To increase your chances of connecting, be yourself.
These are the kind of photos that work well:
Use your own pictures and let people see your face.
If you’re shy, choose a shot from behind. Accounts lacking personal photos attract significantly less Connections and get reported up to 3 times more often, which can lead to being blocked.
Pictures that illustrate your personal interests and hobbies can help you connect with more people.
Convey your personality in your profile:
In your About section, describe what makes you interesting. Members with completed About sections are much likelier to make Connections.
Be open and specific about your interests and desires. You’ll only attract what you’re looking for if you know what that is.
Don't be afraid to play around with your Search settings.
What’s best practice?
Be proactive and begin a conversation as soon as you connect with someone new.
