Google Toolbar PageRank Update? Probably a Fluke
Google工具条的PR更新了?那很有可能是侥幸哦
I cannot tell you how many times we see threads that are either reporting or questioning if there is a Google PageRank update. We try to document all "real" toolbar PageRank updates here, but often, very often, there are smaller updates or not updates at all, of the PageRank bar, reported in the forums.
我不能告诉你我有多少次看见有关Google PR升级报道和疑问的线索。我们试图去报到所有“真实”的Google工具条PR升级事件，但是有是，也是经常发生，在论坛里报道PR工具条只有有一些比较小的升级或者一点都不升级。
I figured I highlight one such thread, because Google's JohnMu adds some insight into why people might see a PageRank 0 or update before its time.
我标出一条线索，就是在Google的JohnMu对“为什么人们可能会看见PR0或者升级”多了些关注之前。
A Google Groups thread has one member worried that his PageRank dropped from a 4 to a 0. John, from Google came in to ease this webmaster's concern.He said:
Keeping in mind that we only update PageRank for the Toolbar a few times a year, it might be that there was just some "fluke" with regards to your site right when we updated it. For example, it could be that at that moment, the www- or non-www version was more relevant, now that other version is. At any rate, I don't think you need to worry too much about that :). Two things that you could do are setting a preferred domain name in Webmaster Tools if you haven't done so already and setting up a canonical redirect to that preferred version.
一条Google官方blog的线索，关于一个成员对他的PR从4降到0的担忧，来自Google的John出来平息这位站长的担忧，他指出：
记忆当中我们一年只对Google工具条更新几次PR，就在更新的时候可能“侥幸”访问了你的站点。比方说，这可能在某些时候，www或者没有www的域名样式将更加关键，现在有一种其他的样式也是，至少我不觉得你应该对此过分担忧：)。有两点你可以做，那就是在站长工具中设置一个首选域名，如果你没做，那么去把规范的首选样式设置好。
In summary:
总结下来：
Toolbar PageRank is updated every few months
Google工具条中的PR只是几个月更新一次。
Other updates are likely flukes due to canonical issues or issues contacting Google's servers.
其他的更新更像是侥幸的常规事件或者说是Google服务器进场放生的事。
ehane点评：这篇主要就是说google工具条里面那个PR更新不要太在意，可能是侥幸事件，google一年更新不了几次，可能更新的时候正好抓到你的站了，要注意的事情就一个去Google的站长工具里，把首选域名设定下，要不是www的要不是没有www的，这样PR更新的时候，看到的更新值会比较真实。
