網頁排名 page rank
....Moreover, it has upgraded its search engine functionality, and developed a new ability to share status updates with the entire network in real-time. Google's page-rank search technology is good, but it's still pretty primitive.
在上面的報導中，page-rank就是指「網頁排名」或者「網頁等級」，一般寫做page rank。Page rank是 Google 中表示網頁重要性的綜合指標，通常被稱為PR值，一共10級，級別越高則證明該網頁越重要，一般認為PR高的網頁會有更大的機會排在Google搜詢的前列。
有時，為了提高page rank，幕後操作者會大量發佈junk link（垃圾連接），合作網站之間也會進行link exchange（鏈接互換）。為了提高網站的搜尋效率，還會進行SEO（Search engine optimization（搜尋引擎優化）。
文中的real-time則是指「即時」，例如real-time display（即時播放）， real time information（即時信息）。Twitter的real-time search（即時搜索）在推出之後立即受到吹捧。

The famous Google PageRank comes with the Google Toolbar. The Google PageRank ranks a page on a scale of 0 to 10 where 10 is the highest. Google PageRank is based on several factors including number of in-bound links (other web pages that link to web page which is being ranked). Google.com carries a PageRank of 10 and so do Yahoo.com and MSN.com (Actually, the page rank of the latter two keeps shifting from 9 to 10). Google PageRank is available on the Google Toolbar.

Though, "Googlerankings.com is in no way affiliated, sponsored or in any way the property of or responsibility of Google.com.", it's still a great service. What I like about this site is that one can enter a set keywords and find out how a web site ranks in Google. However, I find that the ranking reported by the site are a few positions lower than the actual rank one sees when searching on Google. For example, my site www.biotechdesk.com ranks third on Google.com for the keyword "biotechnology india", however, GoogleRankings.com reports its rank as 7th. Similarly, for the keyword "biotechnology consultancy" my site gets the 6th rank on googlerankings.com while its actual rank when searched for on google.com is 4th.
Note: The rank of a web site for a particular keyword keeps on changing on the Google search engine. The above info was obtained on 6th July 2004.
