  1. Duplicate content is an old tactic and thanks for google updates. I beleive they are not using it anymore. But canonical tag is good for the websites who are publishing same content under different listing pages.

  2. Ive created a automated canonical rel, when everything is fine i want to display a messege, Automated canonical by such and such, dus resulting in 404, does this affect the indexing and ranking?…Does anybody know?

  3. GREEEEAT video, Matt!

    But I've got a question: you mention (around min 4:30) that on webmaster tools we can choose between 3w or non-3w versions. I've been looking into it for around 10 minutes now and can't seem to locate where I can actually set that up. Can you help me on this one? o.Ô

    Thanks!
