I am a bit disappoint with Google Pagerank Update for February 2012 when there is no updates yet for Cariblogger.com to rise from PR5 to PR6. Cariblogger was previously ranked as PR6 in 2009 but dropped to PR5 at the end of 2010. Moreover, some keywords that have been in the Google SERP first page for more than one year has fallen to second page, which I believe due to some updates from Google search quality improvement to reduce the site that contain too many ads above the fold.
However, there are 2 of my site that show a little bit of improvement in this first Google Pagerank Update in 2012. I hope that we will learn from past mistakes and improve more in the future.
