Alexa rank


ALEXA RANK

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 firefox fans or any other browser users. But there are over 10 million Alexa Toolbar users who make it a recognized measurement
·        The traffic rank is based on three months of aggregated historical traffic data from millions of Alexa Toolbar users and data obtained from other, diverse traffic data sources, and is a combined measure of page views and users (reach). As a first step, Alexa computes the reach and number of page views for all sites on the Web on a daily basis. The main Alexa traffic rank is based on a value derived from these two quantities averaged over time (so that the rank of a site reflects both the number of users who visit that site as well as the number of pages on the site viewed by those users). The three-month change is determined by comparing the site's current rank with its rank from three months ago. 
·        Reach measures the number of users. Reach is typically expressed as the percentage of all Internet users who visit a given site. So, for example, if a site like yahoo.com has a reach of 28%, this means that of all global Internet users measured by Alexa, 28% of them visit yahoo.com. Alexa's one-week and three-month average reach are measures of daily reach, averaged over the specified time period. The three-month change is determined by comparing a site's current reach with its values from three months ago.
·        Page views measure the number of pages viewed by site visitors.  The page views per user numbers are the average numbers of unique pages viewed per user per day by the visitors to the site.
·        The Trend graph shows you the site's daily traffic rank, charted over time. The daily traffic rank reflects the traffic to the site based on data for a single day. In contrast, the main traffic rank shown in the Alexa Toolbar and elsewhere in the service is calculated from three months of aggregate traffic data.
·        The movers and shakers list is based on changes in average reach (numbers of users). For each site on the net.they compute the average weekly reach and compare it with the average reach during previous weeks. The more significant the change, the higher the site will be on the list
·        They then normalize the data on demographic distribution of site visitors. Geographical distribution as such to represent those who do not use Alexa toolbar
