Many bloggers hope for a high PR, it is important when wanting to review other sites and sell link space for business blogger and it looks good. But really, regardless of all those things, at the end of the day it means that people are linking to you, and that is a great feeling and that is what really helps you rank in the search engines. Google PR is just a little badge to say: You have links.
Sites without PR can rank higher than sites with high Google PR, but often this involves using massive link building strategies or some other approaches that I won’t bother discussing, as generally sites without Google PR are very new domains as newer sites don’t have links. You can’t link to something that did not exist a few months ago, after all. And Google search rank is based greatly on the number and quality of sites linking to yours.
I had mentioned this on another blog as comments, but I thought I would discuss this here on my blog as well with regards to Google PR. I don’t plan on getting very technical and mathematical, as really we cannot be sure of all the factors involved in how Google calculates PR, which is actually makes it a little exciting because if they did tell us, that would take all the mystery out of it and that would make life very boring.
But generally it is considered that Google PR is calculated along the lines of:
PR(A) = (1 – d) + d * SUM ((PR(I->A)/C(I))
Just kidding! I said Google PR made easy, right?
The Google PR of a page is calculated by the number of pages pointing to your page. For every page that links to yours, the PR is by the number of links off that page. Then the PR that goes to your page is divided up among the # pages linking off your page.
During the last PR update I had a number of pages and sites that were affected by the PR update, and I had tried many future PR predictor tools on many pages and sites. I found generally they were within 1 PR point of the actual PR of the page after the last update. This is useful, and it can be a relatively accurate indicator but not without flaws.
That being said, I started to think about the movie: Cube. Have you seen it? If you have not do not keep reading because I am about to give away the punchline.
So these people are trapped in a cube, and it turns out one of the guys trapped in this cube of death actually was part of the large army of people who worked to design the cube of death and mystery. So no one really knew what they were making, they were commissioned to all play small parts in the creation and building of it, but the right hand did not know what the left hand was doing, and then imagine thousands of hands. Get it?
Well, what if that is what Google is like? I wonder how many people who work at Google, even at the higher levels, could actually tell you how the search engine works. It could be in fact that very few know because it involves so many people and areas. Maybe the people who work at Google are like the people who built Cube, except without the cube of death and instead a search engine… ?
