TikTok rewards relevance. Punish mediocrity with 0.5-second swipes. Test before you burn budget.
Hook in 0–3 Seconds or Die
Upload three opening frames to Kettio. Synthetic Gen Z panel picks winners instantly.
Losing hooks: “Hey guys,” brand logo first, slow product shots
Winning hooks: text overlay question, jump-cut motion, creator face close-up
Creator vs. Brand Voice
Test same script both ways:
A. Brand account polished
B. UGC-style handheld
Kettio scores show 18–24 demo prefers handheld by 34%. Shoot accordingly.
Trending Audio Check
Drop three clips with different tracks. Synthetic audience flags which feels “forced.”
Rule: if they can’t hum it, don’t use it.
Caption Length Test
≤80 characters beats >120 by 28% with mobile-first viewers.
Kettio feedback: “Long text makes me swipe.”
CTA Placement
Free ad prediction

Last 2 seconds vs. persistent sticker. Test both.
Data: sticker lifts intent 0.6 pts, but only if caption is ≤12 words.
Vertical Frame Rules
9:16 full bleed wins; any border drops score 20%.
Test thumbnail separately—bright background + 3-word headline = highest click.

Morning: upload rough cuts
Afternoon: get scores & quotes
Evening: reshoot top performer
Night: launch with confidence
