PageRank (PR) is Googles method of calculating a web pages relevance and importance through the quality of sites linking to it.
The precise details of the algorithm are kept secret and Google continues to “enhance” its performance. It is seen as an important indicator as to the popularity of a site and thus its value to potential advertisers.
It can become a bit of a holy grail with developers concentrating more on PR than getting the traffic they need. Small businesses in particular should concentrate on getting customers first. If successful Page Rank will follow.
