What actually changes between variations?

The hook, pacing, editing style and call to action. The underlying idea stays fixed, which is what makes the comparison meaningful rather than just producing several different videos.

How many variations should I make?

Three to five per idea is usually enough to see a difference without saturating your own audience. Beyond that you are mostly re-testing the same thing.

How do I know which variation won?

Compare retention in the first three seconds for hook differences and completion rate for pacing differences. Raw view counts conflate the two and are also more sensitive to when you posted.

Will my audience mind seeing similar videos?

Spread them across days rather than posting them together, and vary the opening enough that the video reads as a fresh take rather than a repost. Platform distribution also means most followers see only a fraction of what you publish.
