Create Perfect YouTube Thumbnails

Effective thumbnails make users click right away and make your YouTube channel more recognizable. Thumbnails should be relevant to the video’s content and title. Include short descriptions and relevant images in your thumbnails to help people understand what your video is about.
Catch the interest of people and tell a story using your thumbnails. You should make them wonder what happens next. Ideally, your title and thumbnail will tell a complementary story together. Make your thumbnail a cliff-hanger, basically.
