网站Google排名从首页往下掉的原因分析

Reasons for being kicked from the top 10. 最近Google再进行着一次例行,却又不同寻常的更新Jagger1,2,3. 不少长期关键定排名在Google长期稳定的网站,排名也往下掉,甚至于排到几十名之外,是什么原因导致网站排名在本次更新中剧烈下滑的呢?PS: 这篇东西从WMW论坛上看到,觉着不错,逐就试试翻译过来,希望能给大家一些提示。

1) Dupe content (this includes others stealing whats yours and putting it on their site)

中文:1, 重复文件,包括别人偷取你的网页内容,放置在他们自己的网站上;
[PS:当自己站内有大量的重复页面时(页面相似度太高),也会产生Dupe Content]

2) www and non www (same as above check if there is an index / caching of http://www.mysite.com and http://mysite.com

中文:2, "www" 和 "non www" 就是同时存在"http://www.mysite.com"和"http://mysite.com"不同的索引问题,可以在Google里查询索引或缓存发现;

3) Site wide links from others (check your backlink on all search engines if there is a site pointing to you from lots of its pages it can be construed as "bought links")

中文:3,从某一站点来的过量外链,在各个搜索引擎里检查你的反链,看看是不是有站点给你过多的反链,由此你被怀疑为“收买”链接;

4) Link pages (if you have pages of outward links make sure they have content not just links)
中文:4,站内建有“友情链接”页,没有内容,只包含大量的外出链接。如果你有这样的网页,请不要让此页的内容太单薄;

5) Unnatural growth (if you are working on content and adding more than 1 page a day google thinks this is unnatural and can kick you for it .. really stupid reason imo but there we are)

中文:5,网站(内容)成长速度不正常,网页按每天多于一页的数量增加,过多的增加内容,这可被Google认为不正常,听起来有点奇怪;

6) Site wide change of page structure (if you suddenly change your template site-wide this can kill your site .. i guess this is really a case of design it correctly in the first place)

中文:6,网站内部结构突然改变,如果你突然在全站范围内改变你的网页模板,这可能会把你的站往悬崖下推,因此网站内结构的变更,其是否会带来网站排名的变化,是一个很值得考虑的问题;

7) Server problems (googlebot having trouble usually only happens if you have changed servers recently)

中文:7,网站服务器的问题(近一段时间来,只有你换虚拟主机空间商,或者改服务器的IP地址,这样GoogleBot会碰到问题,当然服务器宕机更成问题)
