Alexa Traffic Rank: What It's And Why You Should Care (or Not)

Alexa is an Amazon owned company that's famous for its public traffic ranking service by way of its website. Internetsite promotion guides usually make a giant deal about learn how to enhance your Alexa rating because a high place is often associated with high profits. As a new webmaster, you should understand a couple of very important factors about Alexa's service. This article will clarify what the information collected by Alexa imply and then describe why you need to care or not.

There are three numbers that Alexa reports, attain, page views and overall rank. Attain refers to the percentage of all internet users that visited your site. Alexa reports this number as "attain per million users." For instance if Alexa reports a reach of one, it means that on common out of one million net surfers one visits your site. Page views merely measures the typical number of pages a surfer examines when at your website. These sites with quite a lot of content material and targeted guests tend to generate a larger number of web page views. The general Increase alexa rank rank is a mix of the reach and page views numbers such that the bigger each of them are the lower the site's rank might be; for Alexa, a smaller rank indicates a more essential website. Alexa reports these numbers for every day, one week and three month averages and the overall change over a three month period. So, how does Alexa collect these information?

On a daily basis, Alexa collects statistics in regards to the number of holiday makers and page views for each netsite on the Internet. Actually, it doesn't have information for all the sites. You see, information collection happens through web surfers which have downloaded and installed the Alexa toolbar for their Internet Explorer browser. When one in every of these customers visits and explores a site, the toolbar sends this data to Alexa's servers. What this means for webmasters is that solely these sites visited by customers which have decided to put in the toolbar will actually have data collected for them. In addition, since only a somewhat small subset of all attainable Net surfers really makes use of the toolbar, the ranking is a statistical average that's not necessarily a real indication of the standard and number of a site's readers. The truth is, the number is really inaccurate for sites with a small number of tourists and Alexa admits that this is true for those sites not in the high 100,000.

To make matters worse, the toolbar is only available for Internet Explorer. After all, IE is the browser used by the majority of Internet customers with knowledge showing that it's used by about eighty three% of them ( This will not be a problem unless your viewers is more prone to be in the other 17% of surfers, i.e., those who choose to make use of Firefox, Safari, Opera or another different browser. For example, is a expertise news site with an audience that's known to be very anti-Microsoft; Slashdot's motto is "News for nerds. Stuff that matters." One expects that most of its customers would use any browser aside from IE and in reality it was not too long ago posted that an estimated 65% of Slashdot's readers use a browser other than IE. As of this writing (July 12, 2006), Slashdot's ranking was 176 with a attain of 5450 per million surfers. Slashdot is known for something called the "Slashdot impact" that's when a story on the entrance page links to a site, it receives so many guests that the servers often should not able to deal with the sudden enhance in traffic. In different words, I would expect that Alexa's rank is definitely an underestimate of Slashdot's true rank.

From a statistics viewpoint, Alexa's rank cannot be regarded as an unbiased statistical measure. The sample of individuals used by Alexa for amassing data isn't a randomly selected set but somewhat it is biased towards customers of Microsoft Windows and Internet Explorer in addition to those that are keen to put in the toolbar and undergo Alexa details about their browsing behavior. If your audience is much like Slashdot's then do not count on accurate results. Anticipate the identical in case your viewers contains people who are professional-privacy and would never install a toolbar that calls home making their browsing conduct known to a large corporation.
