谷歌网页排名之谜 [英] Google Page Rank mystery

问题描述

我有一个业余爱好网站：

http：// www.montana-riverboats.com

也解析为：
http://montana-riverboats.com ...没有www。


一个地址的Google页面排名为3。

另一个地址的Google页面排名为4。

（至少根据Firefox页面排名插件）。


怎么能这样是？他们是同一个网站。

谷歌是否计算两个（在域名中有和没有www）

作为单独的网站？这是否意味着所有外部链接

指向www版本不计算非www版本？

什么时候应该？

我认为谷歌很聪明。他们怎么这么透明呢？b $ b傻了，而不是解决它？如果他们将域名存储在

a B-Tree之类的结构中，那么确定重复地址并获得正确就很容易，而且并不是那么昂贵。 />

事实上，围绕重复的b / b $ b $和破碎的网站信息的运行时费用，你会认为比存储更贵b / b
一次......正确的方式。

I have a hobby website at:

http://www.montana-riverboats.com
which also resolves as:
http://montana-riverboats.com ...without the www.

One address has a Google page rank of three.
The other address has a Google page rank of four.
(at least according to the Firefox page rank plugin).

How can this be? They are the same site.
Does Google count the two (with and without www in the domain name)
as separate sites? Does this mean all the external links
pointing to the www version don'' count for the non-www version?
When they should?
I thought Google was smart. How can they be so transparently
stupid, and not fix it? If they store domain names in
a B-Tree like structure, it would be easy, and not all that
expensive, to determine duplicate addresses, and get right.

In fact, the runtime expense revolving around duplicated
and fractured site information would, you would think, be
more expensive than storing it once...the right way.

（有1个入站链接）

也可以解析为：
http://montana-riverboats.com ...没有www。


（约34个）

一个地址的Google页面排名为3。
另一个地址的Google页面排名为4 。


可能是因为一个人的入境链接多于另一个人

这怎么可能？他们是同一个网站。


如果他们是同一个网站，那你为什么要用两个不同的

网址发布它？

I have a hobby website at:

http://www.montana-riverboats.com
(which has 1 inbound link)
which also resolves as:
http://montana-riverboats.com ...without the www.
(which has about 34)
One address has a Google page rank of three.
The other address has a Google page rank of four.
Probably because one has more inbound links than the other
How can this be? They are the same site.
If they''re the same site, then why are you publishing it at two different
URLs?

如果这困扰你，那么停止在不同的地方发布相同的内容>
网址。


是什么让你认为这与HTML创作有关？

想一想！ *确切地说*谷歌应如何确定

< http://www.montana-riverboats.com>和< http://montana-riverboats.com>

实际上是同一个网站？由于www，前缀只是一个约定，

并不总是遵循，它*不能* - 因为它们*不是*

必然是同一个网站！即使两个网址都解析为同一组

IP地址，它们仍然可以是单独的网站（因为，在HTTP

v1.1下，主机标题在同一个

服务器上允许许多不同的虚拟站点。


如果你希望它们被视为同一个站点，*你*必须告诉

世界他们是一样的。我建议设置

< http://montana-riverboats.com/...>通过

永久移动来回复所有请求重定向状态为

< http://www.montana-riverboats.com/...>。 IIRC这很容易用Apache，

和其他网络服务器软件。不要*尝试使用

< META REFRESH ...>黑客 - 它不会做你需要的（以及

效率低下）。

Think about it! *Exactly* how is Google supposed to determine that
<http://www.montana-riverboats.com> and <http://montana-riverboats.com>
are in fact the same site? Since the "www" prefix is only a convention,
and not always followed, it *can''t* -- because they are *not*
necessarily the same site! Even if both URLs resolve to the same set of
IP addresses, they could still be separate sites (since, under HTTP
v1.1, the "host" header allows many different virtual sites on the same
server).

If you want them to be treated as the same site, *you* have to tell the
world that they''re the same. I''d suggest setting up
<http://montana-riverboats.com/...> to respond to all requests with a
"moved permanently" redirection status to
<http://www.montana-riverboats.com/...>. IIRC this is easy with Apache,
and probably with other web server software. Do *not* try to use the
<META REFRESH...> hack -- it won''t do what you need (as well as being
less efficient).

....我的共享主机ISP在他们的http.conf中做了这个，不管我喜欢它

或

不行。这很常见。许多ISP都这样做。所以隐含的www映射

是在网络上发生数百万次的事情。

两个Urls都解析为相同的IP地址。对于

谷歌来说，这并不难。

是什么让你觉得这与HTML创作有什么关系？

If they''re the same site, then why are you publishing it at two different
URLs? ....my shared host ISP does this in their http.conf, whether I like it
or
not. This is common. Many ISPs do that. So the implied "www" mapping
is something that happens millions of times, all over the net.
Both Urls resolve to the same IP address. It wouldn''t be hard for
Google to figure that out.
What makes you think this has anything to do with HTML authoring?

....我可以假设我可以发布到''服务器''组。

然而，有人肯定抱怨''谷歌''

问题与服务器无关。一本书的作者

需要知道如何写作，以及如何与出版商打交道以及

营销。

....I could suppose I could have posted to a ''servers'' group.
Someone there, however, would surely have complained that ''Google''
questions have nothing to do with servers. The author of a book
needs to know how to write, plus how to deal with publishers and
marketing.
