...don't put too many slideshow ( some profile have a 2 to 3 slideshow, the worst some of the pictures are the same with each other) ...don't use video as your background music ( some users use youtube or whatever video to play their favorite song in their profile ) ...don't put too many videos in your profile ( like others said not all of your friends and viewers watch your videos) ...put something about you on your about me section ( the purpose for that section is to know more things about you so don't put images glittery text and thumbnails of images in that section) ... and lastly, please don't put too many applications in your profile ( it is too irritating to see a profile that is full of applications, it takes time to load and makes the profile deeper, it makes a profile messy too)
