Why Thumbnails Matter
- Your thumbnail is the first impression viewers get of your content.
- It often decides whether someone clicks or scrolls past your video.
- A great thumbnail should be clear, bright and high quality.
- It should catch the eye and tell your story instantly.
- Engaging thumbnails can increase your click through rate and boost your views.
