Think about the situation that follows. You're searching YouTube for a video showing you how to tie a tie. You are presented with a list of videos when you click the search button. You pick the third video and start watching it right away. You'll see that the designer hasn't mentioned the main subject—tying a tie—even after watching the video for one minute. Will you keep watching the video? No, you're right! But you must be aware of this. If you sit and bore your viewers with unnecessary details, there's a strong chance they won't watch the video. Or, even worse, sign up for a subscription.

If you want to grow your YouTube account, make sure to take care of your YouTube video thumbnails. Why? Isn't it your intention that people watch your video? If you don't have a thumbnail or it's not good quality, you won't be able to grow.

YouTube will determine that your content isn't informative enough if your video doesn't receive enough views. As a result, the algorithm won't push the video up the results, which will limit organic traffic and, in turn, the rate at which subscribers are growing. By now, you must have realised how important the thumbnail is for attracting people to click on your video.
