I am wondering if anyone could clear up some questions I have regarding international SEO and how to treat the content placed on there.
I have recently launched several websites for a product internationally, each with the correct country domain name etc and I have also followed the guidelines provided by webmaster tools on internationalisation.
All the websites are targeted towards English speaking countries and I have rewritten most of the of the content on there to suite the English style of the targeted country. This is being said however I am finding mixed bags of information on what to do in treating large chunks of potential duplicate content. For example my main .com website which has been running several years (and is targeted to the UK) has a lot of well written articles on there which are popular with the visitors. I am needing to find out if duplicating these articles onto the international versions of the websites, without rewriting them, would have a detrimental effect on SEO between all the sites.
I have done a site search for each domain name to see if they are cropping up in other local Google versions (e.g .ca site in Google.com.au etc) and they are not. Does this mean Google is localised to its results regarding duplicate content or is it treated at the root level?
Any information to point me in the right direction would be a big help.
