You Need a Broad Network. Search on LinkedIn is limited by the size of your network, or 6 degrees of separation. When I look up a company and only have 3rd degree connections into the company, I know it is my lack of effort in reaching out to more people. You are in control of the quality of your search.
Be More Generous. Your Likes, Comments, Shares contribute to the newsfeed of your network. When you participate in your network you improve communication for everybody. If you watch a video and it is interesting, your Like or Comment will make it more likely for someone else to interact with that content as it stays in more newsfeeds longer. Improve the newsfeed and create positive business engagement with small actions every day.
Use The Mobile App. The LinkedIn mobile app is a convenient way to post an update, check your newsfeed, look for a contact or even a job. Your phone is one of the most powerful tools you have, use it.
