Operations and history

Alexa Internet was founded in 1996 by Brewster Kahle and Bruce Gilliat.[1] The company offered a toolbar that gave Internet users guidance on where to go next, based on the traffic patterns of its user community. Alexa also offered context for each site visited: to whom it was registered, how many pages it had, how many other sites pointed to it, and how frequently it was updated.[2] Engineers at Alexa, in cooperation with the Internet Archive, created the Internet Archive's Wayback Machine.[3] Alexa also supplies the Internet Archive with web crawls. Year 1996 (MCMXCVI) was a leap year starting on Monday (link will display full 1996 Gregorian calendar). ...

Alexa began a partnership with Google in spring 2002, and with the Open Directory Project in January 2003.[5] Live Search replaced Google as a provider of search results in May 2006.[6] In September 2006, they began using their own Search Platform to serve results. In December 2006, they released Alexa Image Search. Built in-house, it is the first major application to be built on their Web Platform. Today, Alexa is primarily a search engine, an Open Directory-based web directory, and a supplier of site information.[citation needed] This article is about the corporation. ...

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. Uniquely, their Web Search Platform gives developers access to their raw crawl data. In May 2007, Alexa changed their API to require comparisons be limited to 3 sites, reduced size embedded graphs be shown using Flash, and mandatory embedded BritePic ads.[7] Year 2005 (MMV) was a common year starting on Saturday (link displays full calendar) of the Gregorian calendar. ...

In April 2007, Alexa v. Hornbaker was filed to stop trademark infringement by the statsaholic service.[8] In the lawsuit, Alexa alleges that Hornbaker is stealing traffic graphs for profit, and that the primary purpose of his site is to display graphs that are generated by Alexa's servers.[9][10] Hornbaker removed the term Alexa from his service name on March 19, 2007.[11] Year 2007 (MMVII) is the current year, a common year starting on Monday of the Gregorian calendar and the AD/CE era in the 21st century. ...

Concerns over Alexa rank information and the Alexa Toolbar

Alexa ranks sites based on visits from users of its Alexa Toolbar for Internet Explorer and from integrated sidebars in Mozilla and Netscape. In addition to their own statusbar extension, Sparky (released, July 2007), there are several third-party extensions for Mozilla Firefox. The Alexa Toolbar, an Alexa Internet product, is a web browser toolbar often used to measure website statistics. ... July 2007 is the seventh month of that year. ... Firefox redirects here. ...

There is some controversy over how representative Alexa's user base is of typical Internet behavior. If Alexa's user base is a fair statistical sample of the internet user population (e.g., a random sample of sufficient size), Alexa's ranking should be quite accurate. In reality, not much is known about the sample and possible sampling biases. Alexa itself notes several examples (here and here) A known source of bias is the self-selecting, opt-in nature of Alexa traffic tracking software installation, but the significance of this bias on rankings is not reported.[12] A sample is that part of a population which is actually observed. ... In general, a sample is a part of the total, such as one individual or a set of individuals from a population (of people or things), a small piece or amount of something larger, a number of function values of a function, or part of a song. ...


Another concern is whether Alexa ratings are easily manipulated. Some webmasters claim that they can significantly improve the Alexa ranking of less popular sites by making them the default page, by exchanging web traffic with other webmasters, and by requiring their users to install the Alexa toolbar; however, such claims are often anecdotal and are offered without statistics or other evidence. A traffic exchange is a type of website on the Internet, which provides a service for webmasters to exchange of traffic. ...


Statistically speaking, based on the process of data acquisition through the toolbar and other limited and proprietary means, which is analogous to non-scientific sampling, the representative accuracy of Alexa's traffic and rank statistics is inversely squared in proportion to the actual traffic. In other words, the less actual website traffic, the higher the statistical inaccuracy increases exponentially. Of course, this has not been proven (and cannot be proven without access to Alexa's raw data), but can be demonstrated with a simple experiment. Start a new website on a new domain, or find one that is known to have virtually zero traffic with server-side traffic stats. After a baseline of zero traffic has been demonstrated for several months, begin loading the website daily with a browser that uses Alexa toolbar. Very quickly, the stats will rise above NA (or no data available) to levels that will appear to be higher than one visitor per day. After several weeks of this, where the trend has been marked, ask several friends to begin visiting that site daily with an Alexa enhanced browser. Then, even when it can be shown through webstats that only a small number of visits occur daily, the website will appear in Alexa to be on a comparable level with sites that are said to have thousands of hits.[citation needed]
