Hreflang tag could solve any duplicate content problems on the different versions??

[JordanBrown]

I have run across a couple of articles recently suggesting that using the hreflang tag could solve any SEO problems associated with having duplicate content on the different versions (.co.uk, .com, .ca, etc).

here is an example here: http://www.emarketeers.com/e-insight/how-to-use-hreflang-for-international-seo/

Over to you and your technical colleagues, I think ….

yes. That's pretty much the whole point of the hreflang tag.

It tells crawlers that "this page.co.uk is the same as page.com, but i want you to show the .co.uk version to people in the UK).

Yep - this is the purpose of the tag and by all accounts, it works well. It has been supported since late-2011, I believe, and I've both had no bad experiences with using it, nor have I heard stories of it not working properly.
