What don't this still calculate, the mainest is:? of capture Yu alkyne returns? of serve of bursa post Xin a piece of pictures are contained so a keyword, so after you are searched, before a few when come out are him Baidu commonly, this statement that whole station makes is not exceptional also, even sina, these portals also kick Netease below go------I can say the Baidu 2008 is more overbearing only, I am Baidu who am I afraid of....

这还不算什么，最主要的是：哪怕百度产品的一个问题，一张图片带有那么一个要害词，那么你搜索以后，出来的前几位一般都是百度自己，整站做的这个词也不例外，甚至新浪，网易这些门户也踢到下面去------我只能说2008年的百度更加霸道，我是百度我怕谁。。。。
