Problems with the Alexa Rank

[seointerest]

Alexa ranking is always towards websites which have a large webmaster/tech audience. This is because webmasters are much more likely to have the Alexa toolbar installed than websites whose visitors are unaware of Alexa.

As such, many believe that Alexa is a vastly inaccurate method of measuring a website’s reach, traffic and potential. I don’t disagree.

I believe that Alexa is a silly way to measure web traffic but unfortunately, in it helps you in measuring the value of advertising on your website.

IS there someone here who contradicts with my views?
