Tips for TikTok Performance
Hook viewers in the first 2 seconds — TikTok's algorithm prioritizes completion rate.
Shoot vertically at 9:16 from the start — rotating footage loses quality.
Use trending sounds — TikTok's recommendation system favors videos using popular audio.
Keep text in the center safe zone (avoid bottom 300px — navigation bar area).
Export audio at 192 kbps minimum for clear sound on all devices.
