how i can use one website with different domain name ?

Today some one ask me, that he can use his website .com use in multiple countries with multiple domain like .co.uk, .in and other . after this , Is it create duplicate content issue or not

 

its not clear. what exactly do you need?

 

both sites remain live and have the same content or you only want to stay with the .com.

 

NO you can't ! unless you buy the specific domain like .fr .de or whatever and name it like your then copy your site to it or just make a redirection to your initial website

 

The only safe way to promote multiple domain names pointing to one Web site is to 301-redirect all the secondary domains to the primary domain. Search engines recognize the 301 redirect as a valid method of permanently rerouting traffic from one domain name to another. This will Not have any Duplicate Content Issues.

 

Do you mean with only one .com domain you can geo target different countries? If so, you can have for instance domain.com/en, domain.com/es etc, and setup hreflang properly. Follow this instructions: https://support.google.com/webmasters/answer/189077?hl=en

 

Just use your own domain and create different folders for every page:

Like:
yourdomain.com/de, yourdomain.com/en, yourdomain.com/ru, etc.
