When creating a new Facebook cover photo, keep the following in mind:
Place text, images, and other elements to the sides of your cover image, balancing it out with your profile picture in the middle.
Try to integrate the elements on your cover photo with your profile picture, for example, by using the same color scheme.
Add calls to action to your cover photo, especially when advertising events or limited offers.
Use your Facebook cover to display brand-related elements, such as your slogan.
