Alexa Internet Inc or more commonly known as Alexa.com is a California based company owned by Amazon.com. The company is globally known for providing internet based commercial web traffic data. Originally Alexa was found as an independent company in 1996 but then it was acquired by Amazon in 1999. American web entrepreneurs Brewster Kahle and Bruce Gilliat were the founders of this company. It was named after the Library of Alexandria, which was considered to be the largest repository of knowledge in the ancient world. The founders dreamt to make Alexa.com the largest repository of internet knowledge, and thus named it so.
The website works in very simple way. The Alexa Toolbar, which is installed on the browser, collects the browsing data and transmits it to the Alexa website. The data here is stored, analyzed, formulated and reported to construct a report of the performance of a website. As of 2013, Alexa.com provides web traffic data, global ranking and other similar information on over 30 million website. The site enjoys over 8.5 million monthly visitors.
Also, the company offered a toolbar which suggests internet users on where to go next, based upon the traffic patterns of its user community. Together with visitors history, the website also gives information about to whom it was registered, how many pages it had, how many other sites linking to it and how frequently it was updated.
Alexa.com underwent a major redesign on March 31, 2009. Now it offers new web traffic metrics, average page views per visit, bounce rate and average time a user spend on the site. Some other inclusions made were visitor demographics, click stream and search traffic statistics. The site implemented these features to surpass its competitors namely Compete.com and Quantcast.com.
