Make sure you are focusing on high-impact efforts like networking versus job board submissions.  Keep a record of your efforts so if an employer calls, you can quickly determine when and how they were contacted.

Recruiters read hundreds of resumes on a daily basis. They only have time to skim the top of them, so if you don't give a clear message about what you can do for them, then it is not a good resume. Since this is the most important document in your career, you need to give it the attention it deserves.

Start by selecting your bucket list of companies where you would love to work. Do a company search on LinkedIn and identify the decision-makers and their staff.  Then, see who you know who might know someone who can then make an introduction for you. Follow the company and

connect with people on LinkedIn, join their groups and conversations, comment on their blogs, and become known.

If a recruiter was searching through LinkedIn to find people for the position you are seeking, would you show up?  Try it and if you are not on the first or second page, go back to your profile and optimize it with the right keywords to get yourself a higher ranking.
