SEO Explained Part Two

Page Rank is probably one of the least understood concepts in the internet marketing world. The reason being, not even the experts know exactly how it works. Page Rank is only used by Google, however, Google have a 70-80% market share so it is very important. The problem comes when you realise that only Google truly know the exact formulae to calculate Page Rank, and they are not telling. So those of us who need to know wean as much as possible from many sources regarding the overall rules that are fairly plain. And we have come up with this.

PR(A) = (1-d) + d(PR(t1)/C(t1) + … + PR(tn)/C(tn))

This equation calculates the Page Rank of a page. This is covered in detail in our training seminars, sufficed to say that the more pages you have which are correctly interlinked the higher your potential Page Rank. Also the more inbound links you have the higher your Page Rank. And the higher the Page Rank, the higher up the search results. Of course it is more complicated than this; however, it gives you a basic understanding.

So why is this something you might want to know? As a designer it is important to build a website with this equation in mind. How many pages, what structure, how to link them? These questions should influence every part of your design; they should be key concepts in designing the architecture of the site, specifically navigation.
