How Google Calculates Page Rank (PR)... Damn!

OK you tricked me, I thought

OK you tricked me, I thought that article was going to be in English. It was in maths. Here have some of my Advil. Or M & M's, work much better.

How would any normal person

How would any normal person (someone BESIDES Charlie on "Numbers") understand any of that? Kudos to the "head hurt" comment.

To sum it up...

Yeah, what a pain eh?  But quite interesting.

The main points I got from this are:

1. The maximum PR a page can have is the # of pages on that site
2. The strenght of the passing of PR to another site via an outbound link is inverstly proportional to the # of outbound links on that page
3. To add on to #2... that relationship is most likely on a logarithmic scale
4. To sum up #2 and #3 in layman terms, the more outbound links on a webpage the less each link "counts" - I imagine this is part of how Google countered all the link farms (translation, the more links on a page, the less meaningful they are)
5. Furthermore... a webpage with a PR of 6 containing 10 links will pass more PR than a webpage with a PR of 5 containg 10 links (this is the whole "logarithmic scale" thing)
6. Intra-linking (linking within your own pages to other pages on the same site) is vitally important to your PR - you can drastically improve your PR or you can hurt it...

I think those were the main takeaways.

To summarize (to dumb it down even further):

• The maximum PR of a website is limited by the # of pages it has
• Don't forget to intra-link your pages
• More outbound links on a page means each outbound link carries LESS weight

Anything else?

I'll go out on the "Geek" limb

I think it was good information, even if you have to read each sentence 3 or 4 times.  I think Raymond's summaries above are mostly correct, with the caveat that I am reading his point number 5 a bit differently then the article - but that may be a misunderstanding in my head.

However, what I do find very interesting is the concept of Raymond's point #6, the intra-linking seems to be crucial, and explains why "Silo building" sites and pages seems so effective and important.  It also gives me new thoughts when desigining and laying out pages, links and site structure.

The only thing I would add to Raymond's "dumbed down" list is careful planning of intra-linking can have profound effects on specific pages in your site.  A great way to add SEO "emphasis" to certain key pages.

Thanks Raymond. I don't know

Thanks Raymond. I don't know about 'dumbing it down' but turning it into English instead of maths, thanks.  I got the gist of it, but boy, it was hard going.
