Canonicalisation

[Dan-Lawrence]

Hi

Im looking at a clients site canonicalisation usage and in regard to some comments the tags referential value is a node (not the same as the actual page url) does this make sense or sounds like incorrect usage ?

For example:

URL  **                                                     ** Canonical Tag

domain.com/comment/6                          domain.com/node/21

Cheers

Just to clarify.  You have a main page or node page, and off of that node page you have various comment pages that are commenting on the node page.   The comment pages are canonical linking to the main page.

I would say this does not make sense.  You would want the comment pages to rank potentially or at least add more to the main page.   I would consider making the comments on the same page as the node page - much like they do on Moz.  Or if you had to break them out, I would make them paginated pages off the main page and then use rel next prev to show the relation to the main page.

Google treats the canonical like a 301 and it usually means that something is a copy of the original.  As new comments are not copies of the original and actually may add to the main page, using the canonical does not make sense.

Different example, I use canonicals for the printer friendly version of a page. It is a duplicate and I want to make it clear why and which one is more important for ranking.
