Having your site shown on your LinkedIn profile and sharing your content with your Linked in followers are just two ways that could increase traffic. Another way of getting your content viewed is through LinkedIn Groups. At LinkedIn you can join a number of groups where people discuss topics related to your niche. As a group member you can start discussions featuring a relevant links to your content, asking other members for their opinions. Many of them will click the link to view the content before commenting. The best results will obviously come from big-membership groups based around topics that give their members plenty to discuss. Interacting in groups will also help to build your reputation and get more followers. I'm not sure if discussion posts that are linked to your content count as high PR backlinks, but they certainly will not harm your ranking by drawing attention to your content.
