"A YouTube banner is a picture that appears at the top of your channel and serves as a summary of your content. It's also known as channel art, and the concept is quite similar to Facebook's cover photo or header image. Because it is the face of your channel, an attractive YouTube banner must make a strong first impression.
The aesthetic YouTube banner exhibited in this sample is defined by peace, tranquility, bird singing, and the ideal natural setting. The banner is for travel suggestions, but it may also be used for camping, safari, off-grid solutions, and natural living YouTube channels. You can alter the graphics and content to fit your needs and make your banner more relevant, just like with any other design."
