Sorry if this isn't the right forum to post this thread in, as I'm new here, but after a bit of looking around this looks like the place. I heard (I don't remember where) that when one site links to another, the amount of pagerank given is equal to that site's pagerank divided by the number of links on that page. So, if site X has a pagerank of 4 with four links on a page, and site Y has a pagerank of 0, and site X links to site Y, site Y gets a pagerank of 1? Can anybody confirm this?
You could have a look at a page compar did, it has a chart etc http://www.compar.com/infopool/articles/PR-calculation.html apart from google no one knows for sure how it all works numbers wise.
One amendment to that article - the PR passed very probably now depends also on the relevance of the page passing the PR. There is almost certainly less PR passed from a site on an unrelated topic than one that is closely related. Ironic, because at the bottom of that same article are links to poker, drug stores etc
I do not think that is the case. TSPR (Topic Specific Page Rank) would be a great contept, but I do nt think that it has been implemented. Note, there might be greater link value if the topic of the linking site is related. I am not disputing that. I just think that the PageRank is not altered by the topic of the linking page.
Ajeet is correct: PageRank is still PageRank and still determined by number and quality (PR) of incoming links to the page. Ranking of a page is a different matter of course. Other factors like link relevance are probably (I would say almost certainly) applied along with PR and numerous other factors to determine how the page ranks in Google's search results.
Well, my results show that one PR4 can supply like 10 pages with PR3 because it is like PR5 is like 10x PR4, and PR4 is like 10xPR3 ... however the correct number is secret; Anyway, in theory it is like if you have ROUND PR4 then it will be caculated like this: Pr4 * .85 / 4 = 0.85 but as the assumtion we have like PR 0.15 by default, it will eqaul a PR1 to your page by theory; but again, PR is not absolute values it is like points; and say having PR4 could be from 40000 to 44444 and you will see PR4 or 48888 will show PR5
