Did you notice a change in the PageRank of your website? We definitely did, our PageRank increased, and we are gleeful about it. This happened because Google has updated its Toolbar PageRank, the first update for 2013. Many website owners have confirmed a change in the PageRank of their webpages oin forum discussion on DigitalPoint.
Google usually updates its Toolbar PageRank every 3 months. Even though the importance of Google PageRank has declined in the past years, but it is still a part of the algorithm.
The previous Google PageRank update happened in November 2012.
