谷歌PR值普遍大跌 激怒博客和门户网

  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。

  以下为受此次“地震”影响的部分网站名单:

  知名博客网站:

  Engadget (from 7 to 5)
