Under the "Contact Info" area, LinkedIn allows you to have up to 3 websites listed, your email address and your Twitter account.

Most people have boring link titles (default is 'My Website'). Make sure yours are more like call to actions, something a little more intriguing.

You can do this by going into the edit mode, clicking "edit contact info" and the clicking on the little pencil right next to the website link which will pull up a small box where you enter the three links, the type of site, and the url. The trick here is to make sure you pick other and add a few words that will make the link sound interesting.
