Google updated their Tool Bar PageRank (TBPR) last night, October 29, 2009. I noticed the change around 9 p.m. last night, when I visited CNN.com and saw an all-green PR 10 tool bar, which caught my attention immediately. Previously, I believe they were PR 8.
With the lastest update, the WordStream home page (now PR 5) and many of our top level pages have risen in rank. So too have our blog posts, with many previous unresolved pages resolving and now achieving TBPR.
