Good news for SEO-Tutorial and probably many other webmasters. Finally after 9 months of waiting Google launched another Pagerank Update on January 20th 2011! Changes can be seen on major websites and more will follow!
You can check your website’s pagerank using different Pagerank Tools like PR Checker.
Update: It seems that not all website have been updated. So far only the website created and backlinks before June seem to have had any affect.
