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。

元标签代码该如何排序及该如何优化

排序： - charset（字符编码）应该放在最开始的位置，确保浏览器能正确解析页面的字符编码。 - viewport（视口大小）应该放在 charset 之后，这样浏览器能正确地渲染页面。 - keywords 和 description 可以放在 viewport 之后，因为它们为搜索引擎提供了关于网页内容的重要信息。 - 其余元标签可以放在最后，按照其在网页设计中的重要性排序。优化：

这么多死链类型，那我设置何种死链形态是最好的呢？

答：请站长注意，如果站点需要设置死链，请优先设置死链为协议死链404的状态！我们不建议用户将页面设置为http状态为200的内容死链，也不建议站长设置死链为跳转到首页的跳转死链形式！

死链是指在网站上出现的失效链接或链接到不存在的页面的链接。以下是处理死链的方法： 1. 删除死链：对于已经不存在或失效的链接，可以直接删除或替换为有效的链接。 2. 修复死链：对于原本是有效链接但因为某些原因变成死链接的情况，可以尝试修复链接，使其恢复有效。 3. 重定向：对于某些页面更改了链接地址，可以使用重定向方式让之前的链接跳转到新地址。 4. 自定义404页面：当访客点击某个不存在
