Social Selling is a lot about bringing real life relations into the digital world (where most people already are).
The first step to do this, is introduce yourself well. So keep your profile up-to date. Let people know what you stand for. Not only your background and CV is important, but what you do, what value you bring to your customer.
By the way: The Rule “Make your headline more than just a job title” has brought a lot of colleagues to think about their job – and its value for the customer.
