Alexa Internet, often referred to simply as Alexa, is a Web traffic information, metrics and analytics provider.
Visitors to the Alexa website can:
- See data for Alexa Top Sites.
- Search to see traffic data, such as ranking and bounce rate, for websites that aren't included in the top-ranked sites.
- Download the Alexa toolbar, which allows them to see statistics for websites as they browse and records their browsing data for inclusion in Alexa statistics.
- Create a custom toolbar, which can be shared.
Alexa Pro, available in three levels, offers more sophisticated tools and analysis as well as services such as periodic site audits.
Alexa was founded by Brewster Kahle and Bruce Gilliat in 1996 and acquired by Amazon in 1999. Kahle and Brewster named the site in honor of the Library of Alexandria, one of the largest libraries of the ancient world.
Alexa operates as a wholly-owned subsidiary of the parent company.
