死链是如何形成的

值得注意的是，死链接并不是错误链接，错误链接是由于用户输入网址错误而根本不存在的链接。死链接则并不出一出现就是“死”的，它是曾经正常的链接，由于某种原因导致现在失效的链接。

什么是死链

所谓死链指的是一种网络链接或链接到URL，但它不能正确载入页面或响应该URL，即无法找到对应的服务器。这指的是一个在网页上提供的服务或另一种连接，但它无法正确指向一个可用的 Web 服务器来载入所要求的文件。它可以是因为 URL 拼写错误、旧的 URL 地址以及域名过期或者文件已经被删除或移动等原因。

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。
