Web Resources
There are three numbers that Alexa reports, reach, page views and overall rank. Reach refers to the percentage of all web users that visited your site. Alexa reports this number as “reach per million users.” For example if Alexa reports a reach of one, it means that on average out of one million web surfers one visits your site. Page views simply measures the average number of pages a surfer examines when at your website. Those sites with a lot of content and targeted visitors tend to generate a larger number of page views. The overall Alexa rank is a combination of the reach and page views numbers such that the larger both of them are the lower the site’s rank will be; for Alexa, a smaller rank indicates a more important website.
On a daily basis, Alexa collects statistics about the number of visitors and page views for every website on the Internet. Actually, it does not have data for all the sites. You see, data collection happens via web surfers that have downloaded and installed the Alexa toolbar for their Internet Explorer browser. When one of these users visits and explores a site, the toolbar sends this information to Alexa’s servers. What this means for webmasters is that only those sites visited by users that have decided to install the toolbar will actually have data collected for them. In addition, since only a rather small subset of all possible Web surfers actually uses the toolbar, the ranking is a statistical average that is not necessarily a true indication of the quality and number of a site’s readers.
