网站做301重定向（www.xxx.com跳转到xxx.com）有必要吗？

1 个回答

Zac 管理员回答于 3年之前

有必要。

不知道做SEO的是不是都清楚，xxx.com是域名，www.xxx.com其实是xxx.com的子域名，这两个并不是平级的，只不过当初设计网站相关协议时，world wide web是对网站这个东西的最常用称呼，缩写为www，所以大家习惯访问网站时用www.xxx.com这个地址，一看就知道是world wide web嘛。

但www.xxx.com和xxx.com是两个不同的URL地址，其显示的内容可以一样，通常也都一样，但技术上完全可以显示不一样的内容，就像正常子域名一样。所以，搜索引擎也并不天然把这两个URL当作是一回事，虽然大部分情况下搜索引擎知道这两个URL应该是一回事。

作为站长，应该向搜索引擎表明和确认，这两个URL是一回事，方法就是其中一个做301跳转到另一个，301指向的那个是规范化的网站首页，搜索引擎在搜索结果中应该显示规范化的那个URL，权重也应该集中到规范化的URL。

不做301转向会怎么样呢？如果搜索引擎判断正确，这两个是一回事，那也不会怎么样。但如果搜索引擎判断错，或不能下结论呢？那可能就会把权重分散在两套URL上。作为SEO，其实很多工作都是在帮助搜索引擎正确判断，而不是让搜索引擎自己看着办。

网站每天采集内容会降权吗

威海seo问答威海网站降权

问题：我的网站没有原创，用火车头采集会降权吗？回答：搜索引擎不要求网站一定做原创，只要求提供优质内容，所以不做原创不会降权！但是如果只是‘纯粹的克隆’形式的采集站，那么就没有生存的必要了。要知道：内容的选择性，很重要！这篇内容是不是有转载的必要？为什么要做采集。你把多个网站的优质内容聚合下，一样可以。来源：A5营销

内页收录正常就是没有排名

，如果出现排名，则可能存在因素可能是： 1、网站内容质量、权重：网站内页的质量越高、权重越大，收录的机会就越大，有利于网站排名。 2、网站Url地址：站内页的地址重要性也至关重要，搜索引擎越容易把握站内页的实体意义和URL地址之间的联系，网站越容易被搜索引擎收录，从而有利于网站排名。 3、网站标题与内容：网站标题能够准确描述网站内容，并且与内容能够相互补充，有利于搜索引擎对网站进行页面

yos 提问于 3年之前我的URL中有两个数字参数，一个是类别id, 一个是文章ID, 不知道该用下划线还是斜杠分隔好。如下：一、seozac.com/1_1.html二、seozac.com/1/1.html目前采用的形式是一，排名也比较理想，但不知何故，最近突然发现百度收录的是 1_1.html，但从搜索结果里直接打开的网址却是 1.html （忽略了下划线以及前面的类别ID）如果采用第二种
