I been using this tool and when check for duplicate content, the following is listed:
WWW/NonWWW Header Check: FAILED
Your site is not returning a 301 redirect from www to non-www or vice versa. This means that Google may cache both versions of your site, causing sitewide duplicate content penalties [SHOW ¦ HIDE].
Headers for http://www.example.com: HTTP/1.1 200 OK Date: Wed, 08 Jul 2009 01:51:08 GMT Server: Apache X-Powered-By: PHP/4.4.9 Connection: close Content-Type: text/html ===== Headers for http://example.com: HTTP/1.1 200 OK Date: Wed, 08 Jul 2009 01:51:08 GMT Server: Apache X-Powered-By: PHP/4.4.9 Connection: close Content-Type: text/html
Google Cache Check: FAILED
Google may have duplicate copies of pages on your site due to indexing both the www and non-www version of your site shows 21 pages cached, while the www version shows only 15 cached. Unless your site has subdomains, this often means that some duplicate content penalty may exist.
Similarity Check: FAILED
Google indicates that it has "omitted some entries very similar" to the top 1000 pages on your site. This similarity is a duplicate content penalty preventing these pages from being considered uniquely valuable in Google's index.
Default Page Check: FAILED
You have not standardized your default pages meaning the following versions of your url return a 200/OK Header, which may cause duplicate content issues.
However, I used the server header check from here [webmasterworld.com...] and it looks like its ok.
HTTP/1.1 200 OK
Date: Wed, 08 Jul 2009 02:04:43 GMT
Server: Apache
X-Powered-By: PHP/4.4.9
Connection: close
Content-Type: text/html
Server response time:less than 1 second
So what seems to be the problem and why is my site list as a duplicate content?
many thanks in advance
CHEERS :)

Here's a previous thread that goes into detail about this kind of canonical problem: [webmasterworld.com...]
