Alexa
An Amazon.com company that was originally founded in April 1996 that uses information collected from users who have the Alexa browser Toolbar installed to build a more intelligent Internet and traffic ratings. Alexa is a great method to determine general statistics for your web page and blog and one of the best ways to compare your site with your online competition. However, keep in mind that Alexa traffic ratings are only based on users who have the Alexa Toolbar installed. If you want exact traffic data for your website, we suggest Google Analytics.
