404页面该怎么做？

404页面是指在网站中访问的页面不存在或者找不到时，服务器返回的错误页面，一般返回状态码为404。以下是404页面的制作建议： 1. 突出提示信息：应突出404错误提示信息，告知用户页面不存在，并给予建议或转到网站首页。 2. 留下联系方式：如果是用户信息输入错误导致的404页面，可以留下联系方式，方便用户与网站联系。 3. 美化页面设计：可以设计一张有趣、富有创意或者符合主题的图片作为404页面，以吸引用户的注意力。 4. 提供搜索框：在页面中添加一个搜索框，允许用户输入关键字搜索相关信息。 5. 避免404的避免：通过网站地图和语义化URL等策略可以降低404页面的出现率。总之，一个好的404页面能够使用户对网站的印象更加深刻，也能提升网站的用户体验和用户留存率。

浅谈404问题

今天为什么要说一下404问题呢,最近看case过程中发现个很有意思的网站，该网站被灌了大量的垃圾信息，被其发现后及时地进行了删除，这一点是值得肯定的。通常情况下，正常网站将自动返回404状态码，搜索引擎进行更新并删除，避免对网站用户及搜索引擎带来负面影响。但问题来了，该网站只删除了内容，没有任何主体内容的页面被保存了下来，未做404处理。当然，存在一类网站只删除内容后返回正常200状态码，提醒一句
