根据预测,2009年google pr值的第一次更新应该会在10天内的3月27日,10天后再查看是否更新。有人说是2009年第一次更新发生在单独下降google日本的惩罚上。还有人说google已经开始提前清算部分违规网站。以下是转载的2000年以来google pr值的历次更新:
*其中tbpr export指google工具条接口数据更新,gdpr export指google directory接口数据更新,bl export指反向链接数据更新。
*google pagerank 是 google 衡量网页重要性的一个指标,其值从0到10共分为11个等级,其数值越大,说明这个网页也就越重要。当然,想要升的越高,其难度也就越大,由于 pr值算法保密,我们无从知晓影响pr值的具体算法;但是许多网友根据各种迹象,推测出了一些关于 google pagerank 的秘密。
