Q：网站加入过多的Nofollow 标签，会不会有影响？

加入过多的Nofollow标签可能会对网站的SEO影响。Nofollow标签是一种HTML标签，用于告诉搜索引擎不要追踪或传递链接的权重。当网站过多地使用Nofollow标签时，可能导致以下问题： 1. 爬虫无法发现和索引页面：搜索引擎通过爬虫来发现和索引网页，但如果过多的页面使用了Nofollow标签，搜索引擎可能无法追踪这些页面，导致这些页面无法被索引到。 2. 链接权重流失：Nofollow标签可以阻止搜索引擎传递链接权重，过多地使用这个标签可能会导致网站内部链接的权重无法传递到其他页面，影响网站的整体权重分配。 3. 网页排名下降：搜索引擎通常将链接视为网页排名的一个重要因素。如果网站过多地使用了Nofollow标签，可能导致少量链接被传递链接权重，从而影响网页在搜索结果中的排名。因此，为了最大程度地利用链接权重和提高网站的可见性，建议谨慎使用Nofollow标签，尤其是在内部链接中。确保将Nofollow标签合理地应用在外部链接上，以避免对网站的SEO产生负面影响。

网站被克隆复制后关键词排名一直往下掉

邹生提问于 3年之前网站内容被恶意克隆，对方域名年龄比我久，在发现克隆我网站域名收录后的隔天就发现排名开始下滑，去百度投诉对方侵权也没用。不知道zac大大对于被克隆后网站排名下降有什么好的解决方法吗2 个回答Zac 管理员回答于 3年之前从技术上，别人克隆或复制或采集你的网站，是没有解决办法的。只要你不关闭网站，或者把内容藏在登录页面后面，就没办法阻止别人访问你的网站，也就没
