Before/after immediate comparison
Surprising product demonstration
Emotional facial expression

The 30-Second Structure

Seconds 0-3: HOOK Pattern interrupt that stops the scroll

Seconds 3-8: PROBLEM Agitate the pain point "You know how [common frustration]?"

Seconds 8-15: SOLUTION Introduce your product naturally "I found this [product] that..."

Seconds 15-25: PROOF Show it working or share results "Look at this..." or "After using it..."

Seconds 25-30: CTA Simple, direct next step "Link in bio" or "Shop now"
