404错误链接对谷歌SEO的影响及排查方法
什么是外贸独立站的404页面？
What is a 404 Page for Foreign Trade Independent Websites?
404页面是用户在浏览网页时，服务器无法正常提供信息所返回的错误页面。当网站访客经常遇到打不开的页面时，他们可能会离开网站，而Google搜索引擎会因此降低你的网站排名。
A 404 page is an error page returned when the server cannot provide the requested information. If visitors frequently encounter inaccessible pages, they may leave your site, and Google may lower your website's ranking as a result.
