A service segment of the Talent Acquisition Technology Industry. Job Boards are internet-based talent acquisition technologies that aggregate either local, national or international job offerings. In most instances, employers pay up-front to advertise these job offerings, which differs from the cost model of Employment Agencies that charge a fee only when a Candidate has been successfully placed. Job Boards sometimes refer to themselves as Job Portals or Career Portals. Newer variations on the traditional job board business model have more recently emerged such as those offered by social media giant LinkedIn, career communities, job aggregators (meta search job boards that aggregate job postings from other sites), and job distributors (platforms for hirers to advertise jobs on multiple syndicated Job Boards).
