How does it work?

We store all the thumbnails you upload. Every day at midnight PST or every hour, we change the thumbnail on your chosen video to the next thumbnail in the list. At the end of the test, we look back at the click-through rate each thumbnail got and use that to calculate which thumbnail performed the best. That thumbnail (or title) is marked the winner.
