Many of my internal pages had changed PR 0 to 1, and 1 to 0. Some of the site I have backlinks changed their pageranks as well.
PR is not as important as everything believes it is. Your PR can drop to 0 but you still show up same in SERP. So really whats the point of PR?
I have noticed the same thing I have several client sites that where at 1 or 2 and are now at 0. All of the sites that I have are down to 0. There has certainly been a change in how page rank is calculated. While many say page rank is not important I have also noticed a drop in search results. I suspect their has been a change in the search algorithm as well.
I'm seeing no signs. Are you sure you didn't miss something from the minor PR update a bit over a week ago?
I noticed the drop in search rank last week. I noticed the drop in search rank before I noticed the drop in PR. I don't make a habit of checking PR. I don't particularly care about it. As long as I am ranking. I had 2 sites page 1 generally 1-3 position. They both dropped to nowhere. Gone. It was a pretty crazy day to say the least. Trying to find out where my site went.
I noticed a huge drop in my rankings today. I was have an exact match .com domain for a keyword that only gets searched for around 30 times per day and have been in the top 3 since I launched the site last month. All of a sudden today I have fallen out of the top 200. My site is still being indexed though. I'm thinking either they changed something or I've been sandboxed.
Some days before it was minor update but i dont know when is the next update! I think it should be in July!
The point of PR is being at the top of the serp or "just showing up" somewhere on page 2+. Higher the PR, the more likely you will be at the top of serps. Google clearly has stated this.
