Increased recruitment activity at Dice.com and eFinancialCareers.com led to a 33 percent increase in net income during the second quarter for Dice Holdings Inc., the company reported.

Along with its earnings, the company also announced the launch of a new product, the Dice Talent Network.

Dice Holdings said it earned $3.7 million on revenue of $29.9 million during the quarter, compared with net income of $2.8 million on revenue of $27 million during the second quarter of 2009.

For the first six months of 2010, Dice Holdings earned nearly $7 million, up 5 percent from the first half of last year.

In addition to Dice.com, a recruitment website for technology employers and job-seekers, and eFinancialCareers, a recruitment site for financial careers, Dice Holdings operates ClearanceJobs.com, AllHealthcareJobs.com, WorldWideWorker.com and Dice Career Fairs.

The Dice Talent Network enables companies to build a network of career-minded technology professionals with interest in their companies. Employers can communicate directly via real-time chat or instant message as well as release network-wide announcements about new positions or opportunities. With an enhanced profile, the employer can offer — at their discretion — a more personal and introspective look at the company and its culture to technology professionals.
