对于设置301重定向有很多好处,其中之一就是利于seo防止搜索引擎误操作将多域名站点设置为作弊站点,同时也减少权重分散,像访问www.ihuan.me/1046.html则会被跳转到ihuan.me/1046.html增强流量的汇集。具体方法如下。

1.新建一个站点,对应目录如D:\wwwroot\301web。该目录下只需要1个文件,即index.html或者加个404.htm。绑定要跳转的域名,如图:
2.在IIS中选中刚才我们建立的站点,右键,属性,主目录,选择重定向到,输入网址如:http://www.xxxx.com,同时注意选中下面的资源的永久重定向选项。如下图:
3.到此,我们已经完成了将xxxx.com这个域名301重定向到www.xxxx.com的工作。
注意问题:
“上面输入准确的 URL(X)”这个选项建议不要选。
不选的结果是:
当输入xxxx.com转到了www.xxxx.com,
当输入xxxx.com/sanwen/suibi/时,转到了www.xxxx.com/sanwen/suibi/。
选上的结果是:
当你输入xxxx.com或者xxxx.com/sanwen/suibi/都会转到www.xxxx.com。
好了,如果只是想把不带www的转到带www的或者其他没有用过的域名转到正在使用的域名,这样就可以了。但是如果你要的域名已经做过网站,想要把权重传递给新网站,可以参考下面这个方法:
第一步同上,主要是第二步,如图:
注意红色字体的部分,在重定向到地址的后面多了$S$Q字符,即写成了http://www.xxxx.com$S$Q。“上面输入准确的 URL(X)”这个选项也打了勾。
对于$S$Q字符,这里解释一下:
$S 将请求的URL 的后缀传递给新的URL。后缀是用重定向的URL 代替之后,初始URL 中所保留的部分。
如果未设置 EXACT_DESTINATION 标志,则结果目标URL 的名称将具有所请求文件的名称(作为文件夹名称)以及文件名本身。
$Q 将初始URL 中的参数(如 querystring 参数)传递至新的 URL,包括问号(?)。
如果不加上$S$Q字符的话,内页的301都会跳转到首页,加上$S$Q字符的目的就是内页也能准确的跳转到新域名的对应内页。
好了,这样就完成了301永久重定向的设置,设置好之后最好能测试下是否返回的是301值,推荐个网址:http://www.seoconsultants.com/tools/headers。
百度对301的反应并不像想象中那么慢,第二天就收录了xxxx.com这个页面,快照最新。当然,快照的内容是www.xxxx.com的内容,而不是301web里index.html的内容。
