I have to object with Arrington's analysis of Alexa and scold him for yet another blog article about how Alexa is inaccurate and needs a "re-work".

Alexa is just a tool, no more no less. We all know HOW Alexa gathers data, and we all know the flaws. It should be used along with Compete and Comscore to gain an overall picture of where a webiste ranks in comparison to other sites in it's field. Just like your FICO score is calculated from 3 credit reporting agenncies, your overall website rank is the summation of different traffic and influence measurements.

I can find flaws in any web service. How easy it is to show a bad rank order in Google? How easy is it to spot inaccuracies with the Technorati Top 100? Singling out tools and highlighting how inaccurate they are when you fully understand how it collects data is foolish. It also means that you can't discount a tool completely just because it isn't perfect. Will I post a blog article about how Google is use
