Just because you havent seen any changes doesn't make it a 'false alarm' People experience changes at different times, their is no doubt in my mind an update IS going on, and it will go on over the next week or two probably.
1. Just because there is no doubt in your mind also does not make it so. 2. Yes people experience changes at different times but it is typically by Continent so all USA based sites would likely see a PR change near the same week. Next would be those near the UK then Mid East and finally Asia. 3. PR is updated daily to Google employees. 4. What you are waiting for is a toobar export which is basically the scoring of websites from 90 days ago...... 5. There has to be more productive things to do than insist there is a useless PR update going on.............basically anything is more productive.... including sleep.......... Sign me Unsubscribed!!!!
I think an update is happening cause last time I created a new page on one of my sites that wasn't even indexed and it was showing a PR4. The last time something like this happened was a PR update.
I am not even saying theres an update - perhaps they just rolled out a new algo' that spots something else and dishes out penalties or similar - perhaps a few of our sites have just been sniped by the goog - doubt its an update - think we just got got!
