Questions about rel=canonical
I’m already getting questions about the new rel=canonical standard. And I have several of my own. I’m going to put them into a post here. If you have your own, leave ‘em in the comment thread and I’ll move them into the post:
- Shouldn’t we just add link rel=canonical to every single page on our sites? Wikia, which Google cites in their example, appears to have done that.
- How much link authority will the canonical tag pass? 100%? 90%? Less?
- How will each search engine support the new standard? What differences will there be?
- What if rel=canonical conflicts with the canonicalization settings in Google Webmaster Tools?
I will post answers as I get them.
