MY PR 4 to 0 in this month :(

hi friends

i got an problem with my indexing of google

kindly check this site:www.smashinghub.com to search in google, it is not indexing with www.smashinghub.com

but it is working like this smashinghub.com

any one reason
thanks

Is your content original?
I got a quick look and saw a lot of either duplication or syndication. Good google be getting confused about your content?

yeah content is original, this is not problem,

why it is not indexing with www at google

Ah, you can take care of this in google webmaster tools. You have to claim both with and without the www. Then you can assign the primary site.

i tried with both, but problem is , my sitemap generted an error with www.smashinghub.com/sitemap.xml

than i redirect to edit on .httaccess page

but it is fine with smashinghub.com/sitemap.xml

if u can search smashinghub.com at google, it shows only “Smashinghub” it is not showing the full title “Graphic Design inspiration of digital photography and photoshop tutorials”

now i added my site along with www.smashinghub.com and smashinghub.com , separetly…
is that okey?

another reason

"Error loading stylesheet: An unknown error has occurred (805303f4) "

its shown me this error while www.smashinghub.com/sitemap.xml

this time , i removed my .httaccess file (redirect code) kindly check what type of error
thanks

Now in Google Webmaster Tools go to
Site Configuration > Settings > Preferred Domain

hi sir

check this setting, i am giving u screenshot


and also i redirect in .httaccess this code

RewriteEngine On
RewriteCond %{HTTP_HOST} ^www.smashinghub.com [NC]
RewriteRule ^(.*)$ http://smashinghub.com/$1 [L,R=301]

Please check your is penalized or not. I faced same problem when my site was penalized.

Hi!
You can check your cpanel or if you don’t have cpanel then you can use Google analyzer to search targeted traffic resources.

Well it is really strange and like shocking for me to hear that a site goes from PR 4 To PR 0.
What i believe the reason behind such drastic change is penalization.
What is the way to check whether a site is penalized or not.?

Me too thinking the same, you have 2 make them original and quality,

hello you are update your site that html code

<link ref="“canonical” href=“site url”/>

that html code are benefit for your site, using html code and do not open without www.
