The Facebook Ad Hook Formula (That Converts)
🎣 0–3s: Pattern Interrupt
- “Stop buying [product] until you see this.”
- “I wasted $200 on alternatives. This fixed it.”
- “POV: You finally found a [solution] that works.”
💡 3–12s: Problem → Quick Proof
- Show the frustration visually
- Introduce your product as the fix
- Add micro-social proof (“50k+ sold”, “Rated 4.9/5”)
✨ 12–25s: Transformation + CTA
- Before/after or live demo
- Clear next step: “Tap Shop Now”, “Get 20% Off Today”
