PR Dropping & 0 now :(

Hi..
I have a site,where I always keep on writing articles . And get a lot of SEARCH Engine traffic as well for all of my keywords..

I lauched this site on July 2008.
On september 2008, I got a PR3.

Then on March or April 2009, it dropped to PR2.

And today when I see, its PR0.

What can be the reason ?

I have all my hand written articles and all are tutorials. So, no question of duplicate contents or whatsover.

I need to know,so that I can work on those areas.
Thanks.

 

are you sure the site has no any duplicate content?
do you use any trick to link your site from anywhere?

 

NO! Not at all.
And No Duplicate Contents also, but topic can be similar like,
"HOW TO FIX THE FATAL ERROR IN WORDPRESS"

Like this..

 

What have you been doing for SEO in the last year?

 

my blog dropped from 2 to 1 but i think it is normal.
about urs i think you should keep updating your website and keep your SEO plans

 

this is normal my pr3 website is pr1 now .

 

Yes this is pretty general, you should wait until next update I'm sure the Pagerank will get back.
