Mr. Beast discovered the easiest way to get longer watch times on YouTube. Here's a hint, it has something to do with his video thumbnails, and it actually seems to be working. It started with a YouTube experiment that MrBeast used to compare different thumbnail facial expressions. Here's version A and here's version B. Can you guess which thumbnail won? Believe it or not, it was the simple closed mouth version in thumbnail B. That's right, the age old shock face strategy used by youtubers everywhere actually lost. While MrBeast didn't share specific numbers for watch time or other metrics, did reveal the results of multiple AB thumbnail tests on X and they were the same every time. You know what this means, right? We're probably going to see everyone doing this from now on, and it's no surprise that.
