Alexa is a free advertising-supported Web navigation
service. It works with your browser and accompanies you as you surf, providing useful
information about the sites you are viewing and suggesting related sites.
Alexa Internet was created from a novel vision. A vision of navigation that
learns and improves over time with the collective participation of its users. We all
experience the gaps in navigating and finding information on the Internet as it is used
today--frustrating keyword searches that turn up hundreds or thousands of web pages and
sites, very few of which are of any interest.
What if we, as a community of users, could effortlessly pool our
collective experience and add human intelligence to navigation? What if we could fill in
those gaps? It is a radical concept and it is our goal to make it real, and we invite you
to join us in this effort.
What we are doing can change the way we use the Internet forever.
The Alexa service is the first Internet software product that learns from people. This
intelligent navigation service provides a continuous source of relevant recommendations of
where to go next on the Web. Alexa works in parallel with, and independently of Web
browsers, and is displayed as a toolbar on the user's desktop. The more people use Alexa,
the more we all benefit.
Alexa Internet gathers, manages and analyzes multi-terabyte
collections of information to make access and navigation easy for everyone. Alexa's
technology provides a new approach to a major problem with the Internet, the inability to
quickly and easily find information users know exists.
Founded in April 1996 by Brewster Kahle and Bruce Gilliat, Alexa
Internet has harnessed the collective wisdom and experiences of the entire Internet
community and transformed them into the Alexa service.
Alexa is available as downloadable software for Microsoft Internet
Explorer 4.0 and Netscape Navigator 3.0+ and Microsoft Internet Explorer 3.0+. A alpha
test version is available for Macintosh. The free software is available at their site with
detailed instructions and examples.
