If you’re marketing in the B2B space, one way to make LinkedIn work harder for you is to start a group. Ideally, your group would attract the kind of people you want as clients or customers, so consider it’s name carefully what terms would your prospects use to search for such a group? Start conversations. Provide helpful content. Include your group’s badge in your e-mails and on your website. Share your group’s conversations across other social media like Twitter. The more engaged you are, the more engaged group members will be, and the more credibility you’ll gain.
