This article was written by Old Welsh Guy Owner of Umbrella Consultancy, an Internet Marketing Consultancy based in the UK How can a deep page have a higher PR than the home page? Simple, it is ALL about link structure. Link structure (i prefer navigation structure as a phrase when talking about within a site). so lets go to the top. First off, understand that a page can vote (not transfer, as it votes and keeps PR) a page can vote, up to 85% of the value of its own Page rank (PR). This value is divided between the outbound links it has. So page 'A' is a pr4 page with 10 outbound links (assuming they are all internal links to the site because PR travels more freely within a domain than it does across the web). so 10 links divided by pr4 X 0.85 = a link value of 0.34Pr per link. Ok so there we have it. It links to every page on the site, as do all the others. so in a flat navigation structure like this, every page on the site will have the same PR (in theory).
BUT, lets say that there is a page on the site that has a fantastic bit of content that many many people link to. This site will ALWAYS be AT LEAST 015% higher in PR than the rest of the site, as it can only vote 85% of its own PR out. Normally most people will link to the home page, but not always. Ok Another way to manipulate PR, and it is called daisychaning. Page A Page B Page C Page D
Page a is a pr4 It has one link on it to page B which has one link on it to page C which has one link on it to page D. Every page in the site links to page a, b, c & d. They however only link to each other in daisy chain mode. So page a will pass ALL its available vote to page B (this will not be = to .85 however as other dampening factors will kick in due to the small amount of outbound links. But lets assume it passes say 10% This makes Page b PR$ +.10 of A = PR 4.4 this then passes 10% on to c making which passes on 10% onto d and so on, with the PR compunding along the daisy chain. The other way to do it (which is better although a waste of time as PR is a load of balls anyhow). is to have page a linking to B, C, D, E, F, G & H b linking to c,d,e,f,g,h, c linkng to d,e,f,g,h, and so on.
This will allow more PR to flow out of the early pages, and along the daisy chain. I hope this has explained it better although somehow I doubt it
