Careful A/B testing copy
Pre-publish thumbnail A/B voting, not official YouTube split testing
ThumbBattle lets you compare thumbnail variants before publishing by previewing them in context and collecting votes from people you trust. It does not split real YouTube traffic, change live thumbnails, or claim statistical certainty.
Use it for
- Choosing between 2-4 thumbnail directions.
- Getting client or community feedback through one link.
- Checking whether a title and thumbnail work together at feed size.
