Google Pagerank Update

Google is in the midst up updating pageranks across their datacenters. Yes Google pagerank is not the holy grail some used to see it as still it is a very easy shorthand to get some idea of how much significance a page has. In concept it

You can track the progress using SEO Chat's tool. We moved our management blog from blogger (where this is hosted) to a wordpress blog a few months ago. It is nice to see that the new pagerank for our management blog is 5. We seem to have no trouble getting pages with pagerank of 5 but getting to 6 is rare. The lowest 5 site would also be nearly 10 times less than the highest 5 site (so the single pagerank number is a very rough guide indeed).

Pagerank is a logrithmic scale (so a pagerank of 6 is 10 times a 5 and 100 times a 4). Still it is surprising how easy it is to get to 5 and how difficult it is to get to 6.
