内容比较多,大概意思:
1,Link evaluation. 链接评估
We often use characteristics of links to help us figure out the topic of a linked page. We have changed the way in which we evaluate links; in particular, we are turning off a method of link analysis that we used for several years. We often rearchitect or turn off parts of our scoring in order to keep our system maintainable, clean and understandable.
为了确定一个页面的主题,我们经常分析这个页面的众多外链。现在我们已经改变了这种链接评估方式。特别的一点是,我们还放弃了一种我们用了很多年的链接分析方式。具体放弃的是什么分析方式,大家都还在猜测,google官方也没给出。可能是锚文本。。。。。
