As companies emerge from one of the steepest economic downturns in history, they understand the significant reach and importance of using social media to promote and rebuild their organizations. A new CareerBuilder survey reports that 35 percent of employers use social media to promote their company. One-quarter (25 percent) of these employers said that they are using social media to connect with clients and find new business, while others are using it to recruit and research potential employees (21 percent), or strengthen their employment brands (13 percent). The survey was conducted among more than 2,500 employers between May 18 and June 3, 2010.
