Hi
Im working with a site that has ALOT of duplicate content and have recommended developer fix via correct use of Canonicalisation i.e the canonical tag.
However a US version (of this UK site) is about to be developed on a subfolder (domain.com/uk/ & domain.com/US/ etc so also looking into adopting the hreflang attribute on these.
Upon reading up about the hreflang attribute i see that it performs a degree of canonicalisation too.
Does that mean that developing the international versions with hreflang means there's no need to apply canonicalistion tags to deal with the dupe content, since will deal with the original dupe content problems as well as the new country related dupe content, via the hreflang ?
I also understand that hreflang and canonicalisation can conflict/clash on different language versions of international subfolders etc as per: http://www.youtube.com/watch?v=Igbrm1z_7Hk
In this instance we are only looking at US/UK versions but very likely will want to expand into non english countries too in the future like France for example.
So given both the above points if you are using hreflang is it advisable (or even best) to totally avoid the canonical tag ?
I would be surprised if the answers yes, since whilst makes logical sense given the above (if the above statements are correct), that seems strange given how important and standard best practice canonical usage seems to be these days.
What best ? Use the Hreflang alone, or the Canonical tag alone or both ?
What does everyone else do in similar situation ?
All Best
