I've noticed that my toolbar is acting strange. Just noticed one of my sites that is brand new, is listed as a PR8. It will fluctuate between PR4-PR8. Anyone else seeing this? Also says my site is listed under
It's fairly common to get some PR flux right before an update. Most people don't see it as their PR doesn't change every update, but those who do see it are the ones who tend to be about to move up or down. (Note, don't fear if you're moving down, I've found that moving up or down one has little effect on your overall traffic - you're right on the brink anyway. The bar works with whole numbers, but in reality, PR doesn't work that way).
It makes sense - PR MUST be calculated before they update because it does affect ranking in some way. It's just a sign that we're due for an update - which most of us already know.
I noticed that the PR is carried forward from the previous web site visited. I think it's a bug in the toolbar. Notified google, but they said it was something on my system. I doubt it. It just started yesterday.
I did like it when I went from the google home page to my websites home page. PR10 carried forward to my unindexed home page. Had to take a screen shot of it. Doubt I'll see it again. ;)
