The more I read about PageRank, the less I know... is there any kind of "unofficial" documentation? I'm looking for more than "get lots of high PR backlinks". I've also seen the official explanation of how PR is calculated, but I don't have a graduate degree in math. The reason I ask is, I've read on another forum that the values that Google uses in their updates may be nearly a year old. I don't know what the point of that is, but a lot of people with newer sites who sit through update after update after update saying "why didn't my pages change?" would have an explanation that actually makes sense rather than saying "it's a minor update.... they're just updating a few pages".
That's not really relevant to my question. I'm not looking for opinions on PR or SEO in general. I'm trying to find out something specific about PageRank...
Here is what you were looking for: The official paper from Princeton: http://press.princeton.edu/chapters/s8216.pdf For Google Pagerank: http://ilpubs.stanford.edu:8090/422/1/1999-66.pdf This explains it all: PageRank, search engines, rankings, etc
Thank you for the links... I will have a look at them, but the one is what I referred to in my original messages saying that I don't really have a degree in math. Handy info to have, though... What I was looking for was more about how PageRank is exported to the toolbar. And specifically, why I'm just now hearing that Google updates the toolbar with nearly year old data. If the changes that people make won't be reflected in the toolbar PR for at least a year, it makes it easier to just let it drop and forget about it. Or maybe not, I can be a foolish optimist at times...
Ummm... who said I wanted to sell links? I don't know who would buy them. My sites are pretty low in PR, and I don't think they'll really impress anyone if they were updated. Maybe I just want to know what the value is, maybe?
Why don't check on the following links http: //en.wikipedia.org/wiki/PageRank http: //www.mattcutts.com/blog/whats-an-update/
