The site statistics by Alexa 2.0 include to whom the site is registered, how popular it is, how many sites link to it, and whether it is safe for e-commerce. The technology also offers a list of related sites based on other Alexa user patterns.
Netscape incorporated Alexa technology into in its upcoming Communicator 4.5 suite, as part of the "smart browsing" offerings. A "what's related" feature, developed from a partnership between Netscape and Alexa, provides a drop-down box with an automatically generated list of recommended related sites. The feature relies on servers for Netcenter (Netscape's portal site) for a database of links, which are automatically updated via software that tracks surfers' Web usage.
Alexa is archiving publicly available content on the Web so that users who get a "404 Not Found" error message can view the most recently archived version of an unavailable Web page.
"The Alexa service has been the Web's best-kept secret, reserved largely for those Web surfers who like comparison-shopping the sites they are surfing," Peter Krasilovsky, vice president of research firm Arlen Communications, said in a statement.
