Here is some information on Alexa coutesy of Wikipedia.

California-based subsidiary company of Amazon.com, that is best known for operating a website (www.alexa.com) that provides information on the web traffic to other websites. Its premises are in Building 37 of the Presidio of San Francisco.

Founded in 1996 by Brewster Kahle and Bruce Gilliat and backed by Jacqui Safra's Etoile Investments as a commercial offshoot of the Internet Archive, Alexa Internet created related links derived from user behavior (a form of collaborative filtering) for users of the Internet Explorer and Netscape Navigator web browsers. Engineers at Alexa created the Internet Archive's Wayback Machine. Alexa also supplies the Internet Archive with web crawls. It should be noted that Alexa does not collect information on users of Mozilla Firefox, Opera, or other minority web browsers.

Alexa collects information on Web usage through the Windows-only application, the Alexa Toolbar. This allows them to provide statistics on web site traffic, as well as related link information. The Alexa Toolbar has a bad reputation with anti-spyware programs, as it collects information on search habits.

In 1999, Alexa was acquired by Amazon.com for about $250 million in Amazon stock. The "site info" link on the Alexa site lists related links for websites and also records how much web traffic they receive. Alexa began a partnership with Google in spring 2002, and with the Open Directory Project in January 2003. Today, Alexa is primarily a Google-based search engine, an Open Directory-based web directory, and a supplier of site information.

Alexa also provides "site info" for the A9.com search engine and for Alexadex.com.

In December 2005, Alexa opened its extensive search index and web-crawling facilities to third party programs through a comprehensive set of web services and APIs. These could be used for instance to construct vertical search engines that could run on Alexa's own servers or elsewhere.
