Pagerank Question
Just simple question about PR. If side A (PR4) has 1 outbound link, and that link is to site B, and side B has no returning link to side A, and side B has (pr1), than side B with time should get PR5.
Is that right?Last edited by moospot; Jun 30, 2005 at 12:23. Reason: self promotion

No, the page rank algorithm used in the original Google paper is not defined like that. The algorithm used then was: PR(A) = (1-d) + d (PR(T1)/C(T1) + ... + PR(Tn)/C(Tn)) and I would assume there are some other changes that have been made.

NoIs that right?
It'd be too easy to obtain PR10 in such case

Keep in mind that PR and rankings is on a per-page basis, not a per-site basis. That said, no, your logic is slightly flawed. If page A links to page B, and page B has a PR1, and page A has a PR4 with just the single outbound link, then page A will give 85% of the PR4 to the other page. This would probably end up with another PR4 page, since a PR1 is worth next to nothing. Also keep in mind that PR is not linear -- (PR2 - PR1) < (PR3 - PR2) Originally Posted by jackar000

you could test this with the PageRank Decoder at Search-This.com
the answer is, if everything is as you say, page B would have a PR value of 3.55.WordPress Plugins: Comment Info Tip

That looked good until I put two PR4 links into a page - apparently the receiving page would be PR6.85! I dont think so! Originally Posted by Golgotha

Then I added a PR10 link, and it came out as PR15 lol

that's because you set a pages PR artificially - it wasn't calculated to a 4 - then ran the calculation. Google doesn't do that, all pages start with a 0 or 0.15 PR then start calculations.
So it's accurate if you start all pages at 0 then create the link structure and go from there.
I talk about this in the FAQ.WordPress Plugins: Comment Info Tip
