Rel alternate use for multi regional website with english language and same content

[HiteshBharucha]

I have a website targeting multi language and multi regional users.

For example, my main site is www.abcd.com which is in English and targeting US. I have the same content in English which is targeting UK and India with www.uk.abcd.com and www.india.abcd.com.

I want to avoid content duplication and help search engines to show the right pages on the country level searches. I have researched a bit and have come to conclusion of using re alternate tag. Can someone help me with how to place the codes for the same.

Many thanks Mozers!

Add this to header of each site. The following code is for the homepage:

Hi Oleg,

Thank you very much for the response.

One more thing, do i have to put this code on each and every page which has been replicated or just on the homepage?
