什么是错误链接？

根本不存在的链接，就是错误链接。

错误链接与死链接的区别：

错误链接是由于用户的疏忽，请求的链接不存在。

死链接是原来访问正常，后来因为网站的变故而不能访问。

发生错误链接的情况：

用户对域名拼写错误。

URL地址书写错误。

URL后缀多余了或缺少了斜杆。

URL地址中出现的字母大小写不完全匹配。

再谈Canonical标签

Canonical标签是用于指定网页主要内容的URL地址。它是一种标记语言标签，通过这个标签，可以告诉搜索引擎要把多个类似内容的页面合并成一个主要内容相同的页面，减少搜索引擎对同一内容的多个页面进行索引，避免重复内容的出现。通过设置Canonical标签，可以提高网站的SEO效果，降低网站被搜索引擎降权的风险。同时，Canonical标签也有利于网站内部链接的优化，提高网页被搜索引擎收录的几率。

Nofollow的具体使用方法

nofollow标签通常有两种使用方法：1、将"nofollow"写在网页上的meta标签上，用来告诉搜索引擎不要抓取网页上的所有外部和包括内部链接。<meta name="robots"content="nofollow" />2、将"nofollow"放在超链接中，告诉搜索引擎不要抓取特定的链接。<
