Matt Cutts: Duplicate Content
link rel=
”canonical” value =
”https://www.example.com/page.html”/>
This is a hint not a directive/mandate/requirement. Search engines choose when to use the suggestion.
This doesn’t work across domains…only the same domain but it does work across the same domain / hosts. Similar to a 301/perm redirect. Pages don’t have to be bit-for-bit identical, but they should be similar. Can use relative or absolute url’s, but absolute url’s are recommended. Can possibly follow a chain of canonicals but don’t count on it.
Matt: High page rank means Google will more likely crawl you deeply.
Matt: Can’t 301 a penalty to a site that’s not yours.
Matt: Google Japan needs to held to the same standard as anyone else…Matt manually lowered the Page Rank of Google.co.jp from 9 to 5.
Matt: Much more harsh with link sellers as opposed to link buyers.

The announcement of the canonical tag is pretty big. Could be a great tool in combating problems with large CMS sites ..
