Google 排名的200个影响因素: 网站级别因素
62. Content Provides Value and Unique Insights: Google has stated that they’re on the hunt for sites that don’t bring anything new or useful to the table, especially thin affiliate sites.
内容是否有价值，是否独到：Google在他们的帮助文档中明确表示他们会注意那些内容毫无价值毫无新意的网站，特别是代理站点。（也可以理解为站群，联署计划等）
63. Contact Us Page: The aforementioned Google Quality Document states that they prefer sites with an “appropriate amount of contact information”. Supposed bonus if your contact information matches your whois info.
联系我们页面：前面多次提到的页面质量评分手册里面说到Google比较偏爱那些提供了尽量多且准确的联系信息的网站。而且会与Whois的信息进行匹配。
64. Domain Trust/TrustRank: Site trust — measured by how many links away your site is from highly-trusted seed sites — is a massively important ranking factor. You can read more about TrustRank here.
域名信任度：域名的信任度主要靠高质量的信任外链来源，关于信任排名(Trust Rank)的更多信息可以参考这个页面。
65. Site Architecture: A well put-together site architecture (especially a silo structure) helps Google thematically organize your content.
站点结构：良好的站点结构可以帮助Google更好地理解并组织你的内容。
66. Site Updates: How often a site is updated — and especially when new content is added to the site — is a site-wide freshness factor.
站点更新频率：站点的更新频率，特别添加新内容的频率是整站的一个新鲜度指标。
67. Number of Pages: The number of pages a site has is a weak sign of authority. At the very least a large site helps distinguish it from thin affiliate sites.
页面数量：这个指标其实影响可以忽略不计，主要是帮助Google识别真正有质量的站点和劣质的代理网站。
68. Presence of Sitemap: A sitemap helps search engines index your pages easier and more thoroughly, improving visibility.
站点地图（Sitemap）：如果你的网站没有一个组织良好的站点地图，那快去补课吧，这个是基础中的基础。
69. Site Uptime: Lots of downtime from site maintenance or server issues may hurt your ranking (and can even result in deindexing if not corrected).
网站服务器是否稳定：一个经常宕机无法访问的网站Google肯定是不喜欢的。在2011年的时候我公司的网站由于服务器宕机20多个小时，恢复后流量直接少了三分之一。
70. Server Location: Server location may influence where your site ranks in different geographical regions. Especially important for geo-specific searches.
服务器位置：这个主要影响在特定搜索引擎中的排名，比如你的目标是google.fr，那么把服务器放到法国肯定会有加分。
71. SSL Certificate (Ecommerce Sites): Google has confirmed that they index SSL certificates. It stands to reason that they’ll preferentially rank ecommerce sites with SSL certificates.
SSL证书：这个仅仅针对电子商务网站，而且Google也明确表示他们会收录SSL证书。
72. Terms of Service and Privacy Pages: These two pages help tell Google that a site is a trustworthy member of the internet.
服务条款和隐私政策页面：这两个页面也是你的网站是否正规可信的参考依据。
73. Duplicate Meta Information On-Site: Duplicate meta information across your site may bring down all of your page’s visibility.
网站重复的Meta信息：重复的meta信息会显著降低你的页面的可见度。
74. Breadcrumb Navigation: This is a style of user-friendly site-architecture that helps users (and search engines) know where they are on a site:
Breadcrumb Navigation
Both SearchEngineJournal.com and Ethical SEO Consulting claim that this set-up may be a ranking factor.
面包屑导航：用户友好的网站结构必须要有面包屑。
75. Mobile Optimized: Google’s official stance on mobile is to create a responsive site. It’s likely that responsive sites get an edge in searches from a mobile device.
移动平台优化：未来是移动互联网的时代，所以让你的网站更适应移动平台是将来的必修课。用平板和手机访问网站用户看到的会是不同排版。
76. YouTube: There’s no doubt that YouTube videos are given preferential treatment in the SERPs (probably because Google owns it ):

YouTube:不能质疑的是YouTube视频在google搜索排名中的优惠待遇(可能是因为谷歌拥有它):事实上,不难发现，在Google推出熊猫算法之后，youtube的流量和关键词排名有了显著提升。
77. Site Usability: A site that’s difficult to use or to navigate can hurt ranking by reducing time on site, pages viewed and bounce rate. This may be an independent algorithmic factor gleaned from massive amounts of user data.
站点用户体验：一个站点如果结构混乱，导航混乱，排版混乱。那结果必须是跳出率高，在线时间短，PV低。
78. Use of Google Analytics and Google Webmaster Tools: Some think that having these two programs installed on your site can improve your page’s indexing. They may also directly influence rank by giving Google more data to work with (ie. more accurate bounce rate, whether or not you get referall traffic from yourbacklinks etc.).
使用Google Analytics和Google Webmaster Tools：有些观点说Google会考虑这2个因素，和影响排名相比，更大的作用是影响收录。
79. User reviews/Site reputation: A site’s on review sites like Yelp.com and RipOffReport.com likely play an important role in the algorithm. Google even posteda rarely candid outline of their approach to user reviews after an eyeglass site was caught ripping off customers in an effort to get backlinks.
用户评价：站点在其他网站的评价，如Yelp, RifOffReport, WOT等，也会影响网站的排名。因为这些评分站点Google也是会去爬行，索引并读取内容的。而且这些网站往往是信任度非常 高的，所以悉心维护你的网站的评分也是很有必要的。
