I was chatting with a couple of my best SOE friends this afternoon, and they were stressing the importance of getting as many Page Ranks as possible for client’s websites.  This is something that I have long advocated, and I was glad to see that other SOE people have come around to the idea.

Often, people who are new to the SOE world of meta tags and vertical semantic integration really struggle with what Page Ranks are and why they need them.  In my introduction to SOE seminars, I explain the importance of Page Ranks in the following mnemonic, which has served me well:

To get a page to rank, get Page Ranks

Basically Google has 2 different categories of Page Rank.  Basic and Green.  There are 10 different types of Basic Page Ranks and each of these have different properties.  The exact blend of Page Ranks that your site gets from the rest of the websites determines the Green Page Rank score, which is used to decide exactly where it should rank, and what it should rank for.

The 10 different flavours of basic Page Rank are as follows:

Page Rank 1 – User Friendly

Page Rank 2 – Correct Spelling

Page Rank 3 – Meta Keywords Present

Page Rank 4 – Page has a clear semantic latency

Page Rank 5 – Interesting Content

Page Rank 6 – Useful (eg How To Page)

Page Rank 7 – News type website

Page Rank 8 – Highly SEO’d Page

Page Rank 9 – Secret

Page Rank 10 – Website owned by a Googler / Major Government

The Page Rank of 9 is a secret known only by staff at Google, although it is thought to apply to groups of web pages, and be calculated via a pagination probability vector.

Google assesses the blend of basic Page Ranks that link to a page, and then assign it a secondary decimal value which is the green Page Rank that allows it to rank websites.  This  can also be seen in the Googler tool kit as a green bar (incidentally, green is Sergey Brin’s favourite colour):

How Google uses basic Page Ranks to calculate the Green Page Ranks for a page

How Google uses basic Page Ranks to calculate the Green Page Ranks for a page

Once the googler has done the calculations about how many green page ranks a particular page should be awarded, this figure is stored and then used every time Google has a search for one of the keywords on the page.  All of the results are simply ordered in terms of the number of green Page Ranks that the websites have.

Getting more green page ranks can be quite tough, but asking for links from other websites that also have a lot of green page ranks to share is a good method. It is also important to get a lot of basic page ranks that are of the same type as your website, so if you have a news website, it is a good idea to get lots of other websites with Basic Page Rank scores of 7 to link to you.

Happy optimising.
