Your profile score is based on how much of your profile you have completed. This score will be judged on the information in your ‘About Me' section, having a clear picture uploaded and being ID verified.
Profiles with a high profile score attract the most interest, so be sure to provide as much information as possible. This is YOUR time to shine so be sure to include the things which really highlight what kind of person you are. After all, would you message someone who had an empty profile?
