PR doesn't work like it used to, and so I am confused as to what is going on (nothing new).
I have a site which was linked to by a PR5 and a PR4 and I expected to get a PR4 or PR3 from this.
It only made PR2, which I thought was lower than the old days.... but hey!
So I decided that because the target keyword was too hard to manage with a PR2, I would not bother to waste a link from the PR5 on it and wind the site down, as the idea for the site was not too profitable anyway.
So I pull the PR5 link and then about 2 months later, the site still has PR2, but has managed to get into the top 20 for the keyword I wanted, and has one PR4 backward link.
