Frequently Asked Questions

What makes a good TikTok hook?

You have 1-3 seconds to stop the scroll. Best hooks: bold statements ('I made $10K doing this...'), questions ('Why does no one talk about this?'), controversy, relatable scenarios, or showing a surprising result in the first frame.

What is the best length for a TikTok video?

TikTok's sweet spot is 21-34 seconds for algorithm favor. YouTube Shorts under 60 seconds. Instagram Reels 7-15 seconds for highest completion rate. Our generator adapts scripts to your selected duration.

What is the Hook-Bridge-CTA video structure?

Hook (0-3s): Stop the scroll with a strong opening. Bridge/Value (3-50s): Deliver your content or story. CTA (last 3-5s): Tell viewers what to do next (follow, comment, share, check link in bio).

How do I find trending audio for TikTok?

Check TikTok's Discover page and 'For You Page' for trending sounds. The TikTok Creative Center shows trending audio by country. Our tool provides static tips on finding and using trending audio effectively.

Can I use these scripts for multiple platforms?

Yes, but adapt for each platform. TikTok prefers authentic, fast-paced content. YouTube Shorts can be slightly longer. Reels favor high-quality visuals. Our tool generates platform-specific versions of each script.
