Use a photo. A blank area in a profile picture can signal that you aren’t real or that you are sketchy. Always use a picture; however, steer clear of using a logo, unless it’s a company page. Show your face, so people feel an instant connection with you.
Use a current photo. You want people to recognize you when they see you in person. Do away with that perfect picture of you from 2010, and use one that you took in the past six months.
Make it all about you. Your pets, kids or spouse may be adorable, but your profile picture should focus on you. Additionally, don’t use group shots or images that highlight nature or architecture more than your face.
Keep it professional. Wear work-appropriate clothing, and don’t use a profile picture that shows you partying down at a bar or living it up at a concert.
Convey confidence. Keep your head straight and your shoulders square, and genuinely smile.
Watch how much you edit. “Beauty face” apps can make you look flawless but blurry. Your face should be in focus, and your features should be clear and sharp. Also, avoid using black-and-white photos as they can steal some of the vibrancy from your picture.
