Hi there - is there a canonicalization method that is better than others?

Our developers have used the

I always try to use the rel=canonical tag wherever possible - however, it is only a suggestion to the search engines. They can decide not to use your suggestion.

301 redirects should really only be used when the page has permanently moved or dramatically changed (by this I mean the layout, design etc.) - domainA.com/content to domainB.org/content. By using a 301 redirect you will lose 5 to 10% of link juice and you will also lose any social shares received.

Also worth remembering that if your content eventually changes on the new page, the old canonicalization tag will no longer apply as it will now be pointing to different content.
