LinkedIn recently has been adding more features and redesigning its website in an effort to give people a reason to visit more frequently and stick around longer. The company also has been rolling out more applications for smartphones and tablet computers to make it easier for members to connect when they are away from the home or office. Those efforts could help LinkedIn sell more online advertising. The company currently gets about two-thirds of revenues from the various fees it charges to mine the profiles and other data on its website.WHY IT MATTERS: LinkedIn is playing an increasingly important role in the employment market as it changes the way that people find jobs and the way that employers fill them. WHAT'S EXPECTED: Analysts are forecasting earnings of 11 cents per share on revenue of $244.6 million, according to a poll by FactSet. The earnings projection doesn't include the company's expenses for employee stock compensation. LAST YEAR'S QUARTER: The company lost $1.6 million, or 2 cents per share, on revenue of $139 million. Profit would have been 6 cents per share if not for the costs of employee stock compensation and charges unrelated to its ongoing business.
