While recruiters have much to offer job seekers, job seekers have much to offer recruiters. Referrals are recruiters' bread and butter; passing along the names of qualified peers will definitely improve and extend your relationship with a recruiter, whether you are a fit for a current job or not (and may benefit a job-seeking colleague at the same time). "If there is one thing a recruiter loves, it is getting names of good people they can place," said Tony Deblauwe, founder of consulting firm HR4Change. "If you aren't interested or a fit when a recruiter calls, offer to give them names. Over time, you will get called again, and the gesture of giving referral puts you in front for future opportunities."
