The last huge page rank update was carried out in April 2010, after that we witnessed minor updates here and there for a handful of website but that was pretty much it for 2010. Normally, Google updates PageRank every year in April ever since 2004. This year Google updated its PageRank in January (over the weekend). PageRank is not going to change anything about your website significantly nor is it a sign of a good performing website. Some of you might notice a PR change and others won’t.
