I’ve always said that Alexa data is a nice tool, but doesn’t give any serious data that can be relied on.
Matt Cutts comes to the same conclusion, after Alexa suggested his blog’s traffic gets 25% the level of Ask.com – yeah, right.
…there is some serious webmaster skew in the Alexa data. There is no way that I have 1/4th the daily reach of Ask. I think my site gets a little boost because tons of SEOs install the Alexa toolbar.
