MozRank reflects the link popularity of a website or a blog, thus it provides details of how important a given website/page/blog is on the Internet.
MozRank is earned by having a high number of quality inbound links from other websites/pages/blogs that has also earned popularity via MozRank.
Scoring is scaled between 1 as the lowest score and 10 as the highest, but unlike google page rank, it’s much easier to improve your rank from 3 going to 4 that 8 to 9.
I just learned that my blog www.ronsilvoza.com have just earned a MozRank of 4.4, that surely is a Great achievement for someone like me who doesn’t care much detail on SEO. lol
