Back in the olden days, people searched the classified ads for jobs and mailed in a resume. The tech-savvy folks would fax their application. Managers knew where to post their open jobs, and they all went in the local paper.
But now there are dozens of national online job boards, flanked by niche job boards dedicated to industries, regions, or functional areas. You can even post ads on social media sites like Facebook, Google+ and LinkedIn. Anyone who mails in a paper resume just seems quaint and old-fashioned.
Posting your job ad on the wrong site will keep it from being noticed by the right people.
But how do you know where you should post it? With so many choices, how do you find out where the right people are currently looking for jobs?
