Alexa is not important. It doesn't provide any really accurate data, it is very easy to manipulate, and the only advertisers who are going to use it generally are not going to be spending much on your site.
SEO Moz rank is not the same as Alexa, and in my opinion is more accurate than page rank when it comes to judging the prospective value of a website.
My advice, focus on your analytics, not meaningless metrics.
