Basic PR question...

[CrapDice]

Hey everyone!

My question is basic and straight forward.

If I have a link to my site from a page ranked 0 however it is from a site where the site's index is ranked, say, 5 -- how does this equate to the value of my link?

Is it seen as a link from a 0 page or are other factors, such as the index PR, factored into the algorithm?

Thank you for any insight you may provide.

Learning,

CrapDice

It's difficult to tell the real PageRank value, the bar is just a guide.

According to Google's research paper "The Anatomy of a Large-Scale Hypertextual Web Search Engine", the figure is calculated based on the page that links to you. However, there may be other new calculations added since then, based on context, age of the link, etc.

PR has less value nowadays. When doing link exchange look for the relevancy of the site than it's PR.

Do link exchange and one way link as Janna said choose a relevance site.Which is additional points in your web site.

PR, less value nowadays? Is this true? How come that others are waiting for PR update if PR has less value? hehehee i think it's because google has different algorithm in terms of PR now....

The calculation of the value to your link is directly propotional to the the quality of the site linking to you, its basically the quality link and the respective popularity funda buddy rather than the PR value.

According to patents that mention PageRank, the basic mathematical formula hasn't changed. But I expect it to have a few possible modifiers:

1. If a Google is in the middle of a PageRank iteration and discovers a new page, instead of restarting the iteration it takes an educated guess.

2. If Google doesn't trust the link (e.g. if its in a sitewide footer with keyword-loaded anchor text, exchanged link footprint is obvious), the PageRank may be devalued or nullified completely. Proof? When Big Daddy was released there was a surge of supplemental results complaints. That was due to Google modifying its crawling/indexing behavior (i.e. pickier indexing using minimum PageRank threshold) and becoming more aggressive with link devaluation.

2a. If Google thinks a page is selling links, it loses its ability to pass PageRank, or so I've heard.

3. I remember Bill talking about a patent about Future PageRank

BTW, internal PageRank is likely a float between 0 and 1. So people who take a linking page's TBPR and divide it by the number of links on the page to figure out how much PageRank a link might pass is really barking up the wrong tree.
