PR is not so important anymore, after the panda effect has taken place, as many of us have lost money and time in maintaining the sites. BTW the next PR update is gonna be in the next month, enjoy
I'm seeing big drops in PR on domains I've purchased in the last few weeks. Getting hit HARD! Page rank 5 site with PR9. PR7 and multiple PR 5 & 6 links dropped to ZERO! Another PR5 site with strong links dropped to PR1This really sucks big time.
Google keep on changing their algorithem until they don't even know what they are doing. So for those who are in SEO, will have to keep themselves updated regularly. Sometime we just have to be a little bit patient.
It seems like there is a lot of "Bounce" going on. One of my PR 5 sites that went to 0 came back up to 5, and a PR4 site also came back up. . But I still have one PR5 that dropped to PR1 and it's still stuck on PR1 ;( If you have a site that drops but still has strong back links, there is a good chance that it will come back to it's original rank after a few days. The same thing happened to me during the last big PR reset.
