If you want opportunities to come your way, you have to let people know you are open to them. It's so simple. Take LinkedIn.

Recently I was giving someone what I call a LinkedIn makeover, in which I rewrite the entire profile, tweak the headline, upload a cover photo, add missing information, and check settings. This person would like a new job, yet her notification to recruiters -- the button that lets recruiters know who the job hunters are -- was turned off. I turned it on. Within minutes she had a message from a recruiter, within a few days she had a phone interview, and within a week she had an in-person interview. Should this work out, I feel like I deserve a job-finder's fee. 

Here are three things you need to put yourself out there to recruiters and make sure you get messages from them and others who can help you land your next great gig.

1. Turn on notifications to recruiters.

On your profile page, look at your dashboard. Find the section called "Career Interests" and click on it. From there you have a lot of options. At the very least, you'll want to click the "Let recruiters know you're open" radio button to "on." You can choose to get contacted by phone. You also can let recruiters know your interests and job titles that interest you.

2. Let recruiters know how to find you.

I can't tell you how many times I've corrected clients' email addresses and phone numbers. Your contact information is high up on your profile page -- to the right of your photo and just below your company and college. In other words, it's prominent. And it takes just seconds to update, so do it or risk recruiters sending emails you'll never see.

3. Make sure recruiters can reach you within LinkedIn and that you know about it. 

Check your messaging notifications and preferences to make sure people are able to send you InMail (LinkedIn's name for the notes sent within the platform). You'll also want to set your notifications so that you'll get emails telling you things like when you have LinkedIn messages.

You wouldn't send a resume without your correct contact information. You wouldn't knowingly block a call or email from someone who wants to hire you or talk about a wonderful new job. Likewise, you want to make sure your LinkedIn profile is doing its most basic job: Letting the world know you're out there.
