What makes a TikTok ad work
TikTok punishes anything that looks like an ad. The creative that wins is native, vertical, and hooks in the first second. For a Shopify product that means:
- Full-screen 9:16 (1080×1920) — a repurposed square feed ad underperforms here.
- A hook in the first ~1s — the problem, the result, or a pattern interrupt, before anyone scrolls.
- Sound-on, casual — a product demo or UGC-style clip beats a polished brand spot.
The structure that converts
- Hook (0–1s): the outcome or the objection. "I stopped my desk wobbling in 10 minutes."
- Show (1–8s): the product doing the one job, fast.
- Proof (8–12s): a specific detail — a number, a before/after.
- CTA: one clear next step.
You still need volume
TikTok creative fatigues faster than any other platform — you'll refresh constantly. That means producing many variations, not one perfect clip. How many creatives to test →
