The trend of precise advertising targeting is gradually gaining momentum. Yesterday, Tencent (0700.HK) launched a precise targeting system for online advertising, marking the first time a Chinese internet portal company has independently introduced such a technology for targeted online advertising. "Different users visiting Tencent's website will see different ads," said Yuetping Jiang, General Manager of Tencent's Advertising Platform and Products Department, in an interview with The First Financial Daily. He added that this precise ad placement system will encompass platforms such as Tencent's portal site and its instant messaging tool QQ.
