Chinese Internet search engine Baidu.com (BIDU) says its total revenues doubled for the second quarter ended June 30, 2007.

    "During the second quarter, we saw robust revenue growth and a healthy increase in online marketing customers," said Robin Li, Baidu's chairman and CEO. "These results reflect the successful implementation of strategic improvements made over the last two quarters and a growing recognition by Chinese businesses that Baidu's online marketing platform is a highly effective way to reach consumers."

    Total revenues in the second quarter of 2007 increased to RMB401.3 million, representing a 109.4% increase from the corresponding period in 2006. Net income in the second quarter of 2007 increased to RMB141.9 million, representing a 142.7% increase from the corresponding period in 2006.

    Traffic acquisition costs as a component of cost of revenues was RMB44.9 million, representing 11.2% of total revenues, compared to 9.2% in the corresponding period in 2006. The increase in TAC as a percentage of total revenues primarily reflects the continued growth of revenue contribution from Baidu Union members.
