Alexa排名英文介绍|什么是Alexa Rank

我们用英语来介绍一下Alexa Rank：

Alexa's popularity has been growing by leaps and bounds over the last several years and none of it would be possible without the Alexa Toolbar. Good reasons to install the Alexa Toolbar:

1. The toolbar provides quick and easy access to the data that you expect from Alexa, including rankings, related links and more.
2. You can help improve the data by installing the toolbar. The more people use it, the better it gets.
3. Alexa is free.

Alexa is a community of users improving the Web for everybody. Just by using the Alexa Toolbar you are ensuring that everybody has access to a free and impartial source of traffic information. If you don't have the toolbar already, what are you waiting for?

The new toolbar, version 7.1, is a minor revision that includes some design improvements as well as one nifty new feature... it automatically shows a red or green arrow indicating whether the site's traffic rank is improving or declining.

For those of you that already have an Alexa Toolbar installed, thank you. Your Alexa Toolbar should auto-update within the next week or so.

通过以上的英文介绍，我们了解到Alexa是一家专门发布网站世界排名的网站。以搜索引擎起家的Alexa创建于1996年4月，目的是让互联网网友在分享虚拟世界资源的同时，更多地参与互联网资源的组织。2002年5月Alexa放弃了自己的搜索引擎转而与Google合作。Alexa每天在网上搜集超过1,000GB的信息，然后进行整合发布，现在他搜集的URL数量已经超过了Google。下图是他们自己给出的一个信息量比较图。纵轴为已有的URL地址数量，以十亿为单位。也就是说在量上，Alexa位居世界四大搜索引擎第一位，已超过35亿。
