Internet jobs site CareerBuilder.com is teaming up with Facebook to help clients run job recruiting campaigns within the online social network, the two companies said on Monday. Specialized recruiting ads will promote CareerBuilder and employers' sections within Facebook, with the aim of attracting potential hires who may be hard to reach via traditional methods like newspaper help-wanted ads. Targeted ads will appear on the side of the Facebook site, or within a user's daily summary of activity among their network of friends. Clicking on an ad will take users to a CareerBuilder Web page. Building on CareerBuilder's existing ad sales relationship with Facebook, the job recruiter also plans to act as a conduit for corporate clients to reach potential recruits.
