Chinese search giant, Baidu, reported a 34 per cent jump in profit for the second quarter, with mobile ad sales accounting for almost a third of revenue for the first time.
Baidu's profit reached 3.5 billion yuan ($US571 million) for the quarter, while revenue soared 59 per cent to 12 billion yuan, at the upper end of its forecast.
Mobile made up 30 per cent of revenue, which was a first for the company, CEO Robin Li said in a statement. A day earlier, Facebook said it more than doubled its profit in the second quarter, with mobile a big factor.
Most of Baidu's revenue comes from online ads, and it's trying to squeeze more from mobile as more Chinese turn to smartphones to get online.
Baidu says it's China's top provider for mobile search, mobile mapping and app distribution. But it faces increased competition from local rivals like Alibaba Group and Qihoo 360, whose search products are growing in popularity.
Since last year, Baidu has spent a lot more on research and development and on marketing. In the quarter just ended, R&D expenses increased 85 per cent year over year, while general and administrative expenses doubled. Most of that G&A increase was for promoting mobile products, it said.
In the current quarter, Baidu expects revenue to reach as high as 13.8 billion yuan, an increase of 55 per cent from last year.
