An important aspect of your profile is keeping it up-to-date and accurate. You need to continually review and refresh your profile, photos, connections and skills. Make sure that your contact information is up-to-date, so that potential customers can reach you or want to work with you. Along with including your email and phone number, you also want to include your web address, Facebook page, Twitter handles, and other communication avenues that you use.
You want to make sure that your personal and company profiles are kept separate. Company and Showcase pages are free on LinkedIn and have customization options and distinctive features for your company.
