What is a canonical tag?

The canonical link tag tells search engines which URL is the preferred version when duplicate content exists.

Where does the canonical tag go?

In the section of the page, one canonical per page pointing to the preferred URL. It can point to a different URL than the one a visitor is currently on — that is the point of the tag.

Can canonical tags point across domains?

Yes. Cross-domain canonicals are valid and are the right way to handle syndicated content that should credit the original source URL instead of the republished copy.
