The importance of a profile photo
If you don't define your image, others will do it for you
It doesn’t take a rocket scientist to understand that the first thing we see when checking out a new profile is the photo. And if the photo you present isn’t eye-catching, or illustrative of your personal brand, you may miss your shot at making a positive first impression.
First and foremost, your profile picture stands for your online identity of who you are. The basic essence of a Profile Picture is equal to proving ownership of a profile. There is a real person behind this profile.
Just choose one of many different types:
Professional or Casual
Real or Imagined
Kids or Pets
Brand logo, Clip Art, Artistic Expression.
You can say a lot about yourself by using a representative image instead of the obvious photographic choice. Don't waste your chance.
And you can say a lot by not showing one (unfortunately you are just leaving someone else to fill in the blanks. And usually that does not help).
