On your LinkedIn page, above and to the right of your head shot, is a large rectangle, known as your background image. The default option for this image looks like the night sky — a blue background with stars in constellations.
Instead of retaining this default option, you can make this large space work for you by inserting content that reinforces your “brand.” It’s a great way to help a reader see you the way you want to be seen. The custom background “can make your profile stand out and put itself in a category of one,” said William Arruda, who Entrepreneur Magazine dubbed the “personal branding guru.”
