MrBeast fans don’t like his mouth open in thumbnails

In a post on September 6, 2023, MrBeast revealed that he was using YouTube’s thumbnail tester to see which facial expression influenced the most views on his videos and he found out fans don’t like it when his mouth is open.

“I closed my mouth on all my thumbnails and the watch time went up on every video lol,” he said. “My mouth is now closed in all my thumbnails but the war has just begun. We must not rest until mouths are closed in everyone’s thumbnails”

We’ll have to wait to see if he shares more about the thumbnail tests in the future, but in the meantime, head over to our entertainment section for more news and other viral stories.
