谷歌PR值普遍大跌 激怒博客和门户网

　　【计世网讯】(伯牙 编译)10月29日消息，据国外媒体报道，谷歌PageRank(PR)值近日出现了大地震，很多网站的PR值从7骤降至5。

　　PR分数决定着一个网页在搜索排名中的位置，分数越高，排名就越靠前。但近日，大量知名门户网站和博客网站的PR值从7骤降至5，引发了人们的不满。

　　例如，福布斯(Forbes.com)、华盛顿邮报(WashintonPost.com)、SFGate.com、SunTimes.com和Engadget.com等网站均从PR7降至PR5。

　　对此，有业内人士认为，可能是因为谷歌调整了PageRank算法所致。但是，谷歌却给予了否认，称并未调整PageRank算法。
