作为Google搜索引擎排行最重要指数之一，PageRank一直受到业内关注，每次PageRank大规模升级都会引发对Google搜索引擎排名新规则的重新分析。 近日，Scott Vivian总结了一份PageRank达到9以上的网站列表。Scott Vivian表示，Wiki百科曾经有一份相关列表，但是因不知原因被删除，因此下表中的网站均为采用搜索http,www,the,a等常见关键词来获得。 PageRank 10网站： 也是很多人的必备收藏，目前仅有18个网站入围，例如： * Adobe.com * FirstGov.gov * Google.com * Real.com * W3.org * StatCounter.com PageRank 9网站： PageRank达到9的网站数量要远高于PG＝10的数量，超过百个，有趣的是，其中不少网站其实已十分古老且并不经常更新，例如AltaVista。根据分析，其中部分老牌站点虽然现在已颇为没落，但是“上镜率”颇高，尤其是在讨论到互联网历史等问题时，例如： * A9.com * About.com * ACM.org * AlltheWeb.com * AltaVista.com * Excite.com PageRank 10 * Adobe.com - Adobe Systems, software company * Apple.com - Apple Computer, also houses the iTunes Music Store * Blogger.com - Blogger, a weblog publishing tool * CSAIL - MIT’s Computer Science and Artificial Intelligence Laboratory (*) * Energy.gov - United States Department of Energy * ERCIM.org - European Research Consortium for Informatics and Mathematics (*) * FirstGov.gov - U.S. government portal * Google.com - Google, search engine that assigns PageRank * Keio.ac.jp - Keio University, Tokyo, Japan (*) * Macromedia.com - Macromedia, software company * NASA.gov - NASA, U.S. government agency for the space program and aerospace research * NSF.gov - National Science Foundation, U.S. government agency for scientific research * NYTimes.com New York Times, news site * Real.com - RealPlayer, music, video, games * StatCounter.com - tracking service * W3.org - World Wide Web Consortium o http://validator.w3.org/ o http://jigsaw.w3.org/css-validator/ * WebStandards.org - Web Standards Project * Whitehouse.gov - The White House (*): These websites are linked from W3.org, which automatically gave them a PageRank of 10, even if they do not have much traffic or incoming links.
