I've noticed a couple of my sites have went from PR0 to PR1 just overnight from when i've added content. No google update since a week or two back. Is this normal or is somthing wrong here?
I think Google no more updates pagerank at a fixed frequency. Due to overwhelming number of websites, it has to dynamically change indexes and page rank too.
A while back I noticed that one of my websites went from a pr1 to a pr3 then back to a pr1 so I no longer depend on Google page rank! As long as your website has good listings in the search results & plenty of traffic I wouldn't worry about anything else.
One of my sites went from PR0 to PR2 just a couple of days ago too. I did add a couple of new articles prior to the rank going up.
Same thing I faced...I created totally copied content site before a month ago and NOW It has PR2..I amazed to see PR..BUt I don't think this PR will stable for long term...what you think friends?
since last one month i have observe that Google is updating page rank in short period of time which was around 3 months before.. now they are updating frequently, so this is normal things now..
