Alexa Internet was started in 1996 as a content recommendation engine. It watched user browsing habits and, through a toolbar, offered suggestions and recommendations for users where they should check out next.
In 1999, Amazon bought Alexa.com and built it into an analytics powerhouse. They worked directly with Google, DMOZ, the Internet Archive, and a variety of other analytics providers. They also offered a global ranking of websites based on website traffic numbers. The “Alexa Rank” was useful to monitor website traffic and it sources.
