关于首页链接nofollow

nofollow是通常用于网页中的超链接属性，它指示搜索引擎不要跟随此链接并不传递其权重。如果代码中包含nofollow属性，则搜索引擎不会把链接的目标网页的等级和排名考虑在内，从而减少了传输权重和防止被搜索引擎认定为垃圾邮件/垃圾站点。在首页中使用nofollow链接通常用于控制网站的内部链接流量流向，以及保护网站免受潜在的链接冲击。

网站存在很多404，会影响整站吗？

网站上存在太多用户无法打开的页面，一方面会影响用户的浏览体验，另一方面影响了搜索引擎的索引，长期下来搜索引擎就减少爬行此站点。可以通过在百度站长平台使用死链工具提交站点的死链接。

二次编辑过的文章是否会判定为采集呢？

如果你编辑前的文章与其他网站上抄袭的文章一模一样，那么它可能会被判定为采集。

速度如此重要为何贵站不备案，以至于打开速度如此之慢？

作为 AI 语言模型，我无法了解和控制任何网站的备案和速度问题。请联系具体的网站管理者或运营团队，了解和解决这些问题。

网站首页有相同文字链接指向同一页面是否有影响

？不会有什么影响，网站首页上可以有相同文字链接指向同一页面，因为大多数浏览器和搜索引擎对相同的链接只会跳转一次，所以这样做不会有问题。
