2 versions of the same site in different countries, how to avoid content duplication?
Hi there,

I have two versions of the same site, one is for the US market and is in American English, hosted in America. The other one will be in British English, hosted in Britain.

Is there a way I can link them, or make it obvious to google they are from the same company, so that only the relevant ones appear in their own countries serps?

Thanks for your help,

You shouldn't use one content for both site,although you have two sites with different language but google algo count as duplicate content so avoid it.
