Are alexa rankings worth anything? Three of my websites are ranked in the 150,000 range. A fourth website of mine which has THREE TIMES THE TRAFFIC of any of the three sites i just mentioned is ranked at around 750,000 on alexa....
Alexa doesn't mean much unless you are referring to the top 10k or so. The ranking higher than that are very easily manipulated. If you install the toolbar you will usually see your site break the top 100k in a week or two.
Webmaster sites usually rank much higher on Alexa because their more likely to have users with the toolbar.
