Google see 2 versions of my site: www.mysite.com and mysite.com

[Kangol]

My site was recently penalized by Google. I guess that it’s the duplicate content penalty. It is an affiliate site and some pages had content from the affiliate firm I promote. When I do a search my keywords with the &filter=0 my site ranks as it used to do for my keywords.
Now I noticed that Google had indexed 2 versions of my site: www.mysite.com and mysite.com.

mysite.com is cached on Jan 2
www.mysite.com is cached on Jan 9

So Google is treating them as 2 different sites. I’ve started to rewrite the content of my duplicate pages and I hope that I will get rid of the dup penalty but what should I do with the www.mysite.com and mysite.com versions? Did any one got rid of the duplicate content filter by rewriteing the site content?
Thank you.

Hello Kangol,

I have a very similar problem. My entire website was crawled without the www. but my homepage shows as "www.site.com"

It appears google treats them as different sites. The index page with "www" ranks even better than content pages without.

I have tried to merge the site listing for a year now with no success.

I tried 301 redirect but it didnt work for me. Google asumed there were duplicates of pages. I will stay away from 301 redirects from now on.

I have absolute linking in all the site but even so, google does not get it.

I do not know what else to do

Sorry this is not really an answer, instead I join your question.

I had this happen to two sites a few months ago. I added a 301 redirect to my .htaccess file and it worked great for me. It took about six weeks for Google to merge the two urls and transfer the page rank. Then the sites went back to ranking where they were. I chose to use the version of the urls without the www. because most of my incoming links didn't include it. I put this in my .htaccess file.

RewriteEngine on
RewriteCond %{HTTP_HOST} !^sitename\.com
RewriteRule ^.*$ [sitename.com%{REQUEST_URI}...] [R=301,L]

If you want to use the url with the www. you need to add it.

RewriteEngine on
RewriteCond %{HTTP_HOST} !^www.\sitename\.com
RewriteRule ^.*$ [sitename.com%{REQUEST_URI}...] [R=301,L]

I was having the same problem - a bunch of my pages were showing up under mysite.com and www.mysite.com

Think it was do to me giving 302 redirects from
mysite.com/page.html -> www.mysite.com/page.html

I now do a 301 from mysite.com/anypage.html to www.mysite.com (root of site)

They aren't all gone yet - but some are gone - so it seems to be in the process of working.

One way or another they were showing up as "supplemental results" - so I don't think it was having a major impact.
