How to test product video ads before you spend
A simple way to test several product video ads on TikTok, Instagram and YouTube Shorts, one change at a time.
Testing ads is the only reliable way to know which one works. The mistake most people make is to change too many things at once.
Test one change at a time
Make a few versions of the same video, each with one change: a different person, a different setting, or a different first second. Then compare the results.
Use vertical formats
TikTok, Instagram Reels and YouTube Shorts all use vertical video. Make sure each variant is in that format before you upload it.
Decide before you look
Set the metric you care about, and how long you will let each variant run, before you start. That avoids choosing the winner after the fact.
Doppel makes the variants from one clip and your product photos: product video ads.
