Ok, there have been a ton of talk on Google Rollback due to different PR values which have fallen drastically. I happen to have extremely detailed information on how we can conclude that this is definitely a Google Rollback. However, since I am not part of Google Staff, I can only be 66% sure that this is, in fact, a simple rollback.

Please note that I use SEOChat’s Future PageRank Checker - which basically checks multiple Google Datacenter for the Pagerank of a given website.

Sixty6 Arcade is one of my personal arcades that I have been running and promoting for a couple of months. If you notice, I linked to the non-www version. This is because the script experienced some problems with the non-www version, so I did a 301 .htaccess redirect.

I had a PageRank of 4 for the www version of my domain name. However, after I did the 301 redirect, Google decided to do a PageRank update at the moment, and since barely any of the new redirected pages have been indexed, they assigned me a PageRank 3.

Now take a look at the results for www.sixty6arcade.com and you will notice that it has a PR4 on one or two Google Datacenters:

Now take a look at the results for sixty6arcade.com and you will notice that it is all completely PR3.

This means that Google is assigning different pageranks for the two different types of domain names. But since I’m doing a 301 .htaccess redirect from the www-version to the non-www version, would it not be the same PageRank?

This is my speculation, and I make no guarantees, just a well-supported argument!
