I've got a page which displays search results and I've added rel=prev and rel=next meta tags to the page to cover the paging. However, someone is saying I should also add a rel=canonical tag to the page that points to the start page of the search results. So for example, say we're on mysite.com/search/xyz/page5 the canonical tag would point to mysite.com/search/xyz/
Is this wise? isn't the purpose of the prev and next tags to tell the SE that all these pages are of a set? But then putting the canonical tag in there is sort of telling the SE that the first page is unique and not part of this set?
According to that video from google, it sounds like we should not use the canonical link. But i just looked at ebay and they are using the canonical link instead of prev and next. Then again maybe they are showing a different page if you are bot instead of a user.
The problem we are having is that if we go into google webmaster tools it's showing all the paged results on our site as having duplicate content (duplicate title and description). Is that really a problem? Do i need to do something kind of stupid and just put the page # in each title and description?
