What happened to my site's PR?

My site has been online for about 13 months.
Its PR was 0 before June 27th,2011.
And its PR increased to 3 on June 27th,2011.
However,I checked it on July 18,2011 and found that it decreased to 1.
In the past,there was only one record when I searched "link:mysite.com" on google.
And there are five records when I search "link:mysite.com" on google.
I thought PR should have been increased.
What happened?
Please help me out with it.

it happens i have heard the same from many people on different webmaster forums this is due to google recognition of your page.

Hi Scriptbazaar,
Thanks for your explanation.   
But I heard that Google carried out recognition every three months.
And it is only 21 days from June 27th to July 18th.
I am a little confused.
Does Google carry out recognition regularly or randomly?

I think you know that all algorithms are changing and all what you need is find the way to follow all changes.
Good luck.

Even i've gone through the same stuff!!!
My site's PR was 2 and then changed to 3
and once a sudden it fell to 2!!
Even i am confused!!!!!!

Site PR means assign the value of your site by Google.

Hi Pacifich,
Do you have some suggestions on how to find the way to follow all changes?

 
scriptbazaar  do you have any methods to solved the problem?

Folks, there is nothing you can do to "solve" the PR rollback by Google.  If Google diminishes the inbound links, then your PR drops.  All you can do is keep creating more links to your site.  When Google does another update you may see your PR return back.  Google tries to keep everyone confused.  I wouldn't be concerned about it because there is nothing you can do about.  That is exactly what Google wants you to do is fret over their control of the internet. 

I actually check this out with Google themselves and the PR drop is from the number one reason selling links according to Google.

Different tools show different PRs?
I don't think so.
I have tried mamy different tools.
But all of them show the same PR for my site.

I think you need to improve your forum activity

I think you should generate do follow backlinks. Google is constantly changing website's page rank.

The only internal page I can see with a pagerank is the /canada with a pr4, /hot-water-softener-works with a pr1. The rest are either na or pr0. Did all the other pages go offline for some reason, an adjustment to robots text?

Maybe googlf\e has renewed the Data

Ugg boot styles turned out to be debate for a shoes manner piece, however very good Uggs may not be cheap, so there are tons connected with people today hunting for solutions to obtain low-cost Uggs.

me too, I feel so sad, you know i spend many times on it

My site's PR decreased to 1 again. :(

Don't worry about the pr. Try to get good ranking on the top pages of the search engines. It will help you to get targeted traffic & automatically your website will get a good pr...

what happened with pagerank today, I saw some blog yesterday normally. but ... ...my site PR ..n/a and 0 from PR 3...., 4 site from my all site .
