The live page rank, future page rank (RK) or whatever you want to call it speculation over the last couple of days just got some light shed on the subject-sort of.....let me explain: Matt Cutts answered in his Q&A over the last couple of days that the RK Parameter will no longer be showing any other number then 0. This tells you that in fact the live pr tools have been shut off. No one answered why? This is where the sort of comes in. Also the speculation remains as to what exactly the live pr was. Was it the future pr of your site after big daddy? Matt does not go into much detail with this either, other then offering this:
Q: What's an RK parameter?
A: It's a parameter that you could see in a Google toolbar query. Some people outside of Google had speculated that it was live PageRank, that PageRank differed between Bigdaddy and the older infrastructure, etc.
So I guess we did learn two things:
- We know that live-pr will not be showing any other numbers besides 0.
- We know that we still don't fully understand what the tool really was measuring (although we have a good idea now).
It will be interesting to see what new tools will be developed or if this is something Google will keep shut from now on.
