叨叨死链这回事儿

叨叨死链（Toast Dead Link）是一种网页中常见的死链接，常常会发送访客一个404错误页面，表明页面找不到了。它们通常是来源于旧网站上错误的链接，或是网站本身不小心也犯了错误，把问题给留下来。叨叨死链不仅造成了一些糟糕的用户体验，还可能会影响SEO，引起搜索引擎抓取信息失效，影响网站的整体排名。

sitemap提交后，还需要大量的人力进行维护吗？

不需要，您可以根据具体情况进行定期维护。

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。

死链出现的三种情况

网站改版或者网站搬家后，文件移动了位置，导致指向链接变成死链接；曾经存在的页面被删除，对应的链接就是死链接；文件夹名称修改，导致路径错误编程死链；网站还没做好就急于上线，导致大量死链

死链包括协议死链和内容死链两种形式

协议死链：指页面的TCP协议或者HTTP协议状态明确表示的死链，我们常见的404、403、503就属于协议死链；内容死链：指服务器返回状态是正常的，但是网页内容已经变更为不存在、已删除或需要权限等与网站原内容无关的信息页面。
