Point weights are our own estimate built on TikTok’s guidance; TikTok gives no single best ad length. Always A/B test 3–5 creatives.
How the TikTok ad creative score works
Ten checks from TikTok’s guidance
TikTok recommends 9:16 at 720p or higher, sound, captions, people on screen, the proposition within 3 seconds, the hook within 6 seconds and a clear CTA.
Weighted score
The hook and 9:16 format weigh most, then sound, captions, CTA and people. Each missing item lists the points you would gain.
Test several versions
TikTok suggests 3–5 creatives per ad group, each clearly different, and refreshing them when results drop.
