I don't know specifically why any one site would go to PR0, but one thing I have seen alot of lately is configuration errors on your own site. It seems more important now for Google than ever. One common mistake is in configuring your .htaccess with an error page for a php site - see this post: http://forums.digitalpoint.com/showpost.php?p=982890 Check your server headers. Google has been playing with redirects, I would avoid any 301, 302 or meta-refreshes unless absolutely necessary for awhile. Seems that they are actually trying to fix the 302 hijack exploit finally. (See the Bug Track section.) If caught in one, it can PR0 your site and tank your rankings. There are good suggestions there for avoiding/fixing one. Anybody: feel free to PM a url if you suspect this problem, I am looking to see if it really is fixed. I have not seen one in awhile...
Congrats! I think you deserved that. It seems that lots of people got PR5 or above in the latest update.Except me
My main site is a PR6 which is nice, however on of my sites that I'm trying to build has dropped from a PR4 to 1 PR1 - Lucky me! If anyone wants to have a look and see what the hell might have happened, the site is www.leasingandcontracthire.com Damn you Google.. I'm at your mercy once more Martin
Don't the pr updates happen at different times depending on what region you are located in? I'm pretty sure some of my sites should have gone up in PR but it hasn't happend yet. But maybe Google hates me PageRank is a patented method to assign a numerical weighting to each element of a hyperlinked set of documents, such as the World Wide Web, with the purpose of "measuring" its relative importance within the set. The algorithm may be applied to any collection of entities with reciprocal quotations and references. The numerical weight that it assigns to any given element E is also called the PageRank of E and denoted by PR(E). -wikipedia
I think updates are still ongoing. Try checking with different PR tools and you get different results. One says PR3, another one says PR5. You can confirm this if you check multiple Google servers.
Try again next update. Mine is still solid PR5. Congratulations to all who get what they want. And try again next time for those who didn't make it.
PR is definitely very important but it does not tell the whole story. We have clients with PR4 sites ouranking PR5 and PR6 sites all targeting the same main keywords. PR is not the only factor. Keyword density and frequency, domain age, content, code etc are all part of the equation. For example, I have a friend who has had a domain and site up since the mid 90s. He has a PR6 and practically no incoming links. His site does not even rank in the top 100 for the keywords he is going after. The site is fairly clean and the PR is due to the site just being up for so long.
