Google is updating the Pagerank and backlink values.
For anyone who doesn’t know what this means, check out the simple explanation here. If you Pagerank value has changed (you can check Pagerank on multiple datacenters), take note, because it’s the closest to the actual Pagerank value that you will see for the next 3 to 4 months. That’s right, Google only updates it’s public Pagerank values 3 or 4 times per year ( See the Google Pagerank Update Calendar to see a complete history of all the Google Pagerank updates since January 2005), and who knows, the new values may actually be from last month, but at any rate, it’s as current a value as you will see.
So if you are wondering exactly what pagerank is good for, well, not much by itself. Pagerank is one of over 100 factors that Google uses to rank sites in the Google Search results. A pagerank 6 doesn’t guarantee you a #1 position for the keyword of your choice. (sorry :() It is simply a value, calculated by Google, based on the link structure of your site. That means links from other sites to your site (external links) and links from within your site (internal links).
