Pre-Promotion Day: Capture the Sale Season 3-4 Days Before It Gets "Hot", No Need to Wait for the Main Event

If you only turn on Promotion Day on the actual sale day, you are missing out on the phase when customers start to “warm up” a few days prior. Pre-Promotion Day is the official extension that addresses this exact gap.

Comparing Pre-Promotion Day with Promotion Day

Category	Pre-Promotion Day	Promotion Day
Duration	Lower ROI, more aggressive budget, usually extended by 3-4 days before the existing Promotion Day schedule, fixed schedule cannot be changed	According to the existing promotion day schedule
Voucher	Additional TikTok Shop vouchers that customers cannot get otherwise, valid throughout the subsequent peak period	No additional TikTok Shop vouchers
Promotional Creatives	Select creatives for prioritized delivery — faster discovery, higher conversion, available for LIVE GMV Max as well	None

How to Set Up

Go to “Advanced Optimization” (same place as Mega LIVE), which is OFF by default. Turn on “Include pre-promotion phases” under the existing Promotion Day edit section. Then go to “Manage promotional materials” to specify prioritized promotional videos: for Product GMV Max, turn on the new “Promotional video”; for LIVE GMV Max, turn on the existing “Prioritize”. Select up to 10 promotional videos each time, and you should refresh these videos for each shopping season.
