Google hasn’t updated their pagerank in a long time. But I was looking at my own SEO blog here and noticed all of a sudden the Pagerank go from 0 to 4 here out of the blue. According to the Search Engine Roundtable, the last Pagerank update was in January of this year. So, the official date that supposedly they updated the Pagerank of sites is on June 27th, 2011.
Congratulations to all those who’s rank went up, but for all those who didn’t get it right away, don’t worry about it too much. I had a pagerank of 0 for a little over 7 months, but here it is at 4 in less than 3 quarters.
