Have we beaten the Google Toolbar PageRank value dead yet? If not, here is yet another reason not to take too much insight to the value displayed in the Google Toolbar.
The other thing is that the PageRank shown in the Google Toolbar is only updated periodically, usually every few months, and is only an abstraction from the constantly updated number our algorithms use. In the time between updates, any number of things can happen to the other sites that link to you, and the sites that link to them (and so on) so it can be hard to predict how the little green bar is going to move.
So instead of all the craze PageRank update threads which we actively promote here because they are discussed more than any other topic in the forums, we should probably focus on other things? Why? Let me pull out points from Berghausen post, which I quoted above:
- Toolbar PageRank is only updated periodically
- Toolbar PageRank is only updated every few months
- Toolbar PageRank is only only an abstraction from the true PageRank score
