404页面有什么用?
What's the use of the 404 page?
1、避免出现死链
1, avoid a dead chain
404页面会让网站无法打开的页面呈现404错误状态给蜘蛛,搜索引擎蜘蛛爬行这类网址得到“404”状态回应时,即知道该URL已经失效,便不再索引该网页,并向数据中心反馈将该URL表示的网页从索引数据库中删除。避免因为死链接影响网站收录。
The 404 page will let the web site cannot open the page to present the 404 error status to the spider, the search engine spider crawling this type of Web site to get "404" response, that is, know that the URL has failed, no longer index the web page, and to the data center to feedback the URL expressed in the web page from the database deleted. Avoid the impact of dead links on the site.
2、提升用户体验
2, improve the user experience
404页面比正常死链接视觉美观,同时也可以引导用户返回上一级或是首页,即留存了用户,也提升了用户体验。
The 404 page is visually beautiful than normal dead links, and it can also guide users to return to the upper level or home page, that is, to retain users and enhance user experience.
3、避免信任度下降
3, avoid the decline of trust
http状态码是蜘蛛和网页之间沟通的语言。当搜索引擎获得了一个错误链接时,网站应该返回404状态码,告诉搜索引擎放弃对该链接的索引。而如果返回200或302状态码,搜索引擎就会为该链接建立索引,这导致大量不同的链接指向了相同的网页内容。
HTTP status code is the language of communication between spiders and web pages. When the search engine gets a wrong link, the website should return the 404 status code and tell the search engine to give up the index of the link. If you return the 200 or 302 status code, the search engine will index the link, which leads to a large number of different links pointing to the same web content.
4、避免被惩罚
4, avoid being punished
和第3点相关,搜索引擎信任度下降。久而久之,网站面临着降权风险。
In relation to third points, the trust of the search engine is declining. For a long time, the website is facing the risk of reducing power.
