Duplicate content errors

[toejklemme]

I have multiple duplicate content errors in my crawl diagnostics. The problem is though that i already took care of these problems with the canonical tag but MOZ keeps saying there is a problem. For example this page http://www.letspump.dk/produkter/56-aminosyre/ has a canonical tag, but moz still says it has an error. Why is that?

So now i have changed the way the URL works, and today Moz crawled my site once again, but im still getting errors on pages that have a canonical example: http://www.letspump.dk/produkter/61-aminosyre/ which has a canonical that says: rel="canonical" href="http://www.letspump.dk/produkter/5-aminosyre/" > So why i  am still getting Duplicate Content errors??

Might want to double check  -

"Avoid errors: use absolute paths rather than relative paths with the rel="canonical" link element.

Use this structure:  http://www.example.com/dresses/green/greendresss.html
Not this structure: /dresses/green/greendress.html)."

Also have you given enough time for Moz to recrawl your site and pick up the changes?

I´ve just checked this with Google employee, and we are using absolute links which are working just as well, so there should be not any errors.

You need the full url so the tag should look like-

<link rel="<a class="attribute-value">canonical</a>" href="http://www.letspump.dk/produkter/5-aminosyre/" >
