什么是死链

几乎所有的智能小程序或站点都会遇到内容失效、过期，页面不需要再展现的情况，这些无法对用户提供任何有价值信息的页面就是死链接，它包括协议死链和内容死链两种形式。

为什么要及时处理死链

当站点/小程序死链数据累积过多并且被展示到搜索结果页时，会影响百度搜索对站点/小程序的评价，对站点/小程序的访问体验和用户转化都会起到负面影响。另一方面，百度检查死链的流程也会为站点/小程序带来额外负担，影响对其他正常页面的抓取和索引。

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，
