What Makes a Good TikTok AI Video?

Regardless of the tool, high-performing TikTok videos usually share these traits:

1. A Strong Hook (First 1–3 Seconds)

Your opening line matters more than visuals.

2. Native, UGC-Style Visuals

Overproduced videos often underperform.

3. Captions and On-Screen Text

Most TikTok videos are watched without sound.
