关于百度快照,官方给出的说明

一直以来,部分站长对百度快照的更新时间都存在一些误解,认为网站的快照更新时间与网站的权重状态存在一定关系,快照更新越频繁,网站的权重越高,反之,越低。

而实际上,网站快照的更新频率与权重并不存在任何直接的关系。

百度快照为什么会更新?

首先,需要澄清一下网页的抓取频率和快照的更新频率是完全不同的两个概念。

每一个被百度收录的网站,baiduspider都会根据其网站内容更新的频率不断的检查有无新网页产生,通常情况下,Baiduspider的抓取频率会和网站产生新内容的速度相符,通常说的更新,是指Baiduspider对网页内容的抓取。

每 个新抓取或者新检查过的网页,我们都会根据其重要程度以及其时效性价值以不同的速度去创建索引,通常所说的快照更新时间是指索引时间,一些经常有重要内容 更新的网页,我们会以更快的速度创建索引。如果一个网页只是一般的文字变更或者内容没有时效性的价值,并不一定会被搜索引擎认为有快速更新索引的价值,即 便百度蜘蛛重新抓取了该网页内容,其快照也不一定会快速更新,但这并不意味着它不重要或者百度更新的速度很慢。

快照时间为什么会倒退?

一 个重要网页的快照往往会在搜索引擎数据库中保存有多份网页快照,这些快照的抓取时间并不相同。在一些极特殊情况下,搜索引擎系统可能会选择不同于当前搜索 结果中的快照版本,导致出现快照时间倒退的情况。这对网站在搜索引擎中的表现无任何影响,也并不代表搜索引擎对该网站做了降权处理。

综上,快照的更新与页面中是否出现重要新增内容有直接关联,而与网站本身的“权重”、是否“被K”并无直接关联。站长不必过多关注网站的快照时间,我们建议站长将精力集中在网站的内容建设中,只有提高网站的内容价值和检索体验,方可受到用户和搜索引擎的信赖。
