We store all the thumbnails you upload.
Every day at midnight (or every hour throughout the day), 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, views, and other stats each thumbnail got, and give you that data to decide which thumbnail performed the best.
Normally, an A/B test is when you show 100 people something, 50 see A and 50 see B, then you judge if A or B is better based on their reactions.
Therefore, a thumbnail A/B test means we show thumbnail A for one day/hour, then thumbnail B for one day/hour, and repeat that for a couple weeks.
At the end, we see which thumbnail more people clicked on.
1. Pick a video
2. Upload your thumbnails/titles
3. Hit "start"
Then, just wait until the test is over. That's it!
