Over the weekend, I have seen tons and tons of threads in several forums with webmasters and SEOs complaining that their PageRank score in the Google Toolbar took a dive.
I will just list two threads, because I cannot list all of them. There is a thread at DigitalPoint Forums and Google Webmaster Help.
The thing is, I didn’t see anyone happy with the new PageRank score they received. If you look closely at the Google Webmaster Help you will see, Googler, JohnMu say:
So, with this guys particular site, there was an issue exporting his site’s PageRank to the Toolbar, during Google’s quarterly export. There may have been other issues with other pages impacted by this export.
I don’t know for sure, but what I do know is that we should not worry about Toolbar PageRank.
