Page_List pagination and Canonical URLs

Permalink 1 user found helpful
In looking at the Google Webmaster informationfor a site running on C5 v5.4.2.2 I am seeing quite a number of references to the child pages that are created as a result of turning pagination on in the page_list block (they all have ?ccm_paging_ in the URLs... and Google Webmaster tools are pointing them out as parametric URLs that might need additional info so Google knows how to index them).

I was thinking that it would be a good thing to add a rel="canonical" tag to the headers of those pages... pointing back to the "parent" or "first" page of the pagination. This should help Google to simplify its index (all the sub-page content would get indexed as being on the "parent" page) and ensure that anyone clicking on search results will get to the main page... not directly to a child/paginated page.

But I'm not sure where to begin looking in order to add something like that to the header of each of the paginated pages. In searching the forums, there is lots of generic talk about paginating... and some more detailed talk about canonical references... but nothing that seems to indicate how to integrate the two.

Thoughts? Anyone ever done this before?

Thanks!
