Alexa Information

Alexa Rank is a relative measurement on how popular a web site among the Internet community. Alexa is relative because it depends on the data of Alexa Toolbar users. And also Alexa Toolbar is only for Internet Explore which means it doesn’t count growing group of Firefox fans or any other browser users. But there are over 10 million Alexa Toolbar users who make it a recognized measurement.

Alexa orders web sites according to Alexa Traffic they get. That means a site with a rank of 1000 gets more traffic than a site with rank of 1001 according to Alexa, of course.

How Alexa Rank Is Calculated

Alexa Rank is calculated considering how many Alexa Toolbar users visited a certain web site and how many distinct pages they viewed in that site over a period of 3 months. Below is the Definition from Alexa itself,

Alexa’s traffic rankings are based on the usage patterns of Alexa Toolbar users over a rolling 3 month period. A site’s ranking is based on a combined measure of reach and pageviews. Reach is determined by the number of unique Alexa users who visit a site on a given day. Pageviews are the total number of Alexa user URL requests for a site. However, multiple requests for the same URL on the same day by the same user are counted as a single pageview. The site with the highest combination of users and pageviews is ranked #1.

Alexa’s traffic rankings are for top level domains only (e.g. domain.com). We do not provide separate rankings for subpages within a domain (e.g. www.domain.com/subpage.html) or subdomains (e.g. subdomain.domain.com) unless we are able to automatically identify them as personal home pages or blogs, like those hosted on Geocities and Tripod. If a site is identified as a personal home page or blog, its traffic ranking will have an asterisk (*) next to it: Personal Page Avg. Traffic Rank: 3,456*. Personal pages are ranked on the same scale as a regular domain, so a personal page ranked 3,456* is the 3,456th most popular page among Alexa users.
