TikTok Product Videos for eCommerce: Best Practices (2026)
TikTok is now the #1 discovery platform for product purchases among under-35 shoppers. Brands with looping product videos in their TikTok Ads see 3–5x higher engagement than static image ads.
TikTok Video Specs for Product Ads
| Spec | Requirement |

| Format | MP4 or MOV |
| Aspect ratio | 9:16 (vertical) — required for best performance |
| Resolution | 1080×1920px recommended |
| Duration | 5–60 seconds (5–15s performs best for product ads) |
| Max file size | 500MB |
| Sound | Design for sound-off — most users watch without audio |
Why Looping Videos Perform Best on TikTok
- TikTok's algorithm rewards watch time and replay rate — loops score high on both
- A 5-second loop watched 4 times = 20 seconds of engagement
- Seamless loops feel native to TikTok's endless scroll format
- No abrupt ending means the algorithm doesn't penalize for drop-off
