SEO | 什么是负面SEO-站长须知

seo.jpg


    负面SEO指的是自己网站排名做不上去时,通过一些方法,通常是不正当的方法,把竞争对手的页面拉下来,有时候效果和自己页面排上去差不多。


    这里说的负面SEO和利用SEO手段压制公司负面新闻(或者叫搜索引擎上的网络负面危机公关和名誉管理)没什么关系。


     常见的负面SEO方法包括: 给竞争对手制造大量垃圾链接 意图使搜索引擎误判而惩罚目标网站。


    外部链接目前还是所有搜索引擎排名算法的重要部分,但所有搜索引擎都不喜欢不自然的链接,极力打击垃圾链接。


    Google的企鹅算法、百度的绿箩算法都是打击链接链接的。 典型的垃圾链接包括群发博客评论、论坛留言、链接农场、大量无意义的免费博客等,甚至新闻发布、模板版权链接、客座博客等看似不太垃圾的链接也经常被认为不自然。 


    既然垃圾链接可能导致网站被惩罚,就有人专门给竞争对手制造这些垃圾链接。搜索引擎能否正确判断垃圾链接是竞争对手制造的?大部分情况下没问题,有的时候会误判,不然也不会开发拒绝外链工具了。 




    制造大量重复内容 大量抄袭网站内容,甚至直接制造大量镜像网站,使搜索引擎认为目标网站存在大量复制内容。 一般来说,重复内容并不是一个被惩罚的理由,网站内部由于技术原因就可能出现重复内容,网站之外也会有正常的转载。但如果一个网站所有内容都在其它网站出现,这个网站的总体质量可能会被影响。 


    在百度或Google搜索一下“小寒云博客”,会看到几十个整站镜像我这个小博客的。


    当然,绝大部分不是为了负面SEO我,而是有人买个域名还没东西放,就先镜像个网站试着玩。 黑进竞争对手网站做手脚 有的手脚比较容易发现,比如挂个马,挂个黑链。


    被挂马的网站搜索结果中经常会被标注,访问时浏览器会提示有风险,百度站长平台和Google Search Console中也很可能会有通知。被挂普通黑链,经常看看网站就知道了。 


    隐蔽一点的,放些隐藏内容、隐藏黑链,得看源代码才能发现了。


    或者搜一下“site:domain+高利益关键词”,越是高风险高回报的词,越是有人越过底线当黑客,经常看看自己网站上是否有不该出现的色情、隐疾、私服、赌博等内容。 


    再隐蔽一点,做个cloaking,自己访问网站得到的内容和搜索引擎抓取的内容是不一样的,所以即使看源代码也不一定看到被黑了,比如前些天写的网站被黑怎么办的情况。


    这时需要查看快照,或者用站长工具中的抓取工具。 


    修改一下robots文件,禁止抓取页面,或者页面加个noindex标签之类的,也都可以使网站页面消失。 不要天真地认为这些倒霉事不会发生在你身上,上面这些情况我在客户网站上都见过。 


    攻击目标网站 如DDOS攻击,使搜索引擎认为网站不能访问了。


    短时间还好,超过一两天,搜索引擎为了自己用户的利益,很可能就不再显示这个网站页面了。


    一次攻击,通常过后搜索引擎排名能顺利回复,但三天两头不能访问就会成问题了。 


    制造大量 404 错误 制造大量链接到不存在的页面,因此产生大量 404 错误。和重复内容一样, 404 本身是经常出现的,页面被删除,别的站长链接时写错URL,都很正常,但数量大了也可能会对网站整体质量产生负面效果。


     垃圾转向 把大量垃圾域名、被惩罚过的域名做转向到目标网站。


    搜索引擎惩罚是可以传递的,一个域名被惩罚,不能简单地注册个新域名,内容不变,把老域名转向到新域名,老域名的惩罚可能会被传递到新域名,新域名就白费了,也不解决问题。


    要解决被严重惩罚问题,需要先找出导致惩罚的原因并解决掉,而不是单纯换个域名。 把被惩罚过的域名转向到竞争对手,也可能引起搜索引擎误判,把惩罚传递过去。当然另一方面,搜索引擎没有误判的话,弄不好把竞争对手域名做得更强了!
