什么是重定向？

--------------------------------------------------------------------------------

A redirect is a way to send both users and search engines to a different URL than the one they originally requested.重定向是一种方式发送用户和搜索引擎不同的网址比他们原先要求。 Below are descriptions of some of the commonly used types of redirects.以下是对常用的重定向一些类型的描述。

301 Moved Permanently 301永久移动
A 301 Redirect is a permanent redirect which passes between 90-99% of link juice (ranking power) to the redirected page. 301重定向是永久性重定向的链接汁90-99之间（排名功率）％传递到重定向页面。 301 refers to the HTTP status code for this type of redirect. 301指的是HTTP状态码此类型的重定向。 In most instances, the 301 redirect is the best method for implementing redirects on a website.在大多数情况下，301重定向是实施最好的方法在网站重定向。

302 Found (HTTP 1.1) / Moved Temporarily (HTTP 1.0) 302（HTTP 1.1中）/移动暂时（HTTP的1.0）
A 302 Redirect is a temporary redirect and passes 0% of link juice (ranking power) and in most cases should not be used. 302重定向是一个临时重定向的链接，并传递零果汁（排名功率）％，在多数情况下不应该使用。 The Internet runs on a protocol called HyperText Transfer Protocol (HTTP) which dictates how URLs work.互联网上运行的协议称为超文本传输协议（HTTP）的网址，这就决定如何工作。 It has two major versions, 1.0 and 1.1.它有两个主要版本，1.0和1.1。 In the first version 302 referred to the status code 'Moved Temporarily'.在第一个版本提到了302状态码'移动暂时'。 This was changed in version 1.1 to mean 'Found'.这是改变了1.1版意味着'发现'。

307 Moved Temporarily (HTTP 1.1 Only) 307移动暂时（HTTP 1.1的只）
A 307 Redirect is the HTTP 1.1 successor of the 302 redirect.一个307重定向是HTTP 1.1的302重定向的继任者。 While the major crawlers will treat it like a 302 in some cases, it is best to use a 301 for almost all cases.而主要的抓取工具会像对待一个302它在某些情况下，最好使用几乎所有情况下301。 The exception to this is when content is really moved only temporarily (such as during maintenance) AND the server has already been identified by the search engines as 1.1 compatible.唯一的例外是当内容是真的很感动（在维修过程中如）只是暂时的，该服务器已被作为兼容1.1的搜索引擎识别。 Since determining if the search engines have identified this essentially impossible, it is best to use a 302 redirect.由于搜索引擎确定是否已确定这基本上是不可能的，最好是使用302重定向。

Meta Refresh元刷新
Meta refreshes are a type of redirect that is executed on the page level rather than the server level (They are usually slower and not a recommended SEO technique).元刷新是一种类型的重定向页面级别上执行超过了服务器级（它们通常速度较慢，不推荐搜索引擎优化技术），而。 They are most commonly associated with a 5 second count down with text "If you are not redirected in 5 seconds, click here".他们是最常见的与一个5秒的倒计时与文字：“如果你没有在5秒内重新导向，请点击这里。” Meta refreshes do pass some link juice but are not recommended as an SEO tactic due to usability and the loss of link juice passed.元刷新通过一些链接果汁，但不是作为一个SEO策略，由于实用性和建议通过链接汁损失。
