July 30 (Reuters) - LinkedIn Corp, operator of the biggest social networking site for professionals, reported a bigger quarterly loss as costs rose and a strong dollar eroded the value of income from outside the United States.
The company said its net loss attributable to shareholders widened to $67.7 million, or 53 cents per share, in the second quarter ended June 30, from $1 million, or 1 cent per share, a year earlier.
Revenue rose 33.3 percent to $711.7 million.
LinkedIn has been spending heavily to acquire businesses and build up its sales and development teams in an effort to leverage off LinkedIn.com's about 380 million members. (Reporting by Devika Krishna Kumar in Bengaluru; Editing by Ted Kerr)
