如何处理死链

404错误页面：很多站长会选择做一个404页面，来引导用户去其他页面。但是为死链制作404页面只是为了引导用户去其他内容页面，却没有真正解决死链的问题，因为搜索引擎爬虫并没有放弃抓取死链，依然存在着资源浪费和降权的危险。

提交死链：打开百度站长平台，左侧有一个死链提交通道。但千万要注意，robots.txt不要屏蔽这些死链，因为既然要提交给搜索引擎，那么爬虫就会去检查，如果被屏蔽了，爬虫会抓取不到，提交也就没有意义了。

屏蔽死链：可以将死链整理在文档中，然后将robots.txt上传到网站根目录即可实现对死链接的屏蔽。

站点名设置规范

1、信息来源的定义指一个网站/智能小程序的名字，起到区别不同网站/小程序的目的。在搜索结果页中，名称展现在左下角，更直观地体现了内容来源，加强了搜索用户对内容来源的信任度、对站点品牌的记忆度。2、站点名的设置原则：1）一致性：源码中的Tagtitle、Description中的站点名称应一致，且都与落地页内的实际的站点名一致。2）辨识性：站点名称应辨识性高，尽量体现站点的唯一性，避免较宽泛、无辨识

死链工具

死链指页面中超链接指向的目标网页不存在或已失效的链接，使用死链工具可以快速检测出这些无效链接并进行修复，避免影响页面的用户体验和搜索引擎排名。以下是几款常用的死链工具： 1. Xenu Link Sleuth：一款免费的原生桌面应用程序，支持 Windows 系统。可以快速检测出网站中的死链、重定向等问题，并提供详细的报告。 2. Dead Link Checker：一个在线死链检测工具，可以

什么是死链

我们在打开网址时，有时会出现“访问的页面不存在”的提示，这是死链的一种最直白的表现方式：通过某个链接进来后发现打不开或者是404页面，那么这个链接就叫做死链。
