The thumbnail and the title of your video are the first two things that users see. Therefore, you need to be vigilant about these two things when uploading your video onto your channel. Avoid mediocrity by putting in necessary efforts for both these categories.
For the thumbnail, do not just randomly select any specific screenshot from your video. Your video thumbnail is perhaps the most influential element that will make a user click on your video. Thus, spend necessary time and effort on working on your thumbnail ideas, as it is often the first thing users see. Use editing apps such as Photoshop or Canva to create more appealing thumbnails, use bold text and contrasting colours to help your video catch the eyes of users.
The title you choose also plays an important role in the amount of interaction the video gets. Make your title compelling and interesting, and also keep in mind to ensure it provides search value. However, avoid resorting to click-bait under any situation. Your title should give your viewers a reason for them to click on your video. The more the number of users who click on your video, the more YouTube will recommend it. Add keywords into your title if necessary. Experiment with different titles to find the precise balance between being clever, adding keywords and providing value.
