Google has just begun rolling out the PageRank updates for January 2011. Many websites are seeing increase in their PageRank while some are seeing decreases.
Google usually rolls out toolbar PageRank updates every quarter, however, there weren’t much of these updates in 2010. You can check the PageRank of your website by using our PageRank checking tool.
Google’s PageRank signifies the rank of a website on their toolbar, however, the PageRank does not suggest that your site will show up higher in the SERP. So take it with a grain of salt. There have already been several discussions about what a PageRank is so you might want to read up those to understand how it works.
