Duplicate Products in Multi Country

[victortan429]

My store is in multi country example , Singapore , Australia, New Zealand. For my store default is based Singapore, and in different country have different pricing too. At this moment I am using Mlveda for bulk edit multi country pricing. 

So my question here is : do I need to duplicates the products and rename it as [product name] + [country] ? 
as my purpose is to reach the best SEO result. so for example in New Zealand store , it will show [product name] New Zealand.

Any ideas ?
