301永久重定向的设置方法大全

作者:admin日期:2017-07-23阅读

301重定向来实现权重的集中,因为在搜索引擎看来,带www和不带www的URL是2个完全不同的URL,当它们指向同一个网站时,会让搜索引擎不懂应该选择哪一个URL作为主要的域名。如果你用301重定向把其他几个URL如xiuzhanwang.com转到www.xiuzhanwang.com时,相应的PR也就集中在主域名:www.xiuzhanwang.com上了。

手机购彩注册 毫无疑问地,唯一的域名能够给你带来更多的好处。不管它是带www还是不带www。因为这样无论用户还是搜索引擎都会记住你网站的唯一域名。也不会造成权重的分流。
