Hiring managers tend to look for local candidates to fill job positions. If you're considering moving to a new place, make sure you change your LinkedIn profile to reflect the right postcode. Over at Avid Careerist, Donna Svei reveals that recruiters often restrict their LinkedIn searches by postcode. This means you'll never be found unless your location matches the one the recruiters are looking for.
It is a risk if your boss notices the location change on your LinkedIn profile, but a gamble that could pay off if you're thinking of moving. It's a strategy similar to leaving your address off your resume: You don't want your current location to restrict your job opportunities.
