Search results in LinkedIn are also based on your connections. So while it is important to make a lot of connections, you don’t want to spam people. (Don’t connect with people just for the sake of having a lot of connections. That’s like giving your business card to everyone at a party.)
Look at other LinkedIn profiles for folks who have your same job title. See what they’re including in their profile that is getting them ranked highly using LinkedIn’s search algorithm.
