ive just used http://www.futurepagerank.net and it says some of the datacentres give me site 1 PR and the rest give it another, why is that? the otherday they all gave the same now some of them have dropped
It's make no sense, I advice You don't use that tools. However, if You like it - try http://rankit.free.fr/ It's the best 'magic sphere' on the web I guess.
All future PR tools have been telling me that my site is going from a PR3 to PR4, but after every toolbar update I still stay at 3. The tools are for entertainment purposes only.
I haven't found any reliable way to predict what the next PR will be for a site. Frankly I think it's a waste of time. You should be creating content or getting backlinks instead of chasing PR.
i think it's crap or hope it is, shows me going from a 4 to a 3 or 1 depending on center.. and i'm far better backlinked etc now then i was at last update
