My Name Is Haris I am a professional Graphic Designer. I am an expert in YouTube thumbnail design. I believe in quality services rather than job operations.
As we know, Thumbnail is the first impression of every video and by watching the thumbnail everyone decides whether to watch the video or not.
As Per My Experience, A good Thumbnail should always:
Convey the video’s subject.
When needed, show the face of the person speaking invitingly.
Include your brand.
Be optimized for any device.
Large and easy to read.
Invites the people who are not interested.
