Include only relevant job positions on your Facebook profile.
Hiring companies and recruiters will often determine whether you are a good fit for a position based on your relevant, past experience. For example, when looking for a new job in computer programming, list your last 2 or 3 programming positions instead of positions related to your previous experience at a fast food restaurant.
Upload and use a professional photo of yourself.
The users you network with will use your photo to form a first impression of you. For example, upload a photo of yourself wearing business casual attire, instead of a photo of yourself on summer vacation at the beach.
