When you install the Alexa Toolbar, the Web sites you visit will be tracked; this tracking helps to increase the relevancy and accuracy of Alexa’s data. The lower Alexa number is the more traffic site receives. Alexa rankings of less than 100,000 considered to be good.
Alexa numbers tend to slant in favour of technology or Webmaster-oriented Web sites while the number of technology site readers have the Alexa Toolbar installed is larger than the number of average Internet users who have Alexa Toolbar.
