Indeed, your résumé, LinkedIn profile and bio are such critical elements of your job search that if you haven't perfected all three of them, you may never land a new job. That's why, if , you may want to refocus your efforts on these three key elements.

Here, Macpherson explains the unique role that your résumé, LinkedIn profile and bio play in your job search, how they complement each other, and how IT executives can make them sing to recruiters and prospective employers.

"The résumé is still the number one job search currency out there," says Macpherson. "No matter how you get in front of a potential opportunity, at some point, everyone wants to see a résumé, and it has to be spectacular, especially at the senior level."

When you write or update your résumé, instead of thinking structurally--that is, contact information goes here, experience goes here, education goes here--Macpherson advises his clients to think strategically, in terms of their target audience. What's important to them? What do they need to know about your experience? When you start thinking about their needs, you're better able to sell them on your value, says Macpherson. "It does make a difference," he says. "It's worth investing the time to get it right."
