Top 5 SEO Lessons About Google Page Rank

As I was putting together my presentation for OMS next week, I decided to do some research into some old patents for fun (which proves that although I am a heavy metal guitarist and supposed to be cool, I have no choice but to admit I have become an SEO geek..lol). I did some reading on Hilltop, Topic Sensitive Page Rank and a couple others. But one document that I found that I have not read before is called: "Page Rank - A Circuital Analysis". I found this article to be very interesting because it provides some scientific basis for what I have always believed to be best practices based on the original Page Rank algorithm.

Here are the top 5:

1) The same content divided into many pages, yields more Page Rank than if the content was located on one page.

2) External hyperlinks should be limited.

3) External hyperlinks should be limited to pages with small Page Rank or to pages having many internal links.

4) Links to links should be avoided (pages that don't contain hyperlinks).

5) External hyperlinks to sinks should be limited to pages with small Page Rank or to pages having many internal links.

Now before anyone wants to flame me for discouaging external linking, that's not what I am doing. I am merely saying that you want to decrease the amount of PR that flows through external links or to sink pages by incorporating as many internal links as you can on pages that do link externally. It's the same concept as using no follow to sculpt your Page Rank. You want PR to flow to your most important pages (rather than your privacy policy for example), and you want to make sure that you limit whenever possible, the amount of Page Rank that you allow to bleed from your site. For those unfamiliar with how Page Rank works and the fact that it is a recursive function, it is hard to describe how this takes place. But if you read the references that I have linked to, it should become apparent how this takes place.

Many people in todays search world think that Page Rank is not important. That is simply not true. But you certainly have better things to do than chase links with high PR values because there are another 100 algorithm metrics which are used in Google's overall formula (one of which is links to external sites, meaning that linking to good resources that are useful to your users is a good thing). However, maximizing your Web structure to take advantage of your existing Page Rank properties makes good sense and is good SEO.

Can't you prevent "loosing" pagerank with no-follows? This should be #1.

Regarding outgoing links, Google use them to get an idea of what the page is about, so I have to disagree with taking them out from the page.

Well again man, I am not suggesting that you don't link to good resources. I am suggesting that when you do, it is good to make sure that there are plenty of internal links on the page in order to decrease the amount of PR that passes out through the link.

Linking to quality sites like wikipedia, etc is also admired by Goolge. One another important factor is the internal linking, that should also be maintained, i.e. it should also not exceed a specific number!

blogoxide if you are refering to the old 100 link limit that Google used to recommend, it's a bit outdated now as Google indexs more than 100K.

Facebook has made its content (groups, wall posts, events, discussion topics, etc.) accessible to search engines. This is an excellent opportunity for those in pursuit of SEO success.

So PR should be affected too what do you think?
