Double content can only happen by some additional modules or functions. Examples are new products or featured products. If there is a new product on the home page, it is at the same time in its category listed as a product. And if it is also declared as featured, there are 3 links to the same product. Is that, what you mean with duplicated content?
I think it is very difficult to exclude that.

Franz,
I managed to avoid (or reduce) duplicated contents in OpenCart here:

http://forum.opencart.com/viewtopic.php?f=10&t=6677

In my solution, I have to choose that product link is not prefixed by any attributes (category, manufacturer), and suffixes (for example in the search result; I don't get the point why the resulting links are added by search parameters).

So, if originally the content are duplicated across several links, for example:
  • /ipod-nano
  • /mp3-players/ipod-nano
  • /apple/ipod-nano
in my solution, all links are consolidated into:
  • /ipod-nano
wherever it is accessed. This is possible, since rewrite module in OC is done inside PHP scripts, so it is easy to change.

Nice solution.

Has anyone written a decent:

1. robots.txt file to handle duplicate content,

2. 301 redirect in the HTACCESS file to handle all the possible Canconical URLs (more multiples of duplicate content), by redirecting everything to http://www.site.com/ or whatever your url choice is,

http://www.mattcutts.com/blog/seo-advic ... alization/

...and willing to share? It's been fixed for Magento in their forum with these 2 fixes, so I guess its been done for Opencart by someone.

Cheers

robots.txt
solves dup. content if you can match it to a pattern, but doesn't help with link equity going to waste (doesn't stop the CMS creating alternative URLs, and therefore doesn't take preventative measures against other websites linking to you with alternative URLs)

301 redirect
ok solution, but preferable to stop the duplication before documents are parsed.

That's one side of the problem -although I don't understand parsing as I'm a hack :)

The other side is people typing or linking irrelevant urls like:

http://mysite.com
http://mysite.com/
http://www.mysite.com

instead of http://www.mysite.com/

Would the top of the .HTACCESS file look like this?

Code: Select all

RewriteEngine on
RewriteBase / 
RewriteCond %{HTTP_HOST} ^mysite\.com$ [NC]
RewriteCond %{HTTP_HOST} ^mysite\.com/$ [NC]
RewriteCond %{HTTP_HOST} ^www.mysite\.com$ [NC]
RewriteCond %{HTTP_HOST} ^www.mysite\.com/index.php?route=common/home$ [NC]
RewriteRule ^(.*)$ http://www.mysite\.com/$1 [R=301,L]
At the Apache.org website they mention something different which I don't understand, but that's ok.

This issue has nothing to do with opencart specifically, as you are talking about the canonical domain root- and yes, it is a totally great thing to do, even though in the last year google deals with it really well - bing doesnt though.

I don't understand. If your SEO is so great, then why do you need to spam forums to get clients.

The rel="nofollow" is an attribute you can set on an HTML <a> link tag, invented by Google, and adopted by others. Those links won't get any credit when Google ranks websites in the search results, but wont avoid indexing.

Duplicate Content Tool can also be useful to check if your resellers, partners or competitors are grabbing or reusing your original content.
