According to a Jobvite annual survey released this morning, 92% of human resources and recruiting professionals use, or plan to begin using, social media for recruiting in 2012--up from 78% five years ago. Of the more than 1,000 people who completed the survey, 73% said that they had successfully hired a candidate through social networks.

Although LinkedIn still leads social media sites in recruiting use--attracting just about all recruiters using social tools--Facebook and Twitter both saw surges in 2012. Two-thirds of the surveyed group said that they use Facebook for recruiting, up from just over half last year. Similarly, Twitter has become a recruiting tool for 54% of respondents.

Dan Finnigan, CEO of Jobvite, says that while he doesn't foresee LinkedIn losing its lead, Facebook and Twitter will likely continue to grow steadily more important.

"Facebook engagement continues to grow every day, and as the generation of Facebook users is getting more senior in the workplace, they're more comfortable using Facebook to help them," Finnigan says. "And I think that [Twitter is] one of the most effective ways for a company to build awareness over time."

Since implementing social recruiting, 49% of respondents said that they saw an increase in quantity of candidates, and 43% said that they saw an increase in the quality.
