April 2009 PageRank update
While such an update has little to no impact on your search engine rankings, it’s an interesting indicator as to whether your SEO efforts are having any effect or not. If you include Toolbar PR as ONE of your metrics then you can get a decent overall view of your efforts.
If you want to check your own Toolbar PR then either install the Google Toolbar or use one of the many pagerank checking websites out there. My preference is http://pr.blogflux.com/
