Let\'s start with an explanation of Alexa. Alexa is a free download that works with your browser (it seems to work best with Internet Explorer). Operating in a toolbar or frame attached to the browser, it gives you an indication of how popular a site is (overall rank of web site, based on the number of Alexa visits, which is a pretty good approximation). It tells you about related sites, and offers contact information if it\'s available. Reader reviews and ratings are also a part of the Alexa formula. However, Alexa has languished somewhat under its new parent, Amazon.
