CEOs are slow to post their profiles on LinkedIn, according to research by CTPartners Executive Search Inc. (NYSE MKT: CTP). Only 7 percent of Fortune 500 CEOs in the U.S. post profiles on LinkedIn. The CEOs who do post their profiles on LinkedIn indicate that they are more interested in expertise requests, business deals, reference requests and getting back in touch, rather than in job inquiries or career opportunities.

“The findings suggest that CEOs of very large, primarily non-tech firms are not buying into the importance of social media generally, and LinkedIn specifically,” said CTPartners CEO Brian Sullivan. “Their firms are almost certainly adopting social media strategies, but personally, CEOs aren’t yet seeing the value.”

CTPartners, a New York-based executive search firm, operates 23 offices in 15 countries. For the survey, the firm selected companies from three regions on Fortune’s 2012 Global 500 list including 131 from the United States.
