搜索引擎自己应该是可以检测协议死链（404、403等）的，为什么还需要站长提交？

因为，搜索引擎对各类网页的抓取过程可能存在不可抗力的因素，比如网络延迟、缓存策略、主机垮掉等，可能会导致抓取异常，无法正常检测死链。这时就需要站长通过提交，及时通知搜索引擎，让其及时发现并修复死链。

301永久重定向作用

301永久重定向是一种HTTP状态码，使浏览器或搜索引擎知道该网页已永久移动到另一个网址。这种重定向通常用于网站重新设计、更改域名或更改URL结构的情况下。它会直接跳转到新的网址，而不是像302临时重定向那样保留原始URL。301永久重定向可以保持网站的搜索引擎排名和链接值，并帮助用户找到正确的网页，提高用户体验。
