1. Have a headline that is more than your job title. You have a few seconds to make the impression. Communicate more than your title/role.
2. Create your short url for your profile. It's easy, quick and worth it. https://www.linkedin.com/help/linkedin/topics/6042/6054/87
3. Update your 'primary' email that is visible to connections in your settings. Many times it's your personal address rather than work as your 'primary' and you do not want that to be the on people have access to use.
4. Use it well. It's not a sales platform but a relationship management resource. Respect people and their time. Value them.
