Despite canonical duplicate content in WMT

[Leonie-Kramer]

Hi,

2 weeks ago we've made big changes in title and meta descriptions. To solve the missing title and descriptions. Also set the right canonical. Now i see that in WMT despite the canonical it shows duplicates in meta descriptions and titles.

i've setup the canonical like this:
1. url: www.domainname.com/category/listing-family/productname
2. url: www.domainname.com/category/listing-family/productname-more-info

The canonical on both pages is like this:

I'm aware of creating duplicate titles and descriptions, caused by the cms we use and also caused by wrong structure of category/products (we'll solve that nest year) that's why i wanted the canonical, but now it's not going any better, did i do something wrong with the canonical?

I'd guess that WMT will simply pull duplicate titles from your site and not take rel-canonical tags into consideration.

Is that exactly how you have the URL written? If so, I think your problem is the missing http://

From webmastercentral:

"Specifying (a relative URL since there’s no “http://”) implies that the desired canonical URL is http://example.com/example.com/cupcake.html even though that is almost certainly not what was intended. In these cases, our algorithms may ignore the specified rel=canonical. Ultimately this means that whatever you had hoped to accomplish with this rel=canonical will not come to fruition."

hi, no sorry the url is written  as http://www.domainname.com/category/listing/product-name

it's possible WMT takes the duplicate pagetitles, i have to change that.
