As a recruiter I receive A LOT of resumes. It is so much easier to pick up the phone and work hard to present someone to one of my clients if I know there are people that recommend them.
Everyone has a list of references. People you can count on to stand up for your experience when they are called. LinkedIn brings a new light to that process. When someone recommends you on LinkedIn it is displayed on your profile page. Prospective employers feel a sense of ease when they realize your past co-workers actually appreciated your work. What makes LinkedIn the best way to display those accolades is the ease of access. We are all sitting in front of a computer and a website is the easiest way to collect info.
Long story short. Send out some requests for recommendations on LinkedIn and build that profile. It is one of the best tools we have today in proving you are right for the job you want. Add the link to your resume and BINGO = you have created interest.
