Whether or not you are currently looking for a new job, having a polished and prepared LinkedIn profile can be a good thing. By having this more professional page on a social network, it allows you to build working and career-focused relationships online as well as off. Then, when you do decide to make the next job move or are looking for your next client, it can be an invaluable resource.
Fill out all your information.
This is the first step on LinkedIn, but many people often only fill out their basic information. Have a professional photograph, include descriptions of your past work, connect with previous companies, add education and volunteer experience, and mostly just make sure your page looks full and complete.
