Yes, listen to what webcosmo said just above. He's right. I wouldn't worry too much about it even if your PR does go down. For several years one of my sites was PR5. Then, with one PR update, it went down to 3. I was really shocked. We had more links than ever, we had great traffic, SERPS were good...we hadn't changed our site structure, linking strategy, etc. Just couldn't figure it out. While the site was PR3 - for over 3 months - our SERPs didn't decline and neither did the amount of visitors to our site, which actually increased. It was business as usual. The only thing different was that little green bar... And, 3 months later we were back to PR5. I still don't know why it happened. (Now, a year later, the site is PR6, and still going strong.) So being PR3 rather than PR5 was inconsequential (though I admit I just hated seeing that PR3 on my toolbar). So whatever happens don't sweat it ~ concentrate on SERPs, creating content & good solid backlinks instead. best, Denise
I'm sure there are many people that are sweating like you too. Don't worry! Wait till the update is over.
