Alexa, founded in April 1996, is a web information company. Alexa ranks sites based on tracking information of users of its Alexa Toolbar for Internet Explorer and from integrated sidebars/plugins in Netscape and Mozilla.
The question is, why is Alexa ranking so important? That's because Alexa data is still being followed by numerous affiliate programs and other services in order to determine the quality of the site. That list of sites include Text Link Ads, Review Me, Sponsored Reviews etc.
The Alexa data is usually represented by a numeric rank and an Alexa graph. But the graph is shown only for sites which are within the first 100,000 ranking. And getting into top 100,000 is not only difficult but is also a time consuming process as Alexa calculates the ranks using an average of last 3 months. So unless your site is in the top 100,000 list on Alexa, then you would be greeted with a blank graph saying "Not in top 100,000".
But here's the trick. Even if your site is not listed in the top 100,000, you can still view the graph of your site. All you need to do is, take the Alexa graph of any other site, take mine if you want to, and compare your site with that graph, and you would get a beautiful graph of your site along with the graph of that other site.
Comparing the sites is pretty simple. Go to the traffic ranks page of your site. Just below the graph you would find 5 text boxes, one of them containing the URL of your site. Write the URL of the other site with which you want to compare your site one of those blank text box. Then click on the "Compare Sites" button and enjoy the view, but don't forget to subscribe to The Chronicles of R to learn more such useful tips and tricks.
